Psychristus (Psychristus) dentatus JAEGER, 2009

Material examined: China Yunnan: Xishuangbanna, 20 km NW Jinghong, vic. Man Dian (NNNR), N22°07.80 E100°40.05, 730 m, BF, forest, 6.VI 2009, L. Meng (1♂ - cJAE).

The original description of the species was based on two females only. The specimen from Yunnan, which represents the first male of the species, agrees in general appearance well with the female types. The pro- and mesotarsomeres 1-4 are moderately dilated with biseriately arranged adhesive hairs beneath. The median lobe of the aedoeagus ( Figs 8-9 ) is, compared with other species of the P. discretus group, markedly larger, and the internal structures comprises three groups/fields of large teeth, instead of fields of very small and fine teeth in other species.

P. dentatus species was hitherto known from North Thailand (Mae Hong Son) and North East India (Meghalaya state) (JAEGER 2009: 1637) It is here recorded for China (Yunnan) for the first time.
