description: Andrena (Poecilandrena) stenofovea Scheuchl & Pisanty n. sp.
(Figs. 8, 21, 32, 36, 49, 58, 81, 94, 107, 120, 132, 138)
Female. Body length: 6–6.5 mm.
Color. Mandibles black basally, reddish apically. Face, mesonotum, scutellum and metanotum black with weak to strong bronze metallic luster (Figs. 8, 36). Flagellomere 1 black, 2–10 black to reddish-orange, the latter especially on anterior side of 4–10. Mesepisternum and propodeum black (Fig. 49). Legs brown to black. Wings hyaline, veins brown, stigma orange. Tergal discs dark brown to black (Fig. 58). Tergal marginal zones brown to black.
Pubescence. Hair on head and anterior part of thorax mostly brightly colored and minutely plumose. Clypeus, supraclypeal, paraocular and genal areas, and frons with whitish hairs of medium length and density. Vertex with long whitish hairs. Mesonotum, scutellum and metanotum with sparse, brownish to whitish, medium to long hairs. Mesepisternum with dense, long white hairs. Propodeal corbicula incomplete, posterodorsal margin with long, white plumose hairs. Surface of corbicula with few long, simple white hairs. Flocculus developed, with long, white plumose hairs. Femora with white hairs. Tibiae with white to brownish hairs. Tarsi with light to dark brown hairs. Scopa small, with white unilaterally plumose hairs. Tergal discs with minute inconspicuous hairs medially, and sparse, whitish medium hairs laterally. Tergal marginal zones 2–4 with narrow white hair bands, discontinuous on 2, almost continuous on 3, continuous on 4. Prepygidial fimbria beige-golden.
Head. About as long as broad. Galea finely shagreened. Labral process small, triangular, smooth (Fig. 8). Clypeus weakly convex, basal 2/3 shagreened, apical 1/3 smooth, shallowly and sparsely punctured, with a broad impunctate midline, distance between punctures 1.5–3 puncture diameters, puncture size medium (Fig. 8). Facial foveae linear and extremely narrow, about as wide as 1/5 antennocular distance above, narrowing to a fissure of negligible width below, extending from level of middle of lateral ocellus to below base of antennal socket, separated from the compound eye by a distinct smooth area of up to 1/5 antennocular distance (Fig. 21). Flagellomere 1 twice as long as broad, slightly longer than 2+3; 2 broader than long, 3 almost square, 4–5 square. Distance of fovea from lateral ocellus 1.5–2 ocellus diameters. Ocelloccipital distance 3/4–1 ocellus diameter.
Mesosoma. Dorsolateral angle of pronotum not to minutely elevated, pronotum not carinate. Mesonotum shagreened, shallowly and sparsely punctured, distance between punctures 1–3 puncture diameters and often more on medial part, puncture size medium (Fig. 36). Scutellum similar, but punctation extremely shallow and almost unrecognizable (Fig. 36). Mesepisternum shagreened, anteriodorsal part densely but shallowly punctured, distance between punctures 1 puncture diameter. Basal part of propodeum more or less horizontal and relatively broad. Propodeal triangle finely reticulate, medial part finely and shallowly rugose (Fig. 49). Propodeal corbicula shagreened and impunctate, except for hair bases that resemble punctures. Inner side of hind femur rounded, not carinate. Hind tibial spurs more or less straight and of uniform width. Hind leg pretarsal claws with small inner tooth. Recurrent vein 1 meeting submarginal cell 2 at its middle or closer to submarginal crossvein 1; nervulus distinctly antefurcal (Fig. 32).
Metasoma. Tergal discs shagreened, shagreening of 2–4 often much shallower apically; punctation very fine and shallow, recognizable mostly on the smoother apical parts, distance between punctures 1–3 puncture diameters (Fig. 58). Tergal marginal zones shagreened, narrow, occupying 1/5–1/3 tergum width, not to moderately depressed, often hardly discernible from discs. Pygidial plate alveolate, not elevated medially.
Male. Body length: 5.5–6 mm.
Color. Similar to female, but clypeus yellow medially (Fig. 81).
Pubescence. Head and thorax mostly with long, minutely plumose hairs. Clypeus with dense long white hairs. Paraocular area with long dark hairs. Genal area with long dark hairs dorsally and very long white hairs ventrally. Supraclypeal area, scape and vertex with both white and dark, medium to long hairs. Mesonotum, scutellum, metanotum, mesepisternum and propodeum with long white to brownish hairs. Femora and tibiae with white hairs. Tarsi with white to light brown hairs. Tergal discs with minute inconspicuous hairs medially, and sparse, whitish medium hairs laterally. Tergal marginal zones 2–4 with narrow white hair bands, discontinuous on 2, almost continuous on 3, continuous on 4; marginal zone 5 with broad band of very sparse white to yellowish hairs. Prepygidial fimbria white to yellowish.
Head. 1.1–1.2 times broader than long. Galea finely shagreened. Clypeus weakly convex, shagreened to smooth basally and smooth apically, moderately punctured, distance between punctures 1–2 puncture diameters; an impunctate midline is sometimes weakly indicated (Fig. 81). Flagellomere 1 as long as 2+3, 1.5–2 times as long as broad; 2 broader than long, the following longer than broad. Ocelloccipital distance 1–1.25 ocellus diameters.
Mesosoma. Similar to female.
Metasoma. Tergal discs shagreened basally, shagreened to smooth apically, finely but distinctly punctured, distance between punctures about 2 puncture diameters (Fig. 107). Tergal marginal zones occupying 1/4–1/3 of tergal width, shagreened to smooth, finely, sparsely, and weakly to strongly punctured, shagreenation weakest and punctation strongest on terga 2–3.
Genitalia and hidden sterna. Gonocoxites connected. Dorsal lobe of gonocoxite distinct, rounded apically (Fig. 120). Blades of gonostyli shovel-shaped, flattened, rounded apically (Figs. 120, 132). Penis valves narrow, tapering apically (Figs. 120, 132). Sternite 8 columnar, densely and uniformly hairy, strongly broadened apically (Fig. 138).
Differential diagnosis. A. stenofovea is easily distinguishable from all other species of Andrena (Poecilandrena). The female is immediately recognized by the extremely narrow facial foveae and the small, triangular labral process. The male is distinguished by the combination of a shagreened, weakly and sparsely punctured cuticle, yellow clypeus, dark paraocular area covered with dark hair, dark metasoma, and simple-shaped genital capsule (dorsal gonocoxite lobes rounded, penis valves not broadened, gonostyli not elongate).
Distribution: Israel.
Flight period: January–April.
Flower records: Brassicaceae: Sinapis alba (1♂); Brassicaceae sp. (1♀).
Etymology. The species is named after the very narrow facial foveae characteristic of the female.
