Karny (1915) described "Ischnoptera sauteri" from Taiwan based on "1♂2♀" taken by H. Sauter. When I examined the type-specimens I found that the material is all female which fact was also noted by Peterson and Gaedike (1970). In his Blattarian catalogue Princis (1969) correctly placed sauteri in the genus Blattella and synonymized Blattella subvittata Hebard (1929) with it. On our material from Taiwan and the other South Asiatic areas I checked the 2 species carefully, and found that the 2 "species" are clearly separated as far as the male supra-anal plate and hypandrium are concerned. The other characters, such as prothoracic pattern, male 7th abdominal tergite, left phallosome and female supra-anal plate seem to be of little value for specific separation. A male specimen from South Thailand affords a rather problematical intermediate feature in the male abdominal end (Fig. 22). I am, therefore, concluding the 2 species to be 2 subspecific taxa of a single species. It is not possible, for the present, to differentiate the 2 subspecies into 2 geographical races.
