Other specimen examined. Adult Ƥ, Xishuangbanna, Yunnan Province, China, I.2009, Chen Chang-Qing (HBU).

Diagnosis. Related to Hainanphasma cristata Ho gen. nov. spec. nov., but this species is separated by occiput lacking high crest and only postero-dorsal carina of metafemora with indistinct lamellae in female; fourth and fifth abdominal terga lacking hump and postero-dorsal carina of meso- and metafemora only with one to two small teeth in male.

Notes. The male was firstly described and illustrated by Zompro (2004: 223). This species was considered to be misidentified in China (Hennemann et al. 2008: 43). The adult specimen ( Fig. 19 ) examined in this study was collected from Yunnan Province that proves the occurrence of this species in China. Measurements are given based on the Chinese material in Table 3.

Distribution. Yunnan (Xishuangbanna), China. Also found in Peninsular Malaysia, Sumatra, Singapore, Cambodia, Thailand and Vietnam.
