Psilotreta trimeresuri , new diagnostic species-group

This diagnostic species-group covers the species having the following combination of genitalic characters: harpagones originate mesally on coxopodites; numerous small spines present on the apex of the harpagones; and presence of parameres in the phallic apparatus. In addition, there are 2 pairs of spines in the phallic apparatus. The species in the group differ from species in the P. japonica diagnostic species-group that is characterized by having 1 pair of parameres. Both pairs of spines originate from the endotheca. Some species has an extremely elongate forewing fork I. In segment X there is no intermediate appendages, except P. spitzeri Malicky from Vietnam, which has the segment X with lateral plates armed with spine likes processes. The 6 known species are recorded from Oriental Region, i.e. between Vietnam and Myanmar: P. angkangensis Malicky & Chantaramongkol, 1993 ( Thailand) , P. quin Malicky & Chantaramongkol, 1991 ( Thailand) , P. malickyi , new species ( Myanmar), P. spitzeri Malicky, 1995 ( Vietnam) , P. trimeresuri ( Malicky, 1989) ( Thailand) , and P. watananikorni Malicky & Chantaramongkol, 1995 ( Thailand) .
