Epischnomyia merzi Roháček, 2009

( Figs 51, 52 )

Material examined. NORTH KOREA (D.P.R.Korea):Paekdusan Mts, Onsupjong, 19.viii.1989, 1♀, M. Kozánek leg. ( SMOC, genit. prep.).

Remarks. This species is very similar and closely related to E. triarmigera (for detail see RඈIJගඹൾκ 2009).

Biology. Information obtained from a recent record from Sichuan (RඈIJගඹൾκ 2018) indicates that this, and probably also other species of Epischnomyia , are associated with dicotyledonous plants in herbaceous undergrowth of humid leafy forests. Adults were encountered in May (RඈIJගඹൾκ 2018), June (RඈIJගඹൾκ 2009) and August (the present record).

Distribution. The species was described from South Korea (RඈIJගඹൾκ 2009) and later recorded from China (Sichuan). The first record from North Korea (see above) represents a new northernmost occurrence of the species.
