Journal of Hymenoptera Research 96: 33-43, DOI: http://dx.doi.org/10.3897/jhr.96.101740, URL: http://dx.doi.org/10.3897/jhr.96.101740
DF9C2E491C385E108B9F21C5916F5DD7.taxon	diagnosis	Diagnosis. According to the male S 7 the new species is apparently closely related to two other very rarely collected and little-known species: Colletes tardus Noskiewicz, 1936, that is only known from southern Ukraine (Proshchalykin and Kuhlmann 2012), and C. ravulus Noskiewicz, 1936, that so far has only been recorded by a few specimens from Siberia (Buryatia Republic, Tyva Republic), NE Mongolia and China (Inner Mongolia, Xinjiang, Shanxi) (Kuhlmann and Proshchalykin 2011; Niu et al. 2014; Proshchalykin and Kuhlmann 2015). As far as known no specimen of C. tardus has survived in museum collections but according to the detailed description of Noskiewicz (1936: 294) the male of C. ravuloides differs from this species by the lack of short appressed hair on the disc of T 1 (Fig. 3 A), shorter hind basitarsus (Fig. 3 B), S 7 longer with posteriolateral corner tapered (Fig. 4 A) (in C. tardus rounded like in C. ravulus (Fig. 4 C )) and gonostylus slightly narrower. Colletes ravuloides and C. ravulus apparently occur in the same region and are very similar in appearance (Fig. 2 A-D). In C. ravulus the punctation of scutum and T 1 is finer and denser (Fig. 3 C), discs of T 3 - 4 without short erect blackish hair, hind basitarsus longer (Fig. 3 D), posteriolateral corner of S 7 rounded and apical emargination deeper (Fig. 4 C), gonostylus slighthly longer and apically rounded (Fig. 4 D). The male of C. ravuloides is best identified by the unique shape of S 7 (Fig. 4 A) in combination with the shortened hind basitarsus (Fig. 3 B).	en	Proshchalykin, Maxim Yu., Kuhlmann, Michael (2023): New and little-known bees of the genus Colletes Latreille, 1802 (Hymenoptera, Colletidae) from Siberia.

DF9C2E491C385E108B9F21C5916F5DD7.taxon	description	Description. Female: unknown. Male. Body length: 9 mm. Head: Head wider than long. Integument black except mandible partly dark reddish-brown. Face densely covered with long, yellowish-white, erect hairs (Fig. 2 A). Malar area medially about 1 / 3 as long as width of mandible base, finely striate. Antenna black, ventrally dark brown. Mesosoma: Integument black. Mesoscutal disc sparsely punctate (i = 3 - 4 d), between punctures smooth and shiny. Scutellum an anterior half nearly impunctate, apically densely punctate (i <1 d), surface smooth and shiny. Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long, yellowish-white to light yellowish-brown erect hair (Fig. 2 A). Wings slightly yellowish-brown; wing venation and stigma brown. Legs with integument mostly blackish, tarsi partly dark yellowish-brown. Vestiture white (Fig. 2 A). Hind basitarsus shortened (Fig. 3 B). Metasoma: Integument black except depressed apical tergal margins posteriorly yellowish-brown translucent (Fig. 3 A). T 1 - 2 densely covered with long, erect yellowish-white hairs (Fig. 3 A), discs of T 3 - 5 with short, erect blackish-brown hair; apical tergal depression and hair bands of T 2 - T 5 broad but narrower medially, about as broad as the respective discs and densely covered with long, appressed white hairs (Fig. 2 B); apical tergal depression and hair band of T 1 only about half the width of the other ones (Fig. 3 A). T 1 finely and densely punctate (i = 0.5 - 1 d), between punctures smooth and shiny (Fig. 3 A), following terga successively with denser punctation. S 7 (Fig. 4 A) and gonostylus (Fig. 4 B) as illustrated.	en	Proshchalykin, Maxim Yu., Kuhlmann, Michael (2023): New and little-known bees of the genus Colletes Latreille, 1802 (Hymenoptera, Colletidae) from Siberia.
