Diagnosis

Gnats of the genus Zygoneura   are distinguished from other Sciaridae   by widely curved fork of wing vein M and long neck of flagellomeres (Fig. 9a). Zygoneura bidens   can be recognised by the two dark spines on a shared lobe in the middle of gonostylus (Fig. 9b; see also Shin et al. (2014), fig. 1: A, B).

Distribution

Palaearctic: Slovakia ( Rudzinski and Ševčík 2012), China, Korea and the Russian Far East ( Shin et al. 2014).

Ecology

Evidently saproxylic as other species of the subgenus Pharetratula   . In Korea, collected at a shiitake farm with oak trunks used as a substrate for shiitake culture ( Shin et al. 2014). According to the authors' data, the species prefers wind-broken aspens with a mean diameter of ca. 40 cm and having died 9 years ago Table 1. It favoured the trunks colonised by Peniophora incarnata   (RS=0.61, P<0.05).
