Review of stick insects (Insecta: Phasmatodea) from Yintiaoling Nature Reserve of China, with description of two new species.

This is the first investigation of stick insect from the Yintiaoling National Nature Reserve, Chongqing of China. Totally seven species were collected. Four of them belong to the subfamily Clitumninae of Phasmatidae: Interphasma emeiense Chen & He, 2008, Paraentoria sichuanensis Chen & He, 1997, Parabaculum wushanense (Chen & He, 1997) and Baculonistria alba (Chen & He, 1990). The other three belong to the subfamily Necrosciinae of Lonchodidae, including two new species: Micadina conifera Chen & He, 1997, Hemisosibia yintiaolingensis sp. nov. and Dianphasma chongqingensis sp. nov..

Two new combinations of Medaurini (Phasmatodea: Phasmatidae: Clitumninae) from Yunnan Province, China.

Two new combinations are proposed for Chinese species previously described in the endemic Australian genus Pachymorpha Gray, 1835: Interphasma belocerca (Chen & He, 2008) comb. nov., of which the male and egg are described are illustrated for the first time and Neomedaura arguta (Chen & He, 2008) comb. nov., the first report of the genus Neomedaura Ho, 2020, in China.

Nanhuaphasma Chen, He & Li, 2002 is a junior synonym of Dajaca Brunner von Wattenwyl, 1893 (Phasmatodea, Aschiphasmatidae, Dajacini).

The genus Nanhuaphasma Chen, He & Li, 2002 was established as a member of the family Pseudophasmatidae Rehn, 1904 (now belonging to Aschiphasmatidae Brunner von Wattenwyl, 1893) based on the male of N.hamicercum Chen & He, 2002. We review the status of Nanhuaphasma and N.hamicercum by examining the holotype and male and female non-types which were collected in same location as the holotype. We find that Nanhuaphasma is a junior synonym of Dajaca Brunner von Wattenwyl, 1893 and N.hamicercum is a junior synonym of D.napolovi Brock, 2000. Complementing egg morphology of D.napolovi and keys to eight species of Dajaca are provided.

Revision of the Chinese species of Andropromachus Carl, 1913 (Phasmatodea, Lonchodidae, Necrosciinae).

A new species Andropromachus ynau sp. nov.. is described and the Chinese species of the moss-like stick insect genus Andropromachus are reviewed. An updated key to the known species of this genus is provided. Types of the new species are deposited in Yunnan Agricultural University (YNAU).
