Genus Neopseudatrichia, new genus

 except for the male and female terminalia. The male ninth tergum 

 short, not concealing the tenth segment, no comb of sternal hairs 

 as in Pseudatrichia, aedeagus consists of a short median penis flanked 

 by two short parameres, eighth sternum of female prolonged on the

 to the Australian region.
