Two new species of the genus Aphelocheirus (Hemiptera: Heteroptera: Aphelocheiridae), A. longlingensis sp. nov. from Yunnan and A. motuoensis sp. nov. from Xizang (Tibet) Autonomous Region are described in this paper. A. similaris Polhemus & Polhemus, 1989, A. nawae Nawa, 1905 and A. tuberculipes Zettel & Tran, 2009 are reported from China for the first time. A key to Chinese species of Aphelocheirus is given. Dorsal habitus photographs of the species are provided, accompanied by illustrations of male genitalic structures, inner projection and female ventral aspect of posterior abdominal segments.
This paper provides the description of a new species, Aphelocheirus menglaensis sp.nov. from Yunnan Province. A. gularis Horváth, 1918 and A. inops (Horváth, 1918) are reported from China for the first time. We also reviewed A. ellipsoideus Liu & Ding, 2005, include its macropterous forms and brachypterous female. Dorsal habitus photographs of the new species and A. ellipsoideus are provided and are accompanied by illustrations of male genitalic structures of both species and the ventral aspect of posterior abdominal segments of the female of only the new species.
The complete mitochondrial genome (mt-genome) of Nepa hoffmanni has been reported in this study. This mitochondrial genome is 15 774 bp long, with an A + T content of 72.04%, containing the typical 37 genes (13 protein-coding genes (PCGs), 22 transfer RNA genes, and two ribosomal RNA genes) and a control region. All genes are arranged in the same gene order as most other known heteropteran mt-genome. This is the second completely sequenced mt-genome from the family Nepidae of Nepomorpha. Bayesian analyses were performed using the mt-genome of Nepa hoffmanni and its relatives, including 17 taxa, showing a reasonable placement of Nepa hoffmanni.
The three species of Nerthra Say, 1832 (Hemiptera: Heteroptera: Gelastocoridae) occurring in China are reviewed. Dorsal habitus photographs of the two species, Nerthra
asiatica (Horváth, 1892) and Nerthra
indica (Atkinson, 1889), are provided, accompanied by illustrations of male genitalic structures and female ventral aspect of posterior abdominal segments. The male of Nerthra
asiatica is recorded and reviewed for the first time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
