D i a g n o s i s: Colletes alborzensis   belongs to the Colletes fodiens   species-group and is most closely related to C. inexpectatus   NOSKIEWICZ. The female of the new species is very similar to C. inexpectatus   and only differs by a combination of the following subtle characters: Eyes slightly more converging below and clypeus more convex with apical grooves a bit larger ( Figs 1, 4 View Figs 1-6 ), punctation on the disc of T1 slightly finer ( Figs 2, 5 View Figs 1-6 ). The male is identifiable by the characteristic shape of S7 ( Figs 8, 11 View Figs 7-11 ), denser punctation of metasomal terga ( Figs 7, 10 View Figs 7-11 ) and slightly longer but narrower hind basitarsi ( Figs 3, 6 View Figs 1-6 ).

D e s c r i p t i o n

F e m a l e: Body length: 8.0– 8.5 mm. Head distinctly wider than long ( Fig. 1 View Figs 1-6 ). Integument black, mandible apically dark reddish-brown. Face sparsely covered with moderately long greyish, erect hair, on vertex hair shorter ( Fig. 1 View Figs 1-6 ). Clypeus strongly convex, with a shallow longitudinal median depression, supraclypeal area almost rectangular, large and slightly convex in profile. Clypeus finely, regularly and densely punctate (i <0.5d); surface between punctures smooth and shiny, inconspicuous pair of apical clypeal depressions ( Fig. 1 View Figs 1-6 ). Malar area medially narrow, about 1/2 as long as width of mandible base, finely punctate and partly shiny. Antenna black. Scutum on disc impunctate and shiny, laterally finely and densely punctate (i <0.5d), between punctures smooth and shiny. Scutellum anteriomedially impunctate, smooth and shiny; rest of scutellum densely and coarsely punctate (i <0.5d). Thorax sparsely covered with long greyish hair. Wings fuscous, venation blackish-brown. Legs black, vestiture whitish, scopa white. Integument of metasoma black, apical tergal depressions narrowly translucent dark yellowish-brown ( Fig. 2 View Figs 1-6 ). Terga on disc with few short, erect, greyish hairs, apical depressions apical hair bands ( Fig. 2 View Figs 1-6 ). T1 apically only very slightly depressed, depression superficially and finely punctuate, apical margin impunctate ( Fig. 2 View Figs 1-6 ). T1 on disc moderately dense (i = 0.5–1.0d) and relatively finely punctate, between punctures smooth and shiny ( Fig. 2 View Figs 1-6 ). No apical sternal hair bands but instead some long, erect ciliae.

M a l e: Body length: 8.0– 8.5 mm. Head distinctly wider than long. Integument black except tips of mandible partly dark reddish-brown. Face densely covered with long, yellowish-white, erect hairs. Malar area medially about half as long as width of mandible base, finely striate. Antenna black. Mesosoma. Integument black. Mesoscutal disc coarsely and sparsely punctate (i = 1–2d), smooth and shiny. Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long yellowish-white, erect hairs. Wings transparent; wing venation blackish-brown. Legs. Integument black. Hind basitarsus apically broadened ( Fig. 3 View Figs 1-6 ). Vestiture whitish to greyish-brown. Metasoma. Integument black except narrow apical margins of terga reddish translucent. Discs of T1 – T2 covered with long, erect whitish hairs that are apically successively shorter ( Fig. 7 View Figs 7-11 ); apical tergal hair bands broad, white. Terga densely and finely punctate (i <d), between punctures smooth and shiny ( Fig. 7 View Figs 7-11 ). Terminalia. Genitalia and S7 as illustrated ( Figs 8–9 View Figs 7-11 ).

E t y m o l o g y: The species is named after the Alborz Mountains in northern Iran where specimens of the new species were collected.

G e n e r a l d i s t r i b u t i o n: Only known from the type locality in northeastern Iran.

F l o r a l h o s t s: Unknown.
