Report on antennal sensilla of Aphelocheirus ellipsoideus (Hemiptera, Heteroptera, Aphelocheiridae).

The comparative morphology study on antennal sensilla of Aphelocheirus ellipsoideus from the family Aphelocheiridae, carried out with the use of a scanning electron microscope, is provided. Five main types of mechano-, chemo-, and thermo-hygroreceptive sensilla with two subtypes of sensilla basiconica were found and described on their surface, including sensilla trichodea, campaniformia, basiconica, ampullacea, and plate-like. Antennal sensilla of A. ellipsoideus on macropterous and brachypterous forms were different.

Notes on some toad bugs from China (Hemiptera, Heteroptera, Gelastocoridae).

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.

A new species and notes on the genus Aphelocheirus (Hemiptera: Heteroptera: Aphelocheiridae) from China.

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 checklist and a key to the species of Naucoridae of China are given. Dorsal habitus photographs of the species are provided, accompanied by illustrations of male genitalic structures and female ventral aspect of posterior abdominal segments (new species). 

Two new species and three new records of the genus Aphelocheirus (Hemiptera: Heteroptera: Aphelocheiridae) from China.

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.
