Scheuchl, Erwin & Hazir, Canan, 2008, Description of a new Andrena species from Turkey, Andrena (Notandrena) selcuki n. sp. (Hymenoptera: Apoidea, Andrenidae), Zootaxa 1763, pp. 63-66 : 63-65

Andrena (Notandrena) selcuki n. sp.

Diagnosis: The body length, pubescence and sculpture of A. selcuki n. sp. are very similar to those of A. chrysosceles ( Kirby, 1802) . The lateral margin of the clypeus is almost straight in A. selcuki ( Fig. 1 a), whereas it is slightly arched in A. chrysosceles ( Fig. 2 a). A. selcuki differs completely in the structure of the genitalia and sternum 8. Its gonocoxites have distinct dorsal lobes and the apical part of the gonostylus is long with a more or less acute apex ( Figs. 1 f, 1g). In contrast, in A. chrysosceles dorsal lobes to the gonocoxites are lacking and the apical part of the gonostylus is short with a rounded apex ( Figs. 2 b, 2c). Sternum 8 of the new species is very broad, its apical width is broader than it is at midlength, and its apical margin is emarginate ( Figs. 1 c, 1d). In A. chrysosceles S8 is more slender, its apical width distinctly narrower than its width at midlength and the apical margin is rounded and slightly acute ( Figs. 2 d, 2e). Further distinguishing characters are: clypeus completely flat, completely shagreened and dull, punctures almost invisible (in A. chrysosceles slightly arched, with a superficially shagreened to smooth and shiny central longitudinal area, punctures conspicuous); distance between lateral ocelli and hind margin of the vertex 1–1.2 ocellar diameters (in A. chrysosceles 1.5 diameters); T2–T3 with uniformly dense punctures (in A. chrysosceles denser laterally than on the disc); veins and stigma brownish, the margin of the latter and costa dark brown (in A. chrysosceles veins and stigma completely yellowish red) lastly, the fimbria of the sterna are shorter in the new species than in A. chrysosceles .

Description: Male: Body length: 8–9 mm (n=2).

Colour: Body black; clypeus whitish yellow, (additional tiny whitish yellow spots at epistomal suture in holotype). Apex of flagellum weakly reddish beneath. Veins and stigma brownish, the margin of the latter and costa dark brown. All tarsi and apex of hind tibiae yellowish red. Spurs of hind tibiae pale yellowish. Apex of gonostyli whitish.

Pubescence: Hairs on head and thorax plumose, rusty yellow, paler on the ventral side. Hairs on legs simple, brownish white. T2–T4 with sparse whitish lateral fringes, caudal fimbria rusty yellowish. S2–S5 with relatively dense and short whitish fimbria.

Structure: Head distinctly (1.33 times) wider than long. Clypeus with very shallow punctures, which are almost invisible because of the shagreening. Malar space not developed. Genal area almost twice as broad as eye, hind margin with a rounded ridge at the dorsal half ( Fig. 1 a). Flagellomere 2 as long as 3 and 4 together; 3 as long as 4 ( Fig. 1 b). Distance of lateral ocelli from hind margin of the vertex 1–1.2 ocellar diameters. – Mesosoma: Pronotum with a pronounced lateral ridge. Mesonotum completely shagreened, dull, with moderately fine punctures separated by 1–2, occasionally up to 3 diameters. Propodeal enclosure with fine granular sculpture; adjacent areas of propodeum very similarly sculptured, but with moderately dense, fine punctures. Submarginal vein 1 about five vein diameters from stigma; discoidal vein meeting submarginal cell 2 at the middle; nervulus antefurcal. – Metasoma: Tergum 1 smooth and shiny, following terga superficially shagreened, more distinct on basal part, with fine punctures separated by 2–3 diameters. Depression of T1 smooth and shiny, without any punctures, depressions on succeeding terga with very superficial shagreening and scattered, extremely fine punctures. Shape of sternum 7 and 8 as in Figs 1 c, 1d, 1e. Gonocoxite of male genitalia with distinct dorsal lobes ( Figs 1 f, 1g).

Female: unknown

Etymology: This new species is dedicated to Selçuk Hazır, to whom the senior author owes so much for his incredible hospitality and generosity, and without whom this species would not have been detected.
