Andrena (Holandrena) fimbriatoides Scheuchl 2004

( Fig. 6 )

Female ( Fig. 6 A). Body length: 10.5–11 mm.

Color. Head, mesosoma and terga black; sterna brown. Anterior side of flagellomeres 4–10 brownish-black. Femora, tibiae and basitarsi black to dark brown; distal part of tarsi brown. Forewings transparent, slightly brownish; hindwings transparent; wing veins brown.

Pubescence. Clypeus almost bare ( Fig. 6 B). Paraocular, supraclypeal and genal areas with white hair ( Fig. 6 B). Foveae and vertex with golden hair ( Fig. 6 C). Anterior side of mesonotum with whitish-golden hair. Mesepisternum with white hair. Propodeal corbicula incomplete, posterodorsal margin with white hair; surface of corbicula with sparse white hair. Legs with white to golden hair, the latter especially on tarsi. Flocculus white, strongly plumose. Scopa with white, usually simple hairs; few hairs on outer side of tibia unilaterally plumose. Terga with very short and thin inconspicuous hairs; marginal zones of 2–4 with narrow white hair bands ( Fig. 6 D). Prepygidial fimbria golden ( Fig. 6 D). Premarginal lines of sterna with long, white to golden hairs.

Head ( Fig. 6 B–C). Broader than long, sometimes weakly so ( Fig. 6 B). Galea finely shagreened. Labral process very broad, trapezoidal. Clypeus more or less flat medially, fully shagreened and uniformly punctured, without impunctate midline; distance between punctures 1–2 puncture diameters, puncture side medium to large ( Fig. 6 B). Facial foveae very shallow above, tapering and deepening downwards, occupying 1/3–1/2 of paraocular area, extending from level of medial ocellus to lower end of antennal socket ( Fig. 6 B–C). Distance of fovea from lateral ocellus 1.5–2 ocellus diameters ( Fig. 6 C). Flagellomere 1 2.5 times as long as broad, slightly shorter than 2+3+4; 2–3 broader than long ( Fig. 6 B); 4–5 almost square. Ocelloccipital distance 1–1.5 ocellus diameters ( Fig. 6 C).

Mesosoma ( Fig. 6 C). Dorsolateral angle of pronotum elevated, with strong carina extending down laterally. Mesepisternum very coarsely and densely punctured, distance between punctures 0–0.5 puncture diameters. Mesonotum shiny, superficially shagreened, smooth on top; puncture size large to medium, distance between punctures 1–3 puncture diameters. Scutellum similar, smooth. Propodeal triangle and corbicula strongly rugoseareolate, corbicula more coarsely so. Posterolateral part of propodeum smooth and shiny, strongly and densely punctured, distance between punctures 0–0.5 puncture diameters, puncture size medium-large. Hind leg pretarsal claws bidentate. Nervulus postfurcal.

Metasoma ( Fig. 6 D). Terga 1–3 smooth and shiny; 4 smooth to superficially shagreened; 5 shagreened. Terga 1–4 densely and very strongly punctured, distance between punctures 0.5–1 puncture diameters, slightly sparser on tergum 1; puncture size large to medium, decreasing from tergum 1 to 4. Marginal zones of terga 2–4 weakly depressed. Tergum 5 very shallowly punctured, distance between punctures 1–2 puncture diameters, puncture size medium to small. Pygidial plate flat, central part shagreened and not elevated.

Differential diagnosis. The female of A. fimbriatoides is easily distinguished from other members of the subgenus Holandrena by the fully shagreened clypeus (smooth to superficially shagreened in A. decipiens Schenck , A. forsterella Osytshnjuk , A. labialis (Kirby) , A. variabilis Smith and A. wilhelmi Schuberth ) and the smooth and shiny, coarsely punctured tergum 1 (shagreened and matt in A. fimbriata Brullé ; more finely punctured in A. decipiens , A. forsterella , A. labialis , A. labiatula Osytshnjuk , A. variabilis and A. wilhelmi ).

Flight period: March–April.
