discussion
Remarks. Described in the genus Metrioptera by Uvarov (1924), it was transferred to the genus Roeseliana by Zeuner (1941). Following Tarbinsky (1932) it is synonymous with R. fedtschenkoi, but Zeuner (1941) listed it as valid species. Ramme (1951) considered R. pylnovi and R. fedtschenkoi different taxa, with different shape of wings. Ĝtz (1969) pointed out that the subgenital plate of female is more incised than that of R. fedtschenkoi, but he did not list specimens of the latter species. It seems that R. pylnovi is much related to R. fedtschenkoi and R. roeselii. However, titillators are different from those of R. roeselii (Fig. 6). Instead, the supra-anal plate and cerci of the male are a slightly similar to those of R. roeselii (Fig. 6 d), however, differences may be detected with the female subgenital plate, which in R. roeselii is laterally more rounded (Figs. 8 a and 8 b). See also Tables 2 and 4.
