ABSTRACT
BACKGROUND: The myriapod fauna of China is still poorly known and very little attention has been paid to the study of Lithobiomorpha, with only 100 species and subspecies known from the country. Altogether, 11 species of subgenusMonotarsobius have been recorded from China, but only two of them have been reported from Hebei Province. Herein, a new species recently discovered in the Hebei Province, China, is described and illustrated. NEW INFORMATION: A new lithobiids species Lithobius (Monotarsobius) tetrasulcus sp. n. is described and illustrated from Hengshui Lake National Nature Reserve, Hebei Province, China. The new species is compared with Lithobius (Monotarsobius) crassipes Koch, 1862 from Taiwan, China. It can be easily distinguished from congeners by having a longitudinal groove on the dorsal side of the femur and tibia of the male legs 14 and 15, only having a posterior spine on the dorsal side of femur of legs 12-15, lacking robust spines lying dorsally on the external margin on the second article of the female gonopods and the third article of the female gonopods having a bidentate apical claw.
ABSTRACT
BACKGROUND: The myriapod fauna of China is still poorly known and very little attention had been paid to the study of Lithobiomorpha, with only 100 species/subspecies hitherto known from the country, among which are only seven species of Hessebius. Here we are describing a new species of the genus Hessebius. NEW INFORMATION: A new lithobiid species, Hessebiuscrassifemoralis sp. nov., is described and illustrated from Hengshui Lake National Nature Reserve, Hebei Province, China. The new species is compared with H.luquensis Qiao, Qin, Ma, Su & Zhang, 2018 from Gansu Province, China. A key to Chinese species, based on adult specimens, is provided. Type specimens and other material are deposited in the School of Life Sciences, Hengshui University, Hengshui, China.
ABSTRACT
A polyphasic taxonomic study was undertaken to establish the status of a novel bacterium, designated strain WHSC-8T, which was isolated from soil of Hengshui Lake Wetland Reserve in Hebei province, northern China. Colonies of this strain were yellow and cells were rod-shaped, polar-flagellated and obligately aerobic, exhibiting negative Gram reaction. The strain was able to grow at 0-1 % (w/v) NaCl, pH 5-10 and 20-35 °C, with optimal growth occurring at pH 7.0 and 28 °C without NaCl. Chemotaxonomic data revealed that strain WHSC-8T possesses ubiquinone Q-10 as the predominant respiratory quinone, C18 : 1ω7c, C16 : 0 and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids, and sym-homospermidine as the major polyamine. Sphingomonadaceae-specific sphingoglycolipid was detected in the polar lipid patterns. The G+C content of the genomic DNA was 68.7âmol%. All of the above characters corroborated the assignment of the novel strain to the genus Sphingomonas. Strain WHSC-8T shared less than 97.0 % 16S rRNA gene sequence similarity with the type strains of other species of the genus Sphingomonas, except for Sphingomonas asaccharolytica DSM 10564T (97.5 %). The low DNA-DNA relatedness value and distinct phenotypic and chemotaxonomic characteristics distinguished strain WHSC-8T from closely related species of the genus Sphingomonas. Therefore, strain WHSC-8T represents a novel species of the genus Sphingomonas, for which the name Sphingomonas hengshuiensis sp. nov. is proposed. The type strain is WHSC-8T ( = KCTC 42455T = CCTCC AB 2015265T).
