Figs 66–69

Material examined

PORTUGAL • 1 ♂; Algarve , Tareja; [37.173° N, 7.879° W]; 13 Apr. 1991; J. v. Corstanje leg.; NMNL (illustrated Figs 66–69 ) .

Description

Male

MEASUREMENTS. Body length 9 mm ( Fig. 66 ).

HEAD. Black, 1.1 times as wide as long ( Fig. 67 ). Clypeus black, slightly domed and slightly flattened centrally, densely punctured laterally with punctures separated by 0.5 puncture diameters, becoming sparser centrally, separated by 1 puncture diameter, narrow central impunctate line present. Gena, clypeus, and inter-antennal area with white hairs, vertex with a mixture of white, brown, and black hairs, and frons and inner margin with black hairs, all hairs variable in length, longest exceeding length of scape. Antennae uniformly dark, A3 slightly shorter than A4+5.

MESOSOMA. Scutum shagreened, very weakly shining, densely punctured, punctures separated by 0.5–1 puncture diameter, slightly sparser centrally. Scutellum comparatively less shagreened, weakly shining, very densely punctured, punctures separated by <0.5 puncture diameters. Episternum and propodeum reticulate, dull. Propodeal triangle large, clearly marked with raised carina, internal surface with weak longitudinal rugae. All parts of mesosoma with long white hairs which exceed length of scape. Legs dark, apical tarsal segments lightened orange, including hind basitarsi. Wings hyaline, venation orange, nervulus interstitial.

METASOMA. Terga dark, apical margins lightened dark red, very densely and uniformly punctate, punctures separated by 0.5 puncture diameters, underlying surface weakly shagreened, shining ( Fig. 68 ). T1–4 with loose apical hair bands, those on T1–3 interrupted, on T4 complete. S8 short, projecting area as wide as long, apical margin notched. Genitalia long, gonocoxa inflated, therefore forming a channel along their internal margins, apical teeth broadly rounded ( Fig. 69 ). Penis valve triangular, narrowing apically to a rounded point. Gonostyli narrow and elongate, dorsal face flattened and bearing sparse, short hairs.

Remarks

Andrena baetica is morphologically close to A. mocsaryi Schmiedeknecht, 1883 , but differs in the shorter, squamous hairs on the scutum ( Wood et al. 2020). The discovery of this male material further confirms the proximity of A. baetica to A. mocsaryi through genital structure ( Fig. 69 , see illustrations in Schmid-Egger & Scheuchl 1997), but also confirms its specific status as it possesses an entirely black clypeus, whereas A. mocsaryi has a yellow clypeus, and the apex of S8 is truncate to slightly emarginate, whereas in A. mocsaryi it is slightly pointed ( Schmid-Egger & Scheuchl 1997).

Distribution

Southern Spain (Cadiz, Los Alcornocales; Cazorla, Sierra Pozo) and southern Portugal (Alentejo; Algarve) ( Wood et al. 2020).
