Andrena (Longandrena) nativa Osytshnjuk 1984

Andrena nativa Osytshnjuk, 1984: 93 ; ♀; Turkmenistan, 100 km NE Kyzyl-Arvat, [Serdar], Kirpili (ZISP) ( Fig. 4 ).

Female (holotype and paratype). Body length (vertex to T6) 7.0–7.5 mm ( Figs 96, 97 ). Head and mesosoma with blue-green metallic sheen, metasoma black. Body mainly with silver-white to gray-white pubescence, in some places with yellow tint due to color of collected pollen. Head: viewed frontally of almost equal width and length (L = 2.1, W = 2.2 mm), very slightly narrowed downwards, almost square, densely longitudinally striated on upper and central part of paraocular areas and on frons, and with inconspicuous hair-bearing punctures ( Fig. 99 ). Lower paraocular area shining, polished, sparsely punctate, punctures small and separated by 2–4 puncture diameters. Facial fovea wide, depressed, especially in lower part, with white pubescence, occupying 2/3 ocellocular distance ( Fig. 102 ), ventrally reaching level of clypeus base. Space between antennal scapes smoother and more densely punctate; supraclypeal area striate-rugose, almost impunctate. Compound eyes weakly convex, slightly wider than in other females of subgenus, 2.4 times longer than their maximum width, inner margin of compound eye curved only in upper half; distance between central and lateral ocelli almost equal to ocellus diameter. Head frontally with more or less long, dense erect hairs, and on genal area with semi-appressed ones. Clypeus slightly elongated, wide, almost hexagonal, centrally broadly concave, polished, strongly shining with very scattered isolated punctures bearing long semi-appressed white hair; lateral margins of clypeus in its basal half and narrow part of its base weakly shagreened, with scattered punctures. Narrow apical margin and widely elongated lateral angles of clypeus strongly depressed, at base of depression and apical half of clypeus laterally with long dense semi- appressed white hairs. Vertex strongly narrowed along posterior margin, widely concave, coarsely shagreened, with sparse punctures, except for smoothed, polished, shiny triangular area located between ocelli; distance between apical margin of vertex and lateral ocellus almost equal to ocellus diameter. Gena upper part moderately broad, equaling width of compound eye, significantly narrowed at lower part; gena surface shagreened, shiny, with sparse hair-bearing punctures ( Fig. 100 ). Malar area short, 5 times wider than its length ( Fig. 104 ). External subantennal sutures clearly discernible ( Fig. 106 ). Mandibles basally black, their apical half light-red with almost undeveloped preapical teeth ( Fig. 105 ); lower margin of mandibles with fringe of long sparse white hair. Process of labrum large, trapezoidal ( Fig. 107 ), 2 times shorter than its width, transversely wrinkled in basal part, smoothed, polished and strongly shining in apical half, depressed margins of process with deep hair-bearing punctures; labrum apically with a cavity that is visible only ventrally ( Fig. 108 ), with dense tuft of short golden-yellow hairs, broadly rounded with slightly elongated lateral corners and with continuous fringe of long thick golden-yellow hairs. Glossa narrow and very long ( Fig. 103 ), more than 15 times longer than its base width, much longer than labial palpus. Galea long, weakly shagreened, with very sparse small superficial punctures bearing thin short setae, and along the lower margin with a fringe of long sparse hair, denser and longer at galea apex ( Fig. 101 ); maxillary palpus slightly longer than galea. Antennae dark above, and flagellum red-yellow beneath ( Fig. 98 ). Mesosoma : W (between tegulae) = 1.6 mm. Pronotum without lateral carinae. Scutum strongly shining, polished, except for weakly shagreened narrow anterior part, with irregularly scattered punctures, separated by 0.5–4 puncture diameters, centrally with very sparse punctures bearing long semi-erect whitish hairs ( Fig. 109 ). Scutellum centrally polished, strongly shiny, almost impunctate, hairless, and on margins clearly shagreened, punctate with dense white erect pubescence. Mesepisternum entirely shagreened with small superficial punctures bearing long, dense plumose hairs. Propodeum finely reticulate, propodeal triangle with shinier and coarser reticulation, well-marked only on posterior half ( Fig. 110 ). Propodeal corbicula incomplete with sparse long weakly flexed hairs; floccus well developed with long more strongly flexed hairs. Tegulae light-yellow, transparent; wings hyaline; venation and stigma yellow; forewing nervulus strongly antefurcal. Tibial scopa with long sparse intermixed simple and weakly plumose silver-white hairs, inner part of tibia with long plumose and weakly flexed hairs; metatibial inner spurs widened almost along entire length, strongly curved at apex ( Fig. 24 ); 2 nd –5 th tarsal segments of all legs widened, yellow-red ( Fig. 28 ); midbasitarsus curved laterally, central inner part of this segment with more short and dark pubescence ( Fig. 111 ). Metasoma: L = 4 mm, W (in widest part) = 2.3 mm, black, ovoid ( Figs 113, 114 ). Terga weakly convex, shining; T1 smoothed, polished, strongly shiny on basal part, weakly shagreened before apical part, with irregularly scattered small punctures, separated by 2–3 puncture diameters, in some parts more sparsely punctate, punctures denser before narrow impunctate apical margin, here separated by one puncture diameter; T2–T4 centrally weakly shagreened, more densely and evenly punctate, punctures separated by 1–2 puncture diameters; T3–T4 weakly and shallowly punctate; apical margins of all terga strongly depressed, lightened, transparent, densely and weakly punctate at base of marginal part. Tergal marginal zones with wide bands of dense and long appressed white hairs narrowly interrupted at T1, apical hairbands on T2–T4 broad, occupying more than 1/3 of tergum length, basal parts of these terga centrally with sparse short semi-appressed white hairs, and with semi-erect hairs laterally. Pygidial plate flat, triangular, rounded at apex, without lateral grooves ( Fig. 112 ). Pygidial and prepygidial fimbriae yellowish-white. Sterna more strongly shagreened and more densely punctate than terga; basal parts of S2–S5 centrally impunctate, hairless, on S3 strongly convex; marginal parts of S2–S5 enlightened, transparent with long appressed thin white hairs ( Fig. 111 ).

Male: unknown.

Studied material: 2 ♀ (holotype and paratype): 1 ♀ Turkmenistan, Kirpili, 100 km NE Kyzyl-Arvat [Serdar] 27.iv.[1]953, [on flowers of] Astragalus , leg. E. Arens (holotype – ZISP; Fig. 4 ) ; 1 ♀ ibid, 27.iv.[1]953, leg. E. Arens (paratype – SIZK; Fig. 7 ).

Distribution. The species is known only by the original description from Turkmenistan (Fig. 2).

Flight period. Late April.

Floral visitation. Females were collected at the flowers of Astragalus (Fabaceae) .
