Four new species of amblyceran chewing lice of the genus Myrsidea Waterston, 1915 are described from hosts of the babbler families Leiothrichidae, Paradoxornithidae and Timaliidae in China. They are Myrsidea attenuata n. sp. from Garrulax maesi maesi (Oustalet, 1890), Myrsidea zhangae n. sp. from Ianthocincla berthemyi (Oustalet, 1876), Myrsidea liopari n. sp. from Lioparus chrysotis amoenus (Mayr, 1941) and L. chrysotis swinhoii (Verreaux, 1871), and Myrsidea suthorae n. sp. from Suthora verreauxi verreauxi Sharpe, 1883. A checklist of host-louse associations for identified and unidentified Myrsidea species known from babblers is provided.Agricultural soils and open fields from Western Uttar Pradesh (India) were surveyed to determine the presence of entomopathogenic nematodes. From the entomopathogenic nematodes isolated, Heterorhabditis isolates were selected and further characterized using morphological, morphometrical and molecular approaches. The results showed that three isolated nematodes were Heterorhabditis bacteriophora and were associated with Photorhabdus laumondii subsp. clarkei bacteria, while the rests were identified as Heterorhabditis indica. The biocontrol potential of H. bacteriophora against three agricultural pests was evaluated. Nematode infectivity experiments showed that the nematode isolates DH7 and DH8 were highly pathogenic against cotton bollworm (Helicoverpa armigera) and tobacco cutworm (Spodoptera litura), and less pathogenic against white grub (Holotrichia serrata) larvae. This study sets the basis for establishing new biocontrol agents to be used in pest management programs in India.We describe seven species of Pilargidae from the coast and deep sea (300-1400 m deep) of southeastern Brazil, belonging to the genera Ancistrosyllis McIntosh, 1878, Cabira Webster, 1879, Glyphohesione Friedrich, 1950, Hermundura Müller, 1858, and Pilargis Saint-Joseph, 1899. Of those, two are new species (Glyphohesione campensis sp. nov. and Pilargis falconae sp. nov.) and two are new records of Ancistrosyllis for Brazil. Glyphohesione campensis sp. nov. is distinguished from its congeners by fewer neurochaetae, the anteriormost appearance of first notopodial spines, and intermediate relative length of dorsal and ventral cirri. Pilargis falconae sp. nov. is diagnosed by the presence of parapodial glands from the first chaetiger on the dorsal surface and from the sixth chaetiger on the ventral surface; and neurochaetae smooth capillaries and limbates with unidentate tips. Keys to pilargid species reported from, or likely to occur in, Brazilian waters are provided.The taxonomy of the Asian tree frog genus Feihyla has been in a state of flux ever since its proposal in 2006. Allocation of species to Feihyla remains confusing, particularly with respect to the closely related genus Chirixalus (formerly Chiromantis sensu lato). At the same time, several Chirixalus species are known only from cursory descriptions and remain poorly studied. In this study, we review the systematics of the genus Feihyla and clarify the generic placement of its members along with all other species currently assigned to Chirixalus. Based on integrative evidence gathered from new collections, examination of types and original descriptions, morphological comparisons, phylogenetic relationships inferred from a multi-gene (three mitochondrial + two nuclear) 1,937 bp dataset, as well as reproductive modes including egg-laying, nesting behaviour, and clutch morphology, our results show that the six species formerly attributed to Feihyla represent three morphologically and phylogenetically distinct grou. [https://www.selleckchem.com/products/z-vad(oh)-fmk.html click here] In addition, we report the first member of the tree frog family Rhacophoridae from the Andaman Islands of India-Rohanixalus vittatus, along with description of its male advertisement call, reproductive behaviour including parental care by the female, and larval morphology. Extended distributions are also provided for Rohanixalus species across Northeast India. The study further reveals the presence of potentially undescribed diversity in the new genus. Altogether, the revised classification and novel insights presented herein will facilitate a better working taxonomy for four phylogenetically distinct but morphologically related groups of Old World tree frogs.Roger (Ruggero) Verity published Phoenicurusia as a subgenus of Lycaena Fabricius, on p. 21 of vol. 2 of Farfalle Diurne d'Italia (1943), since in the male genitalia the falces were bent like an acute elbow after one-quarter of their length, rather than smoothly curved as they are in species of the subgenus Lycaena. Verity contextually designated Polyommatus phoenicurus Lederer, 1870 (Locus Typicus [LT] 'Hadschyabad' [N. Iran]) as the Type Species [TS] of Phoenicurusia and described the male genitalia of phoenicurus Lederer, 1870, "razza" scintillans Christoph, 1887, labelled as from Germab (Askhabad [Turkmenistan]), and those of Polyommatus dimorphus Staudinger, 1881, labelled as from Passo Taldyk [Kyrgyzstan Alai Mts]. Although Verity included both species in his new subgenus, he also highlighted an important difference existing between them, since, contrary to those of dimorphus, the genitalia of phoenicurus were 'enormous' with respect to the size of the butterfly. Both the aedeagus and the valvae were extremely elongate, much more than those of dimorphus and the latter were terminally toothed.Brescovit (1993), in the revision of the genus Hibana, described H. talmina, based on males from Venezuela, Colombia, Guyana and northern Brazil. Subsequently, Brescovit Lise (1993) described its female, in an attempt to associate with the male, based on specimens collected in Dominica and Trinidad. Unfortunately, there was no justification for this mating. Recently Galvis et al. (2019) collected several couples of Hibana talmina in mangrove forests in some surrounding areas of Cartagena (Bolívar, Colombia), during a study of predation of crabs on these spiders. The detailed study of these couples showed that there was a wrong mating by Brescovit Lise (1993) and this is corrected here. The original distribution is updated, with the exclusion of Dominica. The females previously assigned to H. talmina are treated here as Hibana labonita sp. nov., which is diagnosed in relation to the other species of Hibana.
