Beardius triangulatus Andersen et Saether View in CoL

Beardius triangulatus Andersen et Saether, 1996: 43 View in CoL .

Material examined. Type material, as in Andersen & Saether (1996).

Diagnostic characters. The species belongs in the triangulatus group. The male can be separated from all other members of the genus by the combination of the following characters: median volsella wart-like; inferior volsella with basal, triangular projection with comparatively long macrotrichia; and AR about 0.5.

Description. The male was described in detail by Andersen & Saether (1996); the structure considered to be the “median volsella” is here regarded as a basal, triangular projection of the inferior volsella. The wart-like tubercle at the base of this projection must be regarded as the median volsella.

Distribution. The species is recorded from Costa Rica ( Andersen & Saether 1996).
