P. bicruris sp. nov., P. paulula sp. nov. and P. jaroschi Malicky, 1995. Another 3 species known from the vicinity of China, i. e. P. quin （Thailand）, P. spitzeri （Vietnam） and P. watauanikorni （Thailand） are also the members of Psilotreta jaroschi group. This newly recognized group is probably monophyletic, as evidenced by 3 characteristics of male species： 1） the second segment of maxillary palp is one half as long as that of the first segment; 2） forewing is absent of DC cell; 3） phallus with 2 pairs of parameres. A key to male species of this species group is provided. All the type specimens are deposited in the Insect Collection of Nanjing Agricultural University, China.
