Material examined.

Morocco: Guelmim-Oued Noun, 15-16.iv.1995, 3♂, 1♀, leg. Ma. Halada, OÖLM; Souss-Massa, 10 km S Taroudant, 12.iv.1995, 1♀, leg. Ma. Halada, allotype male and one other male deposited in the OÖLM, with one male and one female retained in the personal collection of TJW.

Distribution and remarks.

Known only from south-western Morocco ( Warncke 1980). Gusenleitner and Schwarz (2002) provided comments on the appearance of the male but this was not a formal description and so one is provided here. Andrena guichardi can be easily recognised within the Poliandrena by the extremely shiny and very sparsely punctate scutum (Fig. 115 ).

Description.

Male: Body length 9 mm (Fig. 113 ). Head: Black, clearly wider than long. Clypeus slightly arched, predominantly yellow but with two dark triangular marks intruding laterally (Fig. 114 ). Underlying surface smooth and shiny, densely punctured, punctures separated by one puncture diameter except centrally where there is a small impunctate circular area. Process of labrum narrow, weakly emarginate, shiny. Gena slightly wider than the width of a compound eye. Gena, face, vertex, and scape with long white hairs, equalling length of the scape. Antennae dark, A3 apically and A4-12 completely lightened orange below, A3 exceeding A4, shorter than A4+5. Ocelloccipital distance broad, two times wides than width of lateral ocellus. Surface of galea shagreened, dull. Mesosoma: Scutum and scutellum sparsely punctate, punctures separated by 2-4 puncture diameters, underlying surface very smooth and shiny (Fig. 115 ). Episternum weakly reticulate, underlying surface weakly shining. Propodeum microreticulate, dull, propodeal triangle marked by small but clearly defined slightly raised carina, internal structure weakly and finely rugose. Scutum, scutellum, episternum, and propodeum with long white hairs, these often exceeding the length of the scape. Legs dark, tarsi lightened brown, pubescence white. Wings hyaline, venation and stigma brown, nervulus antefurcal. Metasoma: Tergites dark brownish, margins lightened whitish, apically translucent (Fig. 116 ). Tergal discs very weakly reticulate, shining, tergites densely and finely punctured, punctures separated by one puncture diameter. T1-5 with loose white hair bands, on T1 interrupted, T2-5 complete. T6-7 centrally with golden fringe of hairs. S2-5 with apical fringes of white hair.

Other material examined.

Morocco: Sidi-Ifni, within 100 m of the sea, 31.iii.1974, 1♀, leg. K.M. Guichard & G.R. Else, OÖLM (paratype).
