Diagnosis

The only representative of the genus Clusiodes with no darkening along the costal vein and entirely black scutum (Fig. 12). Male surstylus figured by Mamaev (1974), fig. 1:3 and Lonsdale and Marshall (2007), fig. 41.

Distribution

Known only by the type specimens from East Russia, Primorje region ( Lonsdale and Marshall 2007, Mamaev 1974). First record for Europe.

Ecology

Unknown, but most probably similar to other species of Clusiodes , which develop in dead wood in an advanced state of decay, preferring fallen bark-covered trunks or stumps ( Rotheray and Horsfield 2013). According to the authors' data, this species prefers wind-broken aspens of average diameter (ca. 40 cm) fallen 9 years ago (Table 1). It favoured the trunks colonised by Peniophora incarnata (RS=0.61, P<0.05).
