Psilotreta japonica , new diagnostic species-group

This diagnostic species-group includes species characterized by the following characters: harpagones originating from the apex of the coxopodites; numerous small spines on the apex of the harpagones; and presence of phallic parameres, represented by a single pair besides the variously formed sclerotized phallotremal sclerites inside the endotheca. An exception is observed in P. abudeb Malicky & Chantaramongkol , having a pair of phallic parameres in the holotype, and 2 pairs of phallic parameres in a single specimen from Myanmar, a specimen also having large spines on each harpago. Regarding the phallic parameres in the latter individual, the pair located basally in the endotheca may represent the parameres being homolog with parameres in related species, while the apical pair is associated with the phallotremal sclerite complex. Some species, like P. lobopennis Hwang from China, has complex gonocoxites, with ventrad and dorsad producing lobes on the coxopodites, but with apically originating harpagones. This diagnostic species-group is the most species rich group in the genus and includes the following 31 species in the (eastern) Palaearctic and Oriental Regions: P. abudeb Malicky & Chantaramongkol, 1991 ( Myanmar) , P. aello Malicky & Chantaramongkol, 1996 ( Thailand) , P. aidoneus Malicky, 1997 ( Nepal) , P. albogera Mey, 1997 ( Vietnam) , P. androconiata Mey, 1997 ( Vietnam) , P. assamensis Parker & Wiggins, 1987 ( India) , P. baurea Malicky, 1989 ( Thailand) , P. bidens Mey, 1995 ( Vietnam) , P. chinensis Banks, 1940 ( China: Sichuan), P. daidalos Malicky, 2000 ( China: Hennan), P. daphnis Malicky, 2000 ( China: Zhejiang), P. daktylos Malicky, 2000 ( China: Hennan), P. dardanos Malicky, 2000 ( China: Zhejiang), P. enikoae , new species ( Vietnam) P. falcula Botosaneanu, 1970 ( Korea) , P. frigidaria Mey, 1997 ( Vietnam) , P. illuan Malicky, 1989 ( Thailand) , P. japonica Banks, 1906 ( Japan) , P. jaroschi Malicky, 1995 ( Vietnam) , P. kisoensis Iwata, 1928 ( Japan) , P. kwantungemsis Ulmer, 1925 ( China: Guangdong), P. lobopennis Hwang, 1957 ( China: Fujian), P. locumtenens Botosaneanu, 1970 ( Korea) , P. ochina Mosely, 1942 ( China: Fujian), P. orientalis Hwang, 1957 ( China: Fujian), P. papaceki Malicky, 1995 ( Vietnam) , P. pyonga Oláh, 1985 ( Korea) , P. quadrata Schmid, 1959 ( China: Yunnan), P. quinglingshanensis Mey & Yang, 2001 ( China: Sichuan), P. quinlani Kimmins, 1964 ( Nepal) , P. schmidi Parker & Wiggins, 1987 ( India) , and P. trispinosa Schmid, 1965 ( China: Zhejiang).
