D i a g n o s i s: Colletes sirjanensis is best characterized and identified by the shape of S7 and the gonostylus ( Figs 17, 18 ). In C. arztbergi S7 is distinctly longer than broad and apically truncate (about as broad as long and apically emarginate in C. sirjanensis ) and tarsi are orange-brown (blackish in C. sirjanensis ). Colletes fuscicornis has a S7 that is about 1.5 times longer and broader, gonostylus is distinctly longer, narrower and parallelsided. In C. schwarzi S7 is almost round while S 7 in C. nanaeformis has a shape very similar to that of C. sirjanensis but is 1/3 smaller and the gonostylus is longer and narrower.

D e s c r i p t i o n

M a l e: Body length: 6–8 mm. Head: Head wider than long. Integument black except mandible partly dark reddish-brown. Face densely covered with long, white, erect hairs. Malar area medially about 2/3 as long as width of mandible base, finely striate. Antenna black, ventrally yellowish-brown ( Fig. 13 ). Mesosoma: Integument black. Mesoscutal disc almost impunctate, smooth and shiny. Scutellum in the anterior half nearly impunctate with a few scattered punctures apically, surface smooth and shiny. Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long, greyish to white erect hairs ( Figs 13, 14 ). Wings slightly yellowish-brown; wing venation and stigma yellowish-brown, apically dark brown. Integument of legs mostly black to dark brown, tarsi partly reddish to yellowish-brown. Vestiture white. Metasoma: Integument black except depressed apical tergal margins whitish to yellowish translucent. Anterior half of disc of T1 sparsely covered with short, appressed hairs and disc entirely with few long, erect white hairs ( Figs 15, 16 ); apical tergal depression and hair bands of T2 – T5 about as broad the respective discs and densely covered with short, appressed white hairs; apical tergal depression and hair band of T1 narrower, T2 with broad basal hair band ( Figs 15, 16 ). Terga very finely and densely punctate (i <0.5d), between punctures smooth and shiny ( Fig. 16 ). T7 apically broadly rounded. Gonostylus and S7 as illustrated ( Figs 17, 18 ).

F e m a l e: Unknown.

E t y m o l o g y: The species is named after the city of Sirjan. In the vicinity of Sirjan most of the specimens were collected.

G e n e r a l d i s t r i b u t i o n: The species is so far only known from the provinces Kerman and Bushehr in the south of Iran ( Fig. 20 ).

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