Pseudopelmatops Shiraki

Pseudopelmatops Shiraki, 1933: 49 . Type-species: P. nigricostalis Shiraki, 1933, by original designation.

Pseudopelmatops was proposed by Shiraki (1933) for a single species, P. nigricostalis from Taiwan, China. Zia & Chen (1954) added two species from Zhejiang, China, P. angustifasciatus and P. continentalis . Chen et al (2010) revised this genus, added two more species, P. indiaensis Chen from India and P. yunnanensis Chen from China, and provided a key. In subsequent years, some new information on its distribution and biology has accumulated. The northernmost distribution of the genus is now known to extend to Shaanxi and Henan Provinces in central China which is regarded as the Oriental-Palearctic transition zone. Detailed environmental conditions at the collection sites of P. angustifasciatus and P. continentalis are also reported here and analyzed, and observations of the behaviour of these species in the field are recorded for the first time. In addition, P. angustifasciatus is first recorded from Vietnam, and the male is associated with the female by mating behaviour and described for the first time. Moreover, we provide supplemental morphological information for P. angustifasciatus, P. continentalis, P. indiaensis and P. yunnanensis .
