Abstract
The endemic southeastern Asiatic Pristaulacus comptipennis species group is revised and illustrated. Twenty species are recognized: P. asiaticus Turrisi & Smith, sp. nov. (China), P. boninensis Konishi (Japan), P. comptipennis Enderlein (Japan, China, Taiwan, Laos), P. corellianus Turrisi & Smith, sp. nov. (Laos), P. dilleri Turrisi & Smith, sp. nov. (Laos), P. emarginaticeps Turner (Vietnam), P. excisus Turner (Vietnam), P. gusenleitneri Turrisi & Smith, sp. nov. (Thailand), P. insularis Konishi (Japan, South Korea), P. jenningsi Turrisi & Smith, sp. nov. (Laos), P. konishii Turrisi & Smith, sp. nov. (Thailand), P. lagrecai Turrisi & Smith, sp. nov. (Vietnam), P. nobilei Turrisi & Smith, sp. nov. (China), P. porcatus Sun & Sheng (China), P. sharkeyi Turrisi & Smith, sp. nov. (Thailand), P. thailandensis Turrisi & Smith, sp. nov. (Thailand), P. vietnamensis Turrisi & Smith, sp. nov. (Vietnam, Thailand), P. vilhelmseni Turrisi & Smith, sp. nov. (Laos), P. vivaldianus Turrisi & Smith, sp. nov. (Laos), P. watanabei Turrisi & Smith, sp. nov. (Thailand). Phylogenetic analyses are based on a previous set of 79 morphological characters. Of this data set, 28 informative including five newly added characters were analysed using TNT under different schemes (equal and implied weighting). All analyses support two large clades, the first with five species, and a more derived and diverse one containing 15 species. Other minor clades are identified and discussed. A key for identification of the species is provided.
