Andrena (Chlorandrena) danini Pisanty & Scheuchl

n. sp.

Andrena (Chlorandrena) danini Pisanty & Scheuchl   n. sp.

( Fig. 3 View FIGURE 3 )

Female ( Fig. 3 View FIGURE 3 A). Body length: 8–9 mm.

Color. Head and mesosoma black ( Fig. 3 View FIGURE 3 A –C). Posterior side of flagellomeres black; anterior side of flagellomeres 1–3 black, 4 partly reddish, 5–10 reddish-orange. Legs dark brown to black. Wings transparent, veins and stigma golden. Tergal discs black; marginal zones brownish-yellow ( Fig. 3 View FIGURE 3 E). Sternal discs brown to black; marginal zones brownish-yellow.

Pubescence. Hairs mostly whitish-golden and plumose. Face with long golden hairs ( Fig. 3 View FIGURE 3 B). Facial foveae with brown hairs above, whitish hairs below. Genal area with golden hairs, much longer ventrally. Mesonotum, scutellum and metanotum with sparse, very short bright hairs covering entire surface, and long whitish-golden hairs along lateral margins ( Fig. 3 View FIGURE 3 C). Mesepisternum with long whitish-golden hairs. Propodeal corbicula incomplete, posterodorsal margin with long golden hairs; surface of corbicula with very short hairs. Legs with white to golden hairs; flocculus white; scopa golden. Tergal discs with short, thin bright hairs covering entire surface and long whitish-golden hairs laterally ( Fig. 3 View FIGURE 3 E –F). Marginal zones of terga 2–4 with bands of dense whitish hairs, discontinuous on tergum 2, continuous on terga 3–4. Prepygidial fimbria golden ( Fig. 3 View FIGURE 3 F). Marginal zones of sterna with long whitish-golden hairs.

Head ( Fig. 3 View FIGURE 3 B –C). Broader than long ( Fig. 3 View FIGURE 3 B). Glossa 6 times as long as broad. Labral process rectangular to trapezoidal, apex concave. Clypeus weakly convex, strongly punctured, basal part shagreened, apical part smooth to superficially shagreened, distance between punctures 1 puncture diameter. Flagellomere 1 twice as long as broad, slightly shorter than 2+3+4; 2–4 shorter than broad, 2–3 more or less equal in length; 5 almost square. Facial fovea broad, broadest and deepest above, shallower and slightly narrower below, occupying 1/3–1/2 of paraocular area, extending from level of middle of lateral ocellus to slightly below antennal sockets ( Fig. 3 View FIGURE 3 C). Distance of fovea from lateral ocellus and ocelloccipital distance about 1 ocellus diameter ( Fig. 3 View FIGURE 3 C).

Mesosoma ( Fig. 3 View FIGURE 3 C –D). Dorsolateral angle of pronotum not elevated. Mesonotum coarsely punctured, distance between punctures 0.5–2 puncture diameters; anterior 1/4–1/2 of mesonotum shagreened, posterior part smooth ( Fig. 3 View FIGURE 3 C). Scutellum smooth, more finely punctured than mesonotum, distance between punctures 0.5–2 puncture diameters ( Fig. 3 View FIGURE 3 C). Mesepisternum reticulately shagreened, shiny, coarsely but shallowly punctured, distance between punctures 0–1 puncture diameters. Surface of propodeal corbicula reticulately shagreened, shiny, its center impunctate. Propodeal triangle rugose basally, reticulately shagreened and shiny apically ( Fig. 3 View FIGURE 3 D). Posterolateral part of propodeum roughened, shiny, reticulated ( Fig. 3 View FIGURE 3 D). Inner side of hind femur with row of ca. 11–14 small peg-shaped projections. Hind leg pretarsal claws with distinct inner tooth. Recurrent vein 1 meeting marginal cell 2 at about 2/3 of distance between submarginal crossveins 1–2. Nervulus interstitial to antefurcal.

Metasoma ( Fig. 3 View FIGURE 3 E –F). Terga with medium-sized, regular, not crater-like punctures (i.e. puncture margins not raised). Disc of tergum 1 superficially shagreened to smooth, distance between punctures 1–3 puncture diameters ( Fig. 3 View FIGURE 3 F). Discs of terga 2–4 shiny, shagreened to smooth, distance between punctures 1–2 puncture diameters ( Fig. 3 View FIGURE 3 E). Marginal zones of terga 1–4 shagreened, very finely and shallowly punctured, those of terga 2–4 occupying about 1/2 tergum width ( Fig. 3 View FIGURE 3 E). Pygidial plate almost flat, central part alveolate.

Male. Unknown.

Differential diagnosis. This species resembles A. exquisita Warncke   and A. tadauchii Gusenleitner   , but differs from them by its smaller body size, slightly longer flagellomere 1 (in A. exquisita   and A. tadauchii   only slightly longer than 2+3), different sculpturing of dorsal part of propodeum (posterolateral parts of propodeum and apex of triangle almost smooth in A. exquisita   , strongly reticulate-alveolate in A. tadauchii   ), and different punctation of tergum 1 (finer and sparser in A. exquisita   , with distinct crater-like punctures in A. tadauchii   ). A. danini   differs further from A. exquisita   by the narrower and straighter facial foveae, orange flagellomeres 4–10 (brown in A. exquisita   ), denser punctation of mesonotum, and interstitial to antefurcal nervulus (postfurcal in A. exquisita   ). The tergal marginal zones of A. danini   are broader than those of A. tadauchii   .

Flight period: February –April. One specimen was apparently collected in July (note in pencil), but this could be an error.

Flower records: none. The species likely forages on Asteraceae   as do many other related Chlorandrena spp. ( Westrich 1989).

Etymology. The species is named in honor of Avinoam Danin, a prominent Israeli botanist (1939–2015).
