Andrena (Micrandrena) dividicincta Pisanty sp. nov.

( Figs. 102–109 )

Female ( Fig. 102 ).

Body length: 7–7.5 mm.

Colour. Body dark brown ( Fig. 102 ). Flagellum entirely dark brown. Femora, tibiae and basitarsi dark brown; apical tarsal segments reddish-brown. Wings slightly infuscate, veins brown, stigma orangish-brown ( Fig. 102 ). Tergal marginal zones light to dark brown ( Fig. 105 ).

Pubescence. Head and mesosoma covered with whitish to light brown plumose hairs of moderate length and density ( Figs. 102–104 ). Facial fovea with dense, minute brownish hairs ( Fig. 104 ). Propodeal corbicula incomplete, posterodorsal fringe with long plumose hairs. Surface of corbicula with few long simple hairs. Leg hair whitish-golden ( Fig. 102 ). Flocculus incomplete. Scopal hairs mostly simple, unilaterally plumose on posterior part. Surface of tergal discs almost bare medially, with very sparse, short bright hairs laterally. Tergal marginal zones 2-4 with distinct interrupted bands of very dense white hairs, covering 1/2–2/3 of tergal width. Terminal fringe golden ( Fig. 105 ).

Head ( Figs. 103–104 ). 1.1 times broader than long. Galea shiny, superficially shagreened. Labral process broad and short, more or less arched. Clypeus very weakly convex, almost flat, shagreened basally, shagreened to smooth apically, distance between punctures 1–1.5 puncture diameters, puncture size medium, without impunctate midline ( Fig. 103 ). Paraocular area strongly punctate below, strongly longitudinally grooved above. Supraclypeal area weakly punctate to longitudinally grooved. Flagellomere 1 about as long as 2+3, 2 as long as 3 or slightly shorter. Frons strongly longitudinally striated, with an areolate midline. Facial fovea narrow, almost linear, extending from level of medial ocellus to base of clypeus, 0.4 times as broad as antennocular distance, distinctly separated from compound eye ( Figs. 103–104 ). Distance of fovea from lateral ocellus about 2 ocellus diameters. Ocelloccipital distance 1 ocellus diameter. Vertex carinate ( Fig. 104 ).

Mesosoma ( Fig. 104 ). Dorsolateral angle of pronotum not to very weakly elevated, pronotum not carinate laterally. Mesonotum entirely matt and strongly shagreened, coarsely but very shallowly, obliquely punctured, punctures visible mostly in anterior view, distance between punctures 1–2 puncture diameters. Scutellum similar, slightly shinier ( Fig. 104 ). Mesepisternum matt, finely alveolate, impunctate, anterior part weakly rugose-areolate. Propodeal triangle finely rugose-areolate mediobasally, alveolate apicolaterally ( Fig. 104 ). Posterolateral part of propodeum finely alveolate, impunctate, sculpturing finer compared to triangle. Propodeal corbicula shiny, finely reticulated, impunctate. Hind leg pretarsal claws distinctly bidentate. Submarginal crossvein 1 reaching marginal cell 1–2 vein widths from stigma. Recurrent vein 1 reaching marginal cell 2 at its middle or proximal to it. Nervulus interstitial to very weakly antefurcal.

Metasoma ( Fig. 105 ). Tergal discs moderately to weakly shagreened, somewhat shiny, impunctate, shagreenation strongest on tergum 2 and weakest on 3–4. Tergal marginal zones weakly depressed, basal part more weakly shagreened than disc, apical part smooth.

Male ( Fig. 106 ).

Body length. 6 mm.

Colour. Similar to female. Clypeus and paraocular areas dark ( Fig. 107 ).

Pubescence. Head and mesosoma with long, plumose, mostly yellowish hair ( Figs. 106–107 ). Frons, lateral part of paraocular area, and upper part of genal area with short to medium dark hairs ( Figs. 106–107 ). Metasomal hair similar to female, but terminal fringe whitish ( Fig. 108 ).

Head ( Fig. 107 ). 1.2 times broader than long. Clypeus almost flat, very smooth and shiny, strongly and densely punctate, distance between punctures 0.5–2 puncture diameters, puncture density increasing laterally, without impunctate midline. Flagellomere 1 slightly shorter than 3, 2 slightly shorter than 1 ( Fig. 107 ). Rest of head similar to female.

Mesosoma. Similar to female.

Metasoma ( Fig. 108 ). Tergal disc 1 shiny, very superficially shagreened, weakly, sparsely and very finely punctate, distance between punctures 2 puncture diameters. Tergal discs 2–5 shagreened basally and smooth apically, shagreenation decreasing gradually towards distal terga, punctation weak, sparse and very fine, distance between punctures 2–3 puncture diameters. Tergal marginal zones weakly depressed, smooth to very slightly shagreened, impunctate.

Genitalia and hidden sterna ( Fig. 109 ). Gonocoxites separated almost from base, dorsal gonocoxite lobe strongly developed, rounded. Gonostylus blade strongly and abruptly broadened apically. Penis valves broad basally, strongly tapering apically ( Fig. 109 ). Sternum 8 simple, columnar, narrow, apical process spatulate, not broadened.

Diagnosis. Andrena dividicincta is closely related to A. querquedula Warncke from Turkey, and both species are easily distinguished from most Micrandrena by the almost flat clypeus, impunctate female terga, broad and finely granular propodeal triangle, and unique pattern of metasomal hair bands. Andrena dividicincta differs from A. querquedula in the stronger shagreenation of the male clypeus (smooth in A. querquedula ) and female and male terga (completely smooth in female A. querquedula , and to a lesser extent in the male).

Distribution: Northern Israel (Upper Galilee and Mount Hermon). Likely present also in Lebanon and Syria.

Flight period: February–April.

Flower records: Rosaceae : Prunus dulcis , Pyrus syriaca ; Sapindaceae : Acer monspessulanum .

Pollen analysis. Six analysed pollen loads from Mount Hermon, Montfort and Meron Junction contained 31.2% Sapindaceae (Acer) , 30.6% Rosacaeae ( Prunus - type, Crataegus - type), 19.0% Rhamnaceae ( Rhamnus - type), and 19.0% an unidentified, featureless pollen type ( Poaceae ?). The species therefore appears to be polylectic, favouring flowering trees and shrubs.

Etymology. dividicincta = Latin for “with divided belt”, in reference to the species’ strongly interrupted tergal hair bands. The species epithet is an adjective.
