Diagnosis

Andrena tabula sp. nov. can be placed in the subgenus Micrandrena because of its small body size ( Fig. 71 ), black integument, black male clypeus ( Fig. 76 ), and strongly rugose propodeal triangle. It has a strongly flattened clypeus ( Fig. 72 ) and the male genitalia have penis valves that are strongly and conspicuously broadened at the base ( Fig. 78 ), placing it close to A. saxonica Stoeckhert, 1935 and A. garzetta Warncke, 1975 (eastern limit Hatay Province, Turkey).

Female A. tabula sp. nov. can be separated from A. saxonica by the comparatively more flattened clypeus ( Fig. 72 ), flattened over the entirety of its surface (clypeus laterally weakly domed, flattened over ¾ of its surface) and the shinier scutum and scutellum, weakly shining with shagreenation that is comparatively weak (clearly and densely microreticulate, generally dull). In addition to the more flattened clypeus, they can be separated from A. garzetta by the much stronger sculpture and denser punctation of the scutum, punctures separated by 0.5–1 puncture diameter (finely and moderately punctate, punctures separated by 2 puncture diameters, underlying surface finely shagreened, weakly shining).

In addition to the more clearly flattened clypeus, males can most obviously be separated by their genitalia ( Fig. 78 ). Andrena tabula sp. nov. genitalia have the inner margin of the gonostyli raised but straight, more or less parallel with outer margin ( A. saxonica with inner margin of gonostyli raised, curved towards penis valves, and with clear angle apically, not parallel with outer margin) and the gonocoxae are very weakly produced into apical points ( A. garzetta with gonocoxae clearly produced into strong, apically extending points).

Etymology

From the Latin noun ‘ tabula ’, meaning ‘tablet’ or ‘board’, in reference to the extremely flat clypeus in both sexes.

Description

Female

MEASUREMENTS. Body length 7–8 mm ( Fig. 71 ).

HEAD. 1.2 times as wide as long. Clypeus dark, strongly and conspicuously flattened over entire surface, with irregular and variably sized punctures, punctures separated by 1–4 puncture diameters, becoming gradually sparser centrally, central ⅓ of clypeus impunctate ( Fig. 72 ). Clypeus integument with fine granular microreticulation, dull. Process of labrum trapezoidal, slightly wider than long. Face, gena, vertex, and scape with short whitish to brownish hairs. Gena equalling width of compound eyes; ocelloccipital distance slightly less than diameter of lateral ocellus. Foveae extremely narrow, dorsally occupying 1/5 distance between compound eye and lateral ocellus, slightly narrower than width of flagellum, uniform width throughout; foveae filled with whitish hairs. Antennae dark, A(4)5–12 slightly lightened dark reddish-brown below; A3 slightly exceeding A4+5, clearly shorter than A4+5+6.

MESOSOMA. Scutum and scutellum shagreenation, weakly shining, regularly and densely punctate with clear punctures, punctures separated by 0.5–1 puncture diameter ( Fig. 73 ). Pronotum without humeral angle. Mesepisternum, lateral and dorsolateral faces of propodeum with sparse network of raised reticulation, underlying surface dull to weakly shining in places. Propodeal triangle weakly delineated laterally by raised carinae, internal surface strongly and regularly rugose, clearly differing from irregular pattern of reticulation on dorsolateral faces of propodeum. Mesepisternum with moderately long whitish hairs, scutum and scutellum with sparse extremely short brownish hairs, scutellum with occasional scattered long dark brown-black hairs. Propodeal corbiculae thin, dorsally composed of whitish plumose hairs, internal surface with numerous simple white hairs.

Male

MEASUREMENTS. Body length 7–7.5 mm ( Fig. 75 ).

HEAD. 1.3 times as wide as long. Clypeus dark, strongly and conspicuously flattened over entire surface, with irregular punctures, punctures separated by 0.5–3 puncture diameters ( Fig. 76 ). Clypeus integument with fine granular microreticulation, dull. Process of labrum trapezoidal, wider than long, apical margin weakly emarginate.

METASOMA. Terga dark, apical margins of T1 weakly, T2–4 strongly depressed, with extremely narrow hyaline rim. Tergal discs roughened, strongly microreticulate, densely punctate, punctures separated by 1 puncture diameter. Punctures absent from marginal areas, with microreticulation becoming weaker apically, weakly shining; marginal areas strongly contrasting tergal discs. Tergal discs with scattered irregular short white hairs. S8 columnar, apically rounded, ventral surface covered with short brown hairs. Genital capsule large, gonocoxae very weakly produced into apical points. Gonostyli broad, slightly broadening apically with strongly truncate and square-shaped apices, apically flattened and broadly spatulate. Penis valves strongly broadened basally, strongly narrowing apically ( Fig. 78 ).

Remarks

Some of the specimens from Turkey were separated by Warncke with type labels and were called ‘ Andrena galacta Warncke’, but he never published this name. Other Turkish specimens were discovered in undetermined material. For A. saxonica , though the maps of Gusenleitner & Schwarz (2002) show an eastern range limit in the Bosphorus, Turkey, the two taxa can be found in sympatry in eastern Turkey, based on the examination of previously undetermined material.

Distribution

Southern (province of Adiyaman) and Eastern Turkey (province of Hakkâri) and southern Iran (provinces of Ilam, Lorestan, Fars).
