Notes.

Warncke (1975b) described Andrena allosa pileata from the Chelmos mountains in Greece. The type series of A. allosa pileata is mixed and includes two distinct species. The first species, represented by the holotype, is briefly redescribed here. No specimen was available for genetic study. This first species appears clearly distinct from A. allosa and A. amieti sp. n., and we treat it as a valid species, A. pileata Warncke stat. n.

Description.

Female: Body length 9mm. Clypeus shorter than in A. allosa , as in A. bicolor , without flattened apical area, regularly convex, densely punctate, interspaces weakly shagreened even apically (Suppl. material 3: Fig. S10). Malar space as in A. bicolor , shorter than in A. allosa . Fovea as in A. bicolor or A. allosa , markedly narrower inferiorly than superiorly. Mesonotum nearly entirely matt, silk-shiny only medially, comparatively densely punctate, except medially (there interspaces up to 3-4 puncture diameters). Terga entirely shagreened, finely, regularly punctate even medially on discs, interspaces 3 puncture diameters (Suppl. material 3: Fig. S12). Apical tergal margins weakly impressed apically, more so than in A. allosa . The sculpture of the terga is similar to that of A. ruficrus and unlike A. amieti sp. n. or A. allosa . Vestiture predominantly brown (both specimens are not fresh), medially on face grey-brown, laterally dark; vestiture on mesonotum orange-brown, made of comparatively short, strongly plumose hairs, with only few, very short dark hairs (Suppl. material 3: Fig. S11). Hairs on lateral and ventral sides of mesosoma grey-brown. Scopa brown-orange. Hairs on metasoma comparatively short, metasomal terga without loose apical fringes of white hairs, at most with isolated, short hairs (Suppl. material 3: Fig. S12).

Male: unknown; the male paratype is likely not conspecific and probably belong to Andrena sp1.

Examined material.

Holotype female of A. pileata ; one additional female from the Chelmos mountains, Greece (Suppl. material 1).
