Scathophaga inquinata (MEIGEN, 1826) ( Figs 17–20 )

M a t e r i a l e x a m i n e d: CZECH REPUBLIC: Praha, Milíčovský rybník, pond (6053)

10.v.1999, 1♂, 1♀, Šifner leg. (FSPC). D i a g n o s i s. Male. The submedial processes very short, lateral part of sternite 5

long haired latero-caudally, sternites 4 to 2 distinctly rectangular and covered with short bristles ( Fig. 17 ), distyli long and pointed, cerci in upper part long haired ( Fig. 18 ), pregonite with three apical bristles ( Fig. 19 ).

Female. The abdominal sternite 7 distictly narrowed caudally, in apical part covered with long fine bristles ( Fig. 20 ).

C o m m e n t s. The original description of S. inquinata is based similarly as in S. analis on the colour characters. However, all available data show that it is a valid species. The basic diagnostic characters are on the terminalia: the short submedial processes of sternite 5 short ( Fig. 17 ) and pregonite with three apical bristles ( Fig. 18 ) in male; the abdominal sternite 7 distinctly narrowed caudally ( Fig. 20 ) in female.

D i s t r i b u t i o n. All of Central European countries except Switzerland ( ŠIFNER 2018).
