ABSTRACT
Abstract We describe a new species of the genus Podanotum Torres & Johnson, 1996, Podanotum pajaten Farfán, Cerdeña & Bálint sp. nov. from northern Peru, associated with the Andean treeline ecotone adjacent to cloud forest and wet grassland at 3200 m above sea level. Description of this new species is based on one female adult and is distinguishable from its congeners by the combination of the following morphological characters: dorsal wing pale blue, forewing discoidal line present on ventral side, hindwing tailed, and ostium bursae distally toothed. Podanotum pajaten sp. nov. is separated geographically from the closest spatial species, P. glorissimum Bálint & Wojtusiak, 2002, by approximately 100 km to the south, and represents the second species described for Peru. An identification key to all known species of Podanotum is provided, stating their distributions by country.
Resumen Se describe una nueva especie del género Podanotum Torres & Johnson, 1996, Podanotum pajaten Farfán, Cerdeña & Bálint sp. nov. del norte de Perú, asociada al ecotono andino entre bosque nublado y pastizal húmedo a 3,200 metros de altitud. La descripción de esta nueva especie está basada en una hembra adulta que se distingue de sus congéneres por la combinación de los siguientes caracteres morfológicos: vista dorsal de las alas de color azul pálido, línea postdiscal del ala anterior presente en vista ventral, cola corta en ala posterior, y parte distal del ostium bursae dentada. Podanotum pajaten sp. nov. está separada geográficamente de la especie espacialmente más cercana, P. glorissimum Bálint & Wojtusiak, 2002, por aproximadamente 100 km hacia el sur, y representa la segunda especie descrita de Perú. Una clave de identificación es presentada para todas las especies conocidas de Podanotum, con indicación de los países de ocurrencia.
ABSTRACT
Resumen La estación científica de Wayqecha se sitúa en el departamento de Cusco, en el sudeste de Perú, a una altitud de 2900 m (13°10.506'S - 71°35.210'W). En esta estación, encontramos una oruga de Leptotes callanga (Dyar, 1913) (Lepidoptera : Lycaenidae : Polyommatinae), alimentándose de flores de Genista monspessulana (L.) L.A.S. Johnson (Fabaceae), una planta no nativa, de origen mediterráneo. La crianza permitió obtener una hembra adulta de L. callanga. La oruga en el último estadio y la crisálida se describen e ilustran. Se comenta la adaptación de esta especie a una nueva planta.
Abstract The Wayqecha scientific station is located in the department of Cusco, in southeas- tern Peru, at an altitude of 2900 m (13°10.506'S - 71°35.210'W). In this station, we found a caterpillar of Leptotes callanga (Dyar, 1913) (Lepidoptera : Lycaenidae : Polyommatinae), consuming flowers of Genista monspessulana (L.) L.A.S. Johnson (Fabaceae), a non- native plant of Mediterranean origin. The breeding allowed to obtain a female L. callanga. Last instar larvae and pupa are described and illustrated. Leptotes callanga adaptation to this new plant is commented.
ABSTRACT
En la estación científica de Villa Carmen, situada cerca de Pillcopata, Cusco, Perú (S 12°53.687' - W 71°24.232', 533 m), encontramos orugas de Michaelus phoenissa (Hewitson, 1867) (Lycaenidae), consumiendo flores de Senna alata (L.) Roxb. (Fabaceae). La mayoría de las orugas se encontraban en el último estadio (entre 1 y 1.5 cm de longitud), no visibles a primera vista, ya que se alojaban en las flores no abiertas. La crianza permitió obtener cuatro adultos, dos hembras y dos machos y ningún parasitoide. Se compara las plantas hospederas de M. phoenissa con otras especies hospederas del genero de Michaelus Nicolay, 1979.
In Villa Carmen, a scientific station near Pillcopata, Cusco, Peru (S 12°53.687' - W 71°24.232', 533 m), we found caterpillars of Michaelus phoenissa (Hewitson, 1867) (Lycaenidae) consuming flowers of Senna alata (L.) Roxb. (Fabaceae). The caterpillars were mostly last instars (between 1 and 1.5 cm in length). They were not visible at first sight because they lodged in unopened flowers. We reared two female and two male adults. None of the immature stages was parasitized. We compare the food plants of M. phoenissa with those of others species of Michaelus Nicolay, 1979.
ABSTRACT
The wide range of morphological variations in the "loxurina group" makes taxa identification difficult, and despite several reviews, serious taxonomical confusion remains. We make use of DNA data in conjunction with morphological appearance and available information on species distribution to delimit the boundaries of the "loxurina" group species previously established based on morphology. A fragment of 635 base pairs within the mtDNA gene cytochrome oxidase I (COI) was analysed for seven species of the "loxurina group". Phylogenetic relationships among the included taxa were inferred using maximum parsimony and maximum likelihood methods. Penaincisalia sigsiga (Bálint et al), P. cillutincarae (Draudt), P. atymna (Hewitson) and P. loxurina (C. Felder & R. Felder) were easily delimited as the morphological, geographic and molecular data were congruent. Penaincisalia ludovica (Bálint & Wojtusiak) and P. loxurina astillero (Johnson) represent the same entity and constitute a sub-species of P. loxurina. However, incongruence among morphological, genetic, and geographic data is shown in P. chachapoya (Bálint & Wojtusiak) and P. tegulina (Bálint et al). Our results highlight that an integrative approach is needed to clarify the taxonomy of these neotropical taxa, but more genetic and geographical studies are still required.
