Further study on the Oriental stick insect genus Paragongylopus Chen & He, 1997, with additional descriptions and one newly recorded species from China (Phasmatodea; Bacillidae; Gratidiini)

The oriental stick insect Paragongylopus Chen & He, 1997 is a small and poorly known genus, including 9 taxa distributed in China, Thailand and Vietnam. The male and egg of most species in this genus are still unknown. In this paper, two subgenera are re-defined with three new combinations: P. (Planoparagongylopus) brevicornis (Ho, 2019) comb. nov., P. (Planoparagongylopus) obtusidentatus (Ho, 2019) comb. nov., P. (Planoparagongylopus) plaumanni (Zompro, 2000) comb. nov. The male of P. (Paragongylopus) sinensis pingbianensis and the male and egg of P. (Planoaragongylopus) obtusidentatus comb. nov. are described for the first time. Photos of P. (Paragongylopus) sinensis sinensis holotype are given with a remark of its identification with another subspecies. P. (Planoparagongylopus) abramovi is firstly recorded from Yunnan Province of China, and it documents that all species of this genus are distributed in China. A key to identifying two subgenera and a distribution map of this genus from Yunnan and the surrounding area are provided as well.
