Diagnosis

Flies of the genus Ectaetia have peculiar wing venation, namely the vein M partly fused with R4+5 (Fig. 5). Ectaetia subclavipes is distinguished from congeners by the structure of the male genitalia (Fig. 6; see also Krivosheina (2002), fig. 28-30).

Distribution

East Russia: Khabarovsk region, Amur province, Tuva, Sakhalin island ( Krivosheina 2002). First record for Europe.

Ecology

Larvae develop under the bark of aspen and poplar ( Krivosheina 2002). According to the authors' data, the species prefers huge wind-broken aspens (diameter 70 cm. and more) fallen 7-10 years ago Table 1. It favoured the trunks colonised by Oxyporus corticola (RS=0.69, P<0.01), Trametes ochracea (RS=0.63, P<0.05) and Hyphoderma setigerum (RS=0.56, P<0.05).
