Diagnosis. The species has elongate-trapezoid postgonites, relatively narrow V-shaped divergent hypandrial processes, both phallic hooks present, connecting ventrally (forming closed ring, right hook slightly shorter than left hook), median extension of postgonites saw-toothed ventrally ( Figs 1 – 2 ). Presutural area mostly similarly coloured as rest of mesoscutum in males but lighter in females.

Distribution. Mountains of Central and Southern Europe.

Remarks. Bicellaria albopilosa was described from numerous specimens originating from the Krkonoše Mts, Orlické hory, and Carpathian Mts ( Slovak Republic and Romania), exclusively from high altitudes (from 800 to 2200 m) (Chvála 1991). Chvála (ibid.) illustrated the fore and hind legs, antenna and hypandrium.

There may be at least one similar species (see Bicellaria sp. 5 in section “Unidentified specimens”) and, therefore, careful examination of genitalia is necessary.
