Andrena (Truncandrena) bassana Warncke: Gusenleitner & Schwarz 2002: 116–117.

Description of female (Fig. 96).

Body length: 11.5–12.5 mm.

Colour. Body dark. Anterior side of flagellomeres 4–10 reddish. Tergal marginal zones reddish to black, becoming yellowish near apex (Fig. 90). Wings slightly infuscate, veins and stigma brown (Figs. 96, 99).

Pubescence. Head and mesosoma mostly with minutely plumose golden hair (Figs. 89, 94–98). Lower 2/3 of face with moderately long golden hair, with highest density on the outer margin of antennal sockets (Fig. 94). Facial foveae with dense minute yellowish hair (Fig. 89). Vertex and genal area with golden hair (Figs. 89, 94, 96). Mesonotum, scutellum and metanotum with thick golden hairs, very short, sparse and inconspicuous centrally, dense and moderately long peripherally (Figs. 89, 96). Mesepisternum with long, dense golden hair, becoming slightly whitish ventrally. Propodeal corbicula incomplete, dorsal margin with fringe of long, moderately plumose golden hairs, upper half of corbicular surface with extremely dense, short yellowish plumose hair, with a texture reminiscent of a carpet (Fig. 98). Leg hair whitish to golden (Figs. 95–96). Tibial scopa composed of simple golden hairs. Flocculus complete, whitish (Fig. 95). Surface of tergal disc 1 with sparse, medium-lengthed yellowish hairs, the following discs with minute, inconspicuous bright hairs. Apices of tergal marginal zones 2–4 with narrow, complete bands of moderately dense whitish hair. Terminal fringe golden (Figs. 90, 96).

Head (Figs. 89, 94, 96). 1.15 times broader than long (Fig. 94). Mandible bidentate. Galea very finely shagreened. Glossa 2.7 times longer than broad. Labral process triangular, apex thickened, minutely bidentate. Clypeus almost completely flat, surface weakly shagreened on basal ¼, elsewhere smooth, punctation coarse, dense and strong, distance between punctures 0.5–1 puncture diameters, without impunctate midline (Fig. 94). Lower part of paraocular area smooth, finely and densely punctured. Malar area undeveloped, eye margin almost touching mandible base. Supraclypeal area moderately protuberant, longitudinally striated, finely and densely punctured. Facial foveae broad throughout, almost rectangular, very shallow above, deeper below, extending from level of upper margin of lateral ocellus to base of clypeus, 0.65 times as wide as antennocular distance, separated from compound eye by smooth linear area (Figs. 89, 94). Distance of fovea from lateral ocellus about 1.1 ocellar diameters. Flagellomere 1 0.85 times shorter than 2+3+4 (Fig. 94). Frons strongly longitudinally striated, interspersed with fine punctures. Ocellar triangle very densely, finely punctured. Ocelloccipital distance 1.9 ocellar diameters (Fig. 89). Genal area about 1.1 times wider than compound eye. Preoccipital ridge weakly carinate dorsally, rounded laterally.

Mesosoma (Figs.89,95,97–99).Dorsolateral angle of pronotum distinctly elevated, forming a strong dorsolateral carina. Mesonotum weakly shagreened to almost smooth anteriorly, smooth centrally, densely punctured, distance between punctures 0.5–1 puncture diameters on anterior margin, 1–4 puncture diameters on disc. Scutellum smooth, densely punctured, distance between punctures 0.5–2 puncture diameters (Fig. 89). Surface of mesepisternum with strong, very fine alveolation, overlayed by weak punctures separated by 0.5–1 puncture diameters. Surface of lower half of propodeal corbicula strongly shagreened (Fig. 98). Basal part of propodeum moderately sloping, apical part longer, more or less vertical. Surface of posterolateral part of propodeum with very strong, fine alveolation, overlayed by coarse and dense, ill-defined punctures. Propodeal triangle narrow, almost T-shaped, surface mat, lateral and apical margins very finely, shallowly alveolated, central area with weak, ill-defined fine rugae (Figs. 89, 97). Inner side of hind femur rounded. Inner hind tibial spur more or less straight and of uniform width. Hind pretarsal claw with strong inner tooth. First recurrent vein meets submarginal cell 2 beyond its middle. Submarginal crossvein 1 enters marginal cell 4–6 vein widths from stigma. Nervulus slightly postfurcal (Fig. 99).

Metasoma (Fig. 90). Tergal discs mostly smooth and shiny, strongly and densely punctured, distance between punctures 1–2 puncture diameters on tergum 1, 0.5–1 puncture diameters on terga 2–4. Tergal marginal zones very broad and arched, weakly to moderately depressed, surface sculpture similar to tergal discs except for basal margins which are more sparsely punctured. Pygidial plate normally developed, without elevated medial area.

Distribution: Gaza Strip *, Israel, West Bank, Jordan *, Syria *.

Flight period: February–April. A single male was apparently collected in July.

Flower records: Asteraceae: Pallenis spinosa; Brassicaceae: Sinapis sp.; Ranunculaceae: Ranunculus asiaticus .

Pollen preferences: Four analysed loads from Bet Guvrin, Lakhish and Ya’arot Hakarmel contained 40% Boraginaceae ( Echium - type), 38% Papaveraceae ( Papaver), 20% Asteraceae ( Anthemis - type, Crepis - type), and 2% Brassicaceae ( Sinapis - type). The species therefore appears to be polylectic.

Remarks. Due to the dearth of available material and the differing morphologies of the two sexes, in his original account of A. bassana, Warncke (1969) could not confidently associate the females with the males, and therefore described only the latter. Six years later, having examined more material from Turkey and the Levant, he very briefly described the female of A. b. etesiaca (herein elevated to species status), in terms of the distinguishing characters from the nominate subspecies, which was still left undescribed (Warncke 1975). This is unfortunate, as the holotype of A. b. etesiaca is a female. An adequate description of the females of either subspecies was therefore essentially lacking, and the above treatment is given to amend this issue.
