Filchneria

DIAGNOSIS: A single species of the genus is known from Mongolia. The genus is characterized by the absence of external genitalia and by the presence of raised spinule patches on abdominal tergites 8–10 ( Fig. 274). The tength tergum of the male is not deeply cleft and without accessory hemitergal processes, characteristics shared with Diura . The female subgenital plate is distinctly heart shaped with a deep posterior notch separating two rounded lobes ( Fig. 275). Nymphs ( Fig. 276) are distinguished by a unique lacinial structure with closely spaced teeth and fewer, shorter hairs on the inner edge. In contrast, other Perlodinae have more separated apical teeth and dense, long hairs along the inner edge.
