Taxonomy, distribution, and conservation status of a rare arboreal lizard, Bronchocela celebensis Gray, 1845 (Reptilia: Agamidae) endemic to Sulawesi, Indonesia.

Bronchocela celebensis Gray, 1845 is one of the rarest species of the genus, known only from less than 20 museum specimens collected from northern Sulawesi. It is often confused with its similar congener, B. cristatella, which occurs widely throughout the Indonesian Archipelago and Peninsular Malaysia, except on the Sulawesi mainland. Here, we examine the morphology of B. celebensis based on 46 museum specimens including freshly collected individuals, and redescribe the species based on the holotype (by monotypy). We studied the characters of B. celebensis with morphometric comparison to its allopatric congener B. cristatella from the adjacent islands of southern Sulawesi in Indonesia. Based on the current distribution pattern and the apparent threats, we update the conservation status of B. celebensis using the IUCN Red List Criteria and propose that it be considered as a Vulnerable (VU) species endemic to Sulawesi.

Systematics and distribution of Lankascincus fallax (Peters, 1860) (Reptilia, Scincidae), an endemic litter-skink from Sri Lanka.

Lankascincus fallax is an endemic, but widespread species of skink distributed throughout Sri Lanka, including all bioclimatic zones (elevations from 0 to 1,200 m a.s.l.). After thoroughly comparing morphology and morphometry between populations in different bioclimatic zones, we recognize it as a single morphospecies. We revise the systematics of Lankascincus fallax based on molecular and morphological data providing a comprehensive re-description of the adult syntype collected from either Ratnapura or Trinkomalee (sic), Sri Lanka. We provide the first-ever constructed phylogeny of Lankascincus representing five species (out of nine) based on GenBank data. In addition, we examined all the type specimens of the two synonymized species, Sphenomorphus rufogulus and Lankascincus deraniyagalae. We also provide a comprehensive discussion on the distribution of L. fallax.

Apparent coordinated and communal hunting behaviours by Erabu sea krait Laticauda semifactiata.

Opportunistic observations of Erabu sea kraits (Laticauda semifaciata) provide evidence that this species undertake a novel foraging tactic; coordinated communal hunting. Erabu sea kraits prey on cryptic fish species in highly complex reef habitats. Intra- and interspecific cooperative hunting strategies may increase chances for all members of the hunting party to encounter and capture prey in these complex habitats. Here, we observed 52 instances of communal hunting by Erabu sea kraits with conspecifics and other predatory fishes at recreational dive sites in Southern Lombok, Indonesia. These observations highlight the potential higher cognitive capacity of sea kraits to coordinate activities around communal hunting events.

A review of the genus Bronchocela Kaup, 1827 (Reptilia: Agamidae) in the Nicobar Archipelago with the description of two new species.

Species of the agamid genus Bronchocela Kaup, 1827 in the Andaman and Nicobar Islands are reassessed based on newly collected specimens from different parts of the Nicobar Archipelago. An assessment based on morphology and distribution of the identified groups reveal two new, unnamed populations, one allied to B. cristatella and the other allied to B. danieli. These two populations are described as new species, and Bronchocela cristatella is redescribed based on Sundaic specimens. The remaining species, B. danieli and B. rubrigularis are redescribed. Distributions of all of these four species are mapped and recommendations on their conservation status are suggested.

Molecular phylogeny reveals distinct evolutionary lineages of the banded krait, Bungarus fasciatus (Squamata, Elapidae) in Asia.

The banded krait, Bungarus fasciatus is a widespread elapid snake, likely to comprise several distinct species in different geographic regions of Asia. Therefore, based on molecular phylogenetics and comparative morphology data, we present an overview of the systematic composition of the species to delimit potential biogeographic boundaries. Our phylogenetic analyses, based on four mitochondrial genes, reveal the existence of at least three evolutionary lineages within B. fasciatus, corresponding to Indo-Myanmar, Sundaic and eastern Asian lineages. We are convinced that there are at least three taxonomic entities within the nomen B. fasciatus and restrict the distribution of B. fasciatus sensu stricto to the Indo-Myanmar region. We also provide additional natural history data of the taxon from eastern India. Finally, we advocate further studies to establish the degree of reproductive isolation among these diverging evolutionary lineages and to reassess the systematic status of this species complex especially the Sundaic and eastern Asian lineages.

Taxonomy and distribution of a common arboreal lizard, Bronchocela jubata Dumril amp; Bibron, 1837 (Reptilia: Agamidae), with designation of its lectotype from Java, Indonesia.

Bronchocela jubata Dumril and Bibron, 1837 is one of the commonest species of the genus, known mostly from Java Island and southern parts of Sumatra. It is rare in Bali and Borneo. The juveniles are often confused with its morphologically similar congener, B. cristatella, which occurs widely throughout the Indonesian Archipelago and Peninsular Malaysia. We examined the morphology of B. jubata based on museum specimens including its two available syntypes, and redescribed the species based on the lectotype designated herein. We highlight the characters of B. jubata with a morphometric comparison to its sympatric congener B. cristatella from Java Island, Indonesia. Based on the current distribution pattern and the apparent threats, we update the conservation status of B. jubata using IUCN Red List Criteria, and propose that it be considered as a species of Least Concern (LC), endemic to the Greater Sundaic Islands.

Taxonomy, distribution, and conservation status of a rare arboreal lizard, Bronchocela hayeki (Mller, 1928) (Reptilia: Agamidae) from northern Sumatra, Indonesia.

Bronchocela hayeki (Mller, 1928) is one of the rarest species of the genus, known only from a handful of museum specimens from five locations in North Sumatra, and often confused with its similar congener, B. cristatella, which occurs widely throughout the Indonesian Archipelago and Peninsular Malaysia. Here, we examined the morphology of B. hayeki based on museum specimens, and redescribe the species based on a freshly collected series near the type locality, as the condition of its neotype is not in a good state. We studied the characters of B. hayeki with a morphometric comparison to its sympatric congener B. cristatella and allopatric congener, B. jubata from Sumatra Island, Indonesia. Based on the current distribution pattern and the apparent threats, we update the conservation status of B. hayeki using IUCN Red List Criteria and propose that it be considered as an Endangered (EN) species endemic of northern Sumatra including Aceh. We also provide a key to the recognized Bronchocela species, based on examined material and literature.

Taxonomy and predicted distribution of a rare Indian skink, Eutropis innotata (Blanford, 1870) (Reptilia: Scincidae) with the redescription of its holotype.

We examined the holotype of Euprepes innotatus Blanford, 1870 which was presented to the Natural History Museum, London (NHMUK) by Blanford himself, and is redescribed herein. Based on the morphological similarity, we placed Eutropis innotata within the E. carinata group (contra Blanford, 1870), as it is closely allied to E. dissimilis and E. carinata in morphological and morphometric traits. Based on the current distribution pattern, we conducted Species Distribution Modelling using the Maximum Entropy algorithm and the distribution range of this species was predicted to be wider than the currently known limits within the south-central parts of the Deccan plateau. Furthermore, we updated the conservation status of E. innotata using the criteria of the IUCN Red List, and suggested it be considered as a species of Least Concern.

Morphological and molecular description of Armillifer moniliformis larvae isolated from Sri Lankan brown palm civet (Paradoxurus montanus).

We report Armillifer moniliformis species infecting the endemic Sri Lankan brown palm civet (Paradoxurus montanus) from the Knuckles Range Forest Conservation Area, Sri Lanka. Larval stages of A. moniliformis were found during the postmortem of three civet cats found dead. Morphological studies were done by a light microscope and a scanning electron microscope (SEM). Histopathological examination was conducted using tissue samples obtained from the liver. For the molecular analysis, DNA was extracted from the isolated third-stage larvae. The NADH dehydrogenase subunit 5 (ND5) and the second internal transcribed spacer region (ITS-2), a portion of the large subunit nuclear ribosomal DNA (28S), a portion of 18S ribosomal rRNA gene (18S), and cytochrome c oxidase subunit 1 gene (COX1) were amplified using polymerase chain reaction (PCR). Excysted third-stage larvae were observed in the lungs, omentum, the pleural cavity, the abdominal cavity, and the surface of the spleen and the pericardium. Around 88 third-stage larvae were isolated from three civet cats. First-stage larvae in the liver were surrounded by outer fibrous layer over the inner germinal layer and filled with clear fluid. Slight hemorrhage, leukocyte infiltration, and mild hepatocellular degeneration in the liver were observed. The SEM examination indicated the unique oral apparatus comprises the oval-shaped mouth opening in between two pairs of curved, retractile hamuli. The sequences obtained for ND5, ITS-2, 28S, 18S, and COX1 were 301, 382, 325, 414, and 644 bp in length respectively. Morphology, sequence similarity search, sequence alignment, and phylogenetic analysis identified this parasite as A. moniliformis.

High Prevalence of Lifestyle Factors Attributable for Oral Cancer, and of Oral Potentially Malignant Disorders in Rural Sri Lanka

Background: Oral Cancer is a major public health problem in most of the South East Asian countries including Sri Lanka. Use of tobacco in the form of smokeless tobacco and smoking, use of alcohol and betel quid chewing are the major contributory factors for causation oral cancer. The aim of this study was to investigate the prevalence of lifestyle factors responsible for causation of oral cancer and Oral Potentially Malignant Disorders (OPMD) in the Sabaragamuwa province of Sri Lanka. Methods: A cross-sectional community based study was conducted in Sabaragamuwa province by interviewing, then conducting an oral examination, on 1029 subjects over 30 years of age, over a one year period from November 2006. The study protocol included an interviewer-administered questionnaire to gather socio-demographic factors, recording of habits that included areca/betel chewing, smoking, and alcohol consumption. A three-day food diary was obtained, particularly to assess the consumption of tea, fruits and vegetables. The weight and height of residents was taken for calculation of Body Mass Index (BMI). Results: One hundred and two individuals with one or more OPMD were detected among these 1029 subjects. The prevalence of OPMD, weighted according to the estate sector and gender, was estimated as 11.3%. The prevalence of daily betel quid chewing in this study was 53.8%: 15.7% without tobacco and 47.4% with tobacco. The prevalence of individuals who reported consumption of alcohol at least weekly was 13.4%. A significant minority, 31.7%, were under nourished, with a BMI < 18.5. Forty six percent of the males practiced combined habits of betel quid chewing, smoking and regular use of alcohol. Conclusions: This study discloses high prevalence of OPMD and of lifestyle factors for oral cancer in these communities. There is an urgent need for a comprehensive strategy to control the use of tobacco, betel quid chewing and alcohol for prevention of oral cancer.

Metastatic spine tumor surgery: does perioperative blood transfusion influence postoperative complications?

BACKGROUND: The question of independent association between allogeneic blood transfusion (ABT) and postoperative complications in cancer surgeries has been controversial and remains so. In metastatic spine tumor surgery (MSTS), previous studies investigated the influence of ABT on survival, but not on postoperative complications. We aimed to evaluate the influence of perioperative ABT on postoperative complications and infections in patients undergoing MSTS. STUDY DESIGN AND METHODS: This retrospective study included 247 patients who underwent MSTS at a single tertiary institution between 2005 and 2014. The outcome measures were postoperative complications and infections within 30 days after MSTS. Multivariate logistic regression analyses were performed to assess influence of blood transfusion on the outcomes after adjusting for potential confounders. RESULTS: Of 247 patients, 133 (54%) received ABT with overall median (range) of 2 (0-10) units. The adjusted odds of developing any postoperative complication was 2.27 times higher in patients with transfusion (95% confidence interval [CI], 1.17-4.38; p = 0.01) and 1.24 times higher odds per every unit increase in blood transfusion (95% CI, 1.05-1.46; p < 0.01). Exposure to blood transfusion also increased the odds of having overall postoperative infections (odds ratio, 3.58; 95% CI, 1.15-11.11; p = 0.02) and there were 1.24 times higher odds per every unit increase in transfusion (95% CI, 1.01-1.54; p = 0.04). CONCLUSIONS: This study adds evidence to the literature implicating ABT to be influential on postoperative complications and infections in patients undergoing MSTS. Appropriate blood management measures should, therefore, be given a crucial place in the care of these patients so as to reduce any putative effect of blood transfusion.

Systematics of Eutropis rugifera (Stoliczka, 1870) (Squamata: Scincidae) including the redescription of the holotype.

Eutropis rugifera has long been identified as a widespread species complex distributed in Nicobar, Peninsular Malaysia, Greater Sundaic Islands, Bali, Sulawesi and the Philippines. This skink was described by Stoliczka in 1870 from Nicobar Island based on a single specimen (holotype by monotypy). Later, Peters (1871), Bartlett (1895) and Werner (1896) described three more species which were morphologically similar to Euprepes percarinatus (from Java), Mabuia rubricollis (Borneo) and M. quinquecarinata (Sumatra) respectively, which are currently considered junior objective synonyms of Eutropis rugifera. We examined all the available synonym types and voucher specimens of Eutropis rugifera deposited at several museums. A morphological examination of the types of this species and mtDNA analysis (584 bp of 16S rRNA) of the samples from different biogeographic regions revealed that Eutropis rugifera from Nicobar Island, Bali Island, and Bawean Island are composed of a monophyletic species. However, the taxonomic status of the above population requires further clarification, and the population in Bawean Island may represent a cryptic species. Finally, we provide a complete redescription of E. rugifera based on its holotype.

Active safety monitoring of measles-mumps-rubella vaccine in the National Immunisation Programme of Sri Lanka

Objectives: This study was designed to report incidence and characteristics of selected adverse events following immunisation which have consistent causal association (AEFIc) with Measles-Mumps-Rubella (MMR) vaccination given at the age of one year in the National Immunisation Programme of Sri Lanka. Methods: The data presented here were obtained from a cohort event monitoring study. It was carried out in the Jaffna Regional Directorate of Health Services area from November 2012 to December 2014. A representative sample of 3002 infants who received MMR immunisation were actively followed up for adverse events (AE) using over the phone interviews, self-reporting, and home or hospital visits up to 45 days. All AEs were reviewed by two investigators independently in two step-wise processes to detect the AEFIc. Seven AEFIc were detected using standard case definitions and onset time limit criteria. They were subjected to further analysis to describe the incidence rates and characteristics. Results: Of the 2398 (80%) infants who completed follow up of 45 days, 1321 infants experienced 2621 AEFI. Of them 209 were classified as AEFIc. Incidence of AEFIc was 87/ 1000 immunisation. They were mainly nonserious and resolved completely. There were no fatal or life threatening AEFIs. Incidence per 1000 immunisations; allergic reactions 0.83, injection site reactions 4.58, fever100.4° F or lasting more than  3 days 9.59, macular papular rash 2.92, parotitis 2.92 and generalised convulsions 1.25. Conclusions: The MMR vaccine used in NIP of Sri Lanka had low incidence of AEFIc and were mainly non-serious in nature.

The Re-discovery of live populations of Cnemaspis tropidogaster (Boulenger, 1885) (Sauria, Gekkonidae) from Sri Lanka after 120 years.

Gonatodes kandianus var. tropidogaster was described by Boulenger (1885) with only "Ceylon" (=Sri Lanka) as its locality. This taxon was later assigned to the genus Cnemaspis and then recorded from many different parts of the country. Misleading taxonomic publications and muddled nomenclatural issues has since rendered its taxonomic position unclear. Recent studies have revealed, however, that C. tropidogaster is a species complex, and the species and its types have been redescribed. Unfortunately, no live populations of this species have been recorded until now. Here we report the rediscovery of live populations of this species 120 years after its last collection date records. C. tropidogaster was rediscovered from a low elevation (50-80 m asl.) of the wet zone of Sri Lanka. The rediscovered population was attributed to C. tropidogaster on the basis of a suite of matching morphometric and meristic characters that distinguish C. tropidogaster from other Sri Lankan Cnemaspis.

Safety of live attenuated Japanese encephalitis vaccine given at the age of 9 months in National Immunisation Programme of Sri Lanka.

OBJECTIVES: This study was designed to describe the safety profile of the single dose live attenuated Japanese encephalitis vaccine (LJEV) SA-14-14-2 given at the age of 9 months in the National Immunisation programme of Sri Lanka. METHODS: cohort event monitoring (CEM) was conducted in the Jaffna district during November 2012 to January 2015. A representative sample of 3041 infants who received the LJEV at the age of 9 months was followed up actively over telephone interviews on days 1, 3, 14, 30 and 45 for adverse events (AE). Parents were encouraged to self-report in between these interviews. When an AE is notified, further clinical information was obtained through in-depth interviews and home/hospital visits to determine as an adverse event following immunisation (AEFI). Investigators independently reviewed each AEFI for consistent causal association with LJEV according to WHO causality assessment. RESULTS: Of the 2878 (94%) infants who completed the follow up of 14 days, 911 (32%) experienced 1423 AEFIs. Of them, 376 (26%) were identified as AEFI with consistent causal association to LJEV (AEFIc). Irritability (53/ 1000 doses administered) and fever ≥100.4° F (46/1000 doses administered) accounted for 41% and 35% of AEFIcrespectively. Majority of AEFI (940) were identified as inconsistent as there were alternate causes. Nineteen AEFIc in 14 infants were classified as serious since they led to hospitalisation. Of the 2392 (79%) infants who completed 45 days follow up, 1022 experienced 1804 AEFI during 15-45 days. Only 20 were identified as AEFIc. There were no reported fatal or life threatening AEs. CONCLUSIONS: LJEV administered to infants at 9 months was devoid of any significant safety concerns as most of the AEFIs were non-serious and resolved completely. CEM is a useful method for AEFI surveillance.

Taxonomy of two endemic Indian skinks, Eutropis bibronii (Gray, 1838)and E. nagarjunensis (Sharma, 1969) (Reptilia: Scincidae), including redescriptions of their types.

Tiliqua bibronii was described by J.E. Gray in December, 1838 based on two syntypes (MNHN-RA 2940, 7076), but the details for locality was missing. These syntypes are currently housed at the Muséum national d'Histoire naturelle, Paris, France (MNHN-RA). The same species (based on the same type specimens) was described by A.M.C. Duméril & G. Bibron in November, 1839 nearly one year after Gray's publication. As such, Gray's publication must therefore be given priority. Another species, Euprepis trilineatus, from Madras, Tamil Nadu, India, was described by Gray in 1846, and it is morphologically similar to E. bibronii. Later, Boulenger (1885) synonymised it with E. bibronii. Eutropis bibronii has subsequently been recorded from other parts of India and Sri Lanka by various authors. Many years later, a closely related species, Mabuya nagarjuni (sic) Sharma, 1969, was described from Andhra Pradesh, India, based on two specimens (a holotype and a paratype) housed at the Zoological Survey of India, Kolkata (ZSI). Here we make a correction for the species epithet as "nagarjunensis" which should be a toponym, not a patronym. Among the skink collections at the Natural History Museum, London (BMNH), ZSI, and MNHN-RA we found E. bibronii specimens collected from various locations in India, but we were unable to find any specimens from Sri Lanka. Based on morphological evidence, E. bibronii represents a single, fairly widespread, species which has to be considered endemic to India. Although, recent phylogenetic studies reveal a distinct genetic divergence between E. bibronii and E. nagarjunensis, both species are morphologically very similar to each other. Here, we examine the morphology of E. nagarjunensis based on the ZSI specimens. A comprehensive comparison between the syntypes of E. bibronii and Euprepis trilineatus confirms that the latter nomen is a junior synonym of the former. The original description of E. bibronii is extremely concise and lacks most of the important diagnostic characters, so here we provide a comprehensive redescription of the species based on the examination of its syntypes.

Resurrection of Pseudorabdion torquatum (A.M.C. Duméril, Bibron & A.H.A. Duméril, 1854), a former synonym of P. longiceps (Cantor, 1847) (Colubridae: Calamariinae) from Sulawesi, Indonesia.

The colubrid snake species Pseudorabdion torquatum is resurrected from the synonymy of P. longiceps. Out of the three syntypes, only two were located and examined at Muséum national d'Histoire naturelle, Paris, France (MNHN-RA). Pseudorabdion torquatum differs from P. longiceps in having a larger SVL (227.0 mm vs. 132.0-193.0 mm in males); higher number of ventral in males, 141 (vs. 127-139); lower number of ventrals in females, 137 (vs. 139-145); lower number of subcaudals in both sexes, 12-17 (vs. 17-30); and six supralabials (vs. five). Pseudorabdion torquatum is thus regarded as a valid and endemic species to Sulawesi. The species is here redescribed and a lectotype is designated. Furthermore we provide an English translation of the original description of Rabdion torquatum which was originally written in French. Thus, besides unconfirmed records of P. longiceps from Sulawesi, there is a single known congener from that island, P. sarasinorum.

On the resolution of a long standing issue surrounding the holotype of Cnemaspis podihuna Deraniyagala, 1944 (Reptilia: Gekkonidae).

The number of species in the genus Cnemaspis Strauch, 1887 has grown rapidly, and it currently comprises more than 100 species (Grismer et al. 2014; Amarasinghe et al. 2015). The Sri Lankan endemic and vulnerable day-gecko Cnemaspis podihuna Deraniyagala, 1944 (Ministry of the Environment 2012) was first described by Deraniyagala from the Lahugala-Maha Oya, Eastern Province on the basis of one holotype and four paratypes [incorrectly reported as three paratypes by Karunarathna et al. 2010]. There had been no further collections or sightings made of this species until Wickramasinghe (2000) rediscovered the species from Koslanda in the Badulla District (National Museums of Sri Lanka, Colombo, NMSL RG 21a-e). Wickramasinghe and Munindradasa (2007) collected a further four specimens (NMSL 20061001-4) around the type locality. Recently, Sri Lankan members of the day-gecko genus Cnemaspis were reviewed and redescribed morphologically by two groups of researchers: Wickramasinghe and Munindradasa (2007) and Manamendra-Arachchi et al. (2007). The former group considered the holotype lost. Therefore, they designated a neotype plus syntypes for C. podihuna. This action was invalidated by Pethiyagoda (2007) following the International Code of Zoological Nomenclature (ICZN 1999).

Drying kinetics and mathematical modeling of hot air drying of coconut coir pith.

Drying kinetics of coir pith was studied and the properties of compressed coir pith discs were analyzed. Coir pith particles were oven dried in the range of temperatures from 100 to 240 °C and the rehydration ability of compressed coir pith was evaluated by finding the volume expansion. The optimum drying temperature was found to be 140 °C. Hot air drying was carried out to examine the drying kinetics by allowing the coir pith particles to fluidize and circulate inside the drying chamber. Particle motion within the drying chamber closely resembled the particle motion in a flash dryer. The effective moisture diffusivity was found to increase from 1.18 × 10(-8) to 1.37 × 10(-8) m(2)/s with the increase of air velocity from 1.4 to 2.5 m/s respectively. Correlation analysis and residual plots were used to determine the adequacy of existing mathematical models for describing the drying behavior of coir pith. The empirical models, Wang and Singh model and Linear model, were found to be adequate for accurate prediction of drying behavior of coir pith. A new model was proposed by modifying the Wang and Singh model and considering the effect of air velocity. It gave the best correlation between observed and predicted moisture ratio with high value of coefficient of determination (R(2)) and lower values of root mean square error, reduced Chi square (χ(2)) and mean relative deviation (E%).

Taxonomy and natural history of Eutropis beddomei (Jerdon, 1870) (Reptilia: Scincidae), including a redescription of the holotype.

Euprepes beddomei was described by Jerdon (1870) from "Mysore" (Karnataka State, India). Simultaneously, Euprepes (Tiliqua) septemlineatus, which is morphologically similar to E. beddomei, was described by Blanford (1870) based on a single specimen collected from the Ganga River Valley, Southeast Berar, Madhya Pradesh, India. Smith (1935) synonymised the latter species (published in September, 1870) with Euprepes beddomei which in turn was published earlier (March, 1870). Jerdon's publication should therefore be given priority. A comprehensive comparison between the holotypes of the above two species confirms that E. septemlineatus is a junior synonym of E. beddomei. Based on morphological characters, Eutropis beddomei is here clearly identified and can be considered a widespread species in India and Sri Lanka. The original description of E. beddomei is very short and lacks a description containing most of the important diagnostic characters; hence, we hereby provide a comprehensive description of the species based on the examination of its holotype.
