Diagnosis

Andrena sani sp. nov. can be placed in the subgenus Euandrena in the female sex because of the characteristically drop-shaped foveae which are narrowed below, and the simple scopal hairs. It is most similar to A. alijevi and to A. oblata sp. nov. because of the centrally flattened clypeus and thick yellow tergal hairbands ( Fig. 35 View Figs 31–36 ). Andrena sani can be separated from A. alijevi because of the uniformly light brown hairs on the vertex, paraocular area, and scutum ( Figs 31–32 View Figs 31–36 ) (hairs here greyish-brown with admixture of black hairs) and the slightly impressed longitudinal impunctate line on the clypeus surrounded by dense punctures ( Fig. 33 View Figs 31–36 ) (clypeus without impressed longitudinal line, centrally with scattered punctation). Andrena sani can be separated from A. oblata by the slightly impressed longitudinal impunctate line on the clypeus surrounded by dense punctures (clypeus without impressed longitudinal line, centrally with scattered punctation) and the weaker tergal puncturing, punctures here sparse and obscure ( Fig. 36 View Figs 31–36 ), separated by 2–4 puncture diameters (punctures dense, distinct, separated by 1–2 puncture diameters; compare Figs 30 View Figs 25–30 and 36 View Figs 31–36 ).

Males are harder to diagnose (as for most Euandrena ), but the combination of the characters A3=A4, dark, non-metallic terga, predominantly black facial pubescence, non-elongated clypeus, scutum finely granulate and matt, terga finely shagreened with sparse indistinct punctures ( Fig. 39 View Figs 37–40 ), and simple genital capsule ( Fig. 40 View Figs 37–40 ) places it close to A. alijevi . It can be separated because of the slightly impressed impunctate longitudinal line on the clypeus, the clypeus otherwise entirely densely punctate (clypeus without longitudinal impunctate line, apical ⅓ smooth and shiny with scattered punctures) and the facial pubescence, which is extensively white centrally, black laterally (predominantly black, with occasional pale hairs).

Description

Female

MEASUREMENTS. Body length 9.5–10.5 mm ( Fig. 31 View Figs 31–36 ).

HEAD. 1.2 times as wide as long ( Fig. 32 View Figs 31–36 ). Clypeus dark, flattened over majority of its area, densely punctate, punctures separated by 0.5–1 puncture diameter with exception of clear impunctate longitudinal line centrally with width of 2 puncture diameters; longitudinal line slightly impressed, giving impression of weak furrow ( Fig. 33 View Figs 31–36 ). Clypeus basally and laterally shagreened, weakly shining, becoming smooth and shiny apically. Process of labrum rounded-trapezoidal, twice as broad as long, apical margin very weakly emarginate. Face, gena, scape, and vertex with long pale brown hairs, longest equalling length of scape; face laterally and frons with some intermixed black hairs. Gena slightly exceeding width of compound eye; ocelloccipital distance equalling diameter of lateral ocellus. Fovea narrow dorsally, occupying just under ½ distance between lateral ocellus and compound eye, slightly narrowed below at level of antennal insertions; filled with dark brown hairs. Antennae dark, A3 exceeds A4+5, shorter than A4+5+6.

MESOSOMA. Scutum and scutellum shagreened, shagreenation slightly irregular, scutum duller laterally, weakly shining centrally; surface punctate, punctures separated by 1–2 puncture diameters ( Fig. 34 View Figs 31–36 ). Pronotum without humeral angle. Mesepisternum and lateral faces of propodeum with fine granular reticulation, weakly shining. Propodeal triangle narrow, weakly delineated laterally with fine carinae, internal surface with fine granular reticulation, dull, basally with slightly raised rugae. Dorsolateral faces of propodeum with weakly shining fine granular reticulation and fine raised rugosity, propodeal triangle therefore distinguished by absence of rugosity. Mesosoma with long light brownish hairs, becoming whitish ventrally, longest on mesepisternum, equalling length of scape; propodeal corbicula with plumose hairs comprising dorsal fringe, internal surface with sparse plumose hairs. Legs uniformly dark, pubescence dark to light brownish; tibial scopae light brownish, femoral scopae and flocculus whitish. Hind tarsal claws with inner tooth. Wings hyaline, stigma dark orange centrally with dark brown margin, venation dark brown to dark orange; nervulus interstitial to slightly antefurcal, first recurrent vein enters second submarginal cell at its midpoint.

METASOMA. Terga dark, marginal areas of T2–4 depressed, T1–4 with apical margins widely lightened yellow-hyaline ( Fig. 35 View Figs 31–36 ). Terga strongly shagreened, weakly shining, with faint and obscure fine punctures, punctures separated by 2–4 puncture diameters, marginal areas basally punctate ( Fig. 36 View Figs 31–36 ). T1–4 on discs with sparse long golden hairs, on T1 extending onto margin to form comparatively weak apical band, not obscuring underlying surface, T2–4 with dense complete hairband of long whitish hairs that obscures underlying surface. Apical fringe of T5 whitish laterally, becoming dark brown centrally, hairs flanking pygidial plate dark brown; pygidial plate rounded triangular, with faint raised rounded longitudinal ridge centrally.

Male

MEASUREMENTS. Body length 8–8.5 mm ( Fig. 37 View Figs 37–40 ).

HEAD. 1.2 times as wide as long. Clypeus dark, flattened over majority of its area, densely and uniformly punctate, punctures separated by 0.5 puncture diameter with exception of slightly impressed longitudinal impunctate line, width equal to 1 puncture diameter ( Fig. 38 View Figs 37–40 ). Clypeus surface weakly shining throughout. Process of labrum rounded-trapezoidal, apical margin broadly and weakly emarginate. Face centrally with extensive long white hairs from antennal insertions to apex of clypeus, replaced laterally by entirely black hairs that extend onto frons; longest hairs exceeding length of scape. Gena and vertex with predominantly whitish hairs, with occasional intermixed black hairs. Gena slightly elongate, exceeding width of compound eye; ocelloccipital distance equals diameter of lateral ocellus. Antennae dark, A3=A4.

MESOSOMA. Scutum and scutellum with fine granular shagreen, weakly shining, irregularly punctate with large shallow punctures, punctures separated by 1–3 puncture diameters. Structurally otherwise as in female. Mesosoma with long whitish-light brownish hairs, only propodeum with scattered individual black hairs intermixed. Legs dark, pubescence whitish with black hairs restricted to fore femorae apically. Hind tarsal claws with inner tooth. Wings as in female.

METASOMA. Terga dark, T1–4 with apical margins slightly depressed, apically lightened yellow-hyaline ( Fig. 39 View Figs 37–40 ). Tergal discs finely shagreened, weakly shining, shagreenation absent from marginal areas, these contrasting, more brightly shining. Tergal discs with obscure faint fine punctures, punctures separated by 2–4 puncture diameters. Disc of T1 with long whitish hairs, T2–5 with shorter whitish hairs, T2–4 with thick white apical hairbands that obscure underlying surface laterally, becoming weaker medially. S8 apically broadened, apex truncate, ventral surface covered with short brown hairs. Genital capsule simple, gonocoxa with very slightly produced rounded apical teeth, gonostyli apically spatulate, flattened, slightly broadened. Penis valves narrow, essentially parallel-sided ( Fig. 40 View Figs 37–40 ).
