Type material.

Holotype: 1 ♂, 51.5525°N, 93.9894°E, TYVA, 11 km W of Ust’ -Elegest, steppe, 27.VII.18, Luzyanin, Sidorov" (label in Russian) (ZISP).

Paratype: 1 ♂, same data as Holotype (RCMK).

Diagnosis.

According to the male S7 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 T1 (Fig. 3A View Figure 3 ), shorter hind basitarsus (Fig. 3B View Figure 3 ), S7 longer with posteriolateral corner tapered (Fig. 4A View Figure 4 ) (in C. tardus rounded like in C. ravulus (Fig. 4C View Figure 4 )) and gonostylus slightly narrower. Colletes ravuloides and C. ravulus apparently occur in the same region and are very similar in appearance (Fig. 2A-D View Figure 2 ). In C. ravulus the punctation of scutum and T1 is finer and denser (Fig. 3C View Figure 3 ), discs of T3-4 without short erect blackish hair, hind basitarsus longer (Fig. 3D View Figure 3 ), posteriolateral corner of S7 rounded and apical emargination deeper (Fig. 4C View Figure 4 ), gonostylus slighthly longer and apically rounded (Fig. 4D View Figure 4 ). The male of C. ravuloides is best identified by the unique shape of S7 (Fig. 4A View Figure 4 ) in combination with the shortened hind basitarsus (Fig. 3B View Figure 3 ).

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. 2A View Figure 2 ). 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 = 3-4d), between punctures smooth and shiny. Scutellum an anterior half nearly impunctate, apically densely punctate (i <1d), surface smooth and shiny. Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long, yellowish-white to light yellowish-brown erect hair (Fig. 2A View Figure 2 ). Wings slightly yellowish-brown; wing venation and stigma brown. Legs with integument mostly blackish, tarsi partly dark yellowish-brown. Vestiture white (Fig. 2A View Figure 2 ). Hind basitarsus shortened (Fig. 3B View Figure 3 ).

Metasoma: Integument black except depressed apical tergal margins posteriorly yellowish-brown translucent (Fig. 3A View Figure 3 ). T1-2 densely covered with long, erect yellowish-white hairs (Fig. 3A View Figure 3 ), discs of T3-5 with short, erect blackish-brown hair; apical tergal depression and hair bands of T2 - T5 broad but narrower medially, about as broad as the respective discs and densely covered with long, appressed white hairs (Fig. 2B View Figure 2 ); apical tergal depression and hair band of T1 only about half the width of the other ones (Fig. 3A View Figure 3 ). T1 finely and densely punctate (i = 0.5-1d), between punctures smooth and shiny (Fig. 3A View Figure 3 ), following terga successively with denser punctation. S7 (Fig. 4A View Figure 4 ) and gonostylus (Fig. 4B View Figure 4 ) as illustrated.

Etymology.

The species name refers to its similarity to the closely related C. ravulus that occurs in the same region.

Distribution.

The only record is from the type locality in Tyva Republic (Russia).
