Diagnosis

Male epiproct is oval dorsally, slightly widening in the anterior half, becoming narrow basolaterally. Paired lateral arms of the dorsal sclerite directed obliquely down towards the middle, nearly touching and sclerotized; the paired dorsal folds deep and covered with comb-like scales. Each apical sclerite of the epiproct is elongated and flat-lying, with the base extending beyond the dorsal folds, directed obliquely downward, slightly widened at the apex and the edge of the distal apex is rounded and rough, bearing fine comb-like scales and 3–4 stout lateral spines. Female sternum 7 extended medially, forming a well-developed, broadly rounded and swollen pregenital plate, which is slightly (?) sclerotized, overlapping sternum 8 completely and the anterior margin of sternum 9 partly (Fig. 4 A-E).

Distribution

Russia, Far East ( Teslenko and Boumans 2018). The species is recorded for China for the first time.
