Colletes edentuloides Kuhlmann

Kuhlmann, Michael & Yu, Maxim, 2011, Bees of the genus Colletes Latreille 1802 of the Asian part of Russia, with keys to species (Hymenoptera: Apoidea: Colletidae), Zootaxa 3068, pp. 1-48 : 24

Colletes edentuloides Kuhlmann sp. n.

( Figs 27 a–b)

This species is not known from Russia but is described here because the discovery of the true female of C. ravulus (see above) finally confirmed it is a new species. All specimens assigned to C. ravulus in Kuhlmann (2010) belong to the new species C. edentuloides . The female of this species is very similar to those of C. edentulus and C. tuberculatus Morawitz , which have been described by Kuhlmann (2010) and Noskiewicz (1936) respectively.

Female.

Diagnosis.

Colletes edentuloides differs from C. edentulus and C. tuberculatus in its smaller clypeal apical grooves ( Figs 27 a, 27c, 27e). Furthermore, C. edentuloides and C. tuberculatus differ in the sculpture of the clypeus and in the punctation of the terga. In C. edentuloides , the distance between the punctures of the clypeus is slightly greater ( Fig. 27 a) than in C. tuberculatus ( Fig. 27 e), but the sculpture is otherwise identical. In C. edentuloides , the punctation on the disc of T1 is much denser and the punctures are slightly smaller ( Fig. 27 b) than in C. tuberculatus ( Fig. 27 f). In both species the punctation becomes much smaller and denser apically, but more so in C. edentuloides ( Fig. 27 b). In C. edentulus ( Fig. 27 d) the punctation on the disc of T1 is much more dispersed than in C. edentuloides ( Fig. 27 b) while the sculpture of the clypeus is almost identical with the punctation of the disc slightly smaller and more dense in the former ( Fig. 27 c) than in C. edentuloides ( Fig. 27 a).

Description

Bl = 9.0–10.0 mm. Head. L = 2.0–2.2 mm; W = 3.1–3.5 mm. Head wider than long. Integument black except tips of mandible partly dark reddish-brown. Face except clypeus densely covered with long, whitish-grey, erect hairs. Clypeus with a shallow longitudinal median depression, supraclypeal area convex in profile. Clypeus finely and densely punctate; surface between punctures shiny ( Fig. 27 a). Supraclypeal area with a few, relatively small punctures; surface strongly shagreened and dull. Malar area medially about ¼ as long as width of mandible base, finely striate. Antenna black. Mesosoma. Integument black. Mesoscutal disc between punctures smooth and shiny; disc sparsely punctate (i = 2.0–4.0d). Scutellum anteriorly sparsely punctate with more dense punctation apically, surface smooth and shiny. Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with yellowish-white erect hairs. Wings. Slightly yellowish-brown; wing venation brown. Legs. Integument black. Vestiture whitish, scopa white. Metasoma. Integument black except narrow apical margins of T brownish translucent; T 1 in some specimens with a slight oily-bluish shine. T1 anteriorly sparsely covered with short to long, partly appressed white hairs ( Fig. 27 b); discs of T2 to T6 without white hairs; apical tergal hair bands broad. Terga densely and finely punctate (i <d) ( Fig. 27 b).

Male. Unknown.

Type material (17 specimens). Holotype, female, Mongolia, 50 km N Ulaanbaatar, riv. E of Mandal [106°46'E 48°22'N], 1180m, 8–13.VIII.2007, M. Halada leg. ( OÖLM).

Paratypes: 11 Ƥ, same dates as holotype ( OÖLM, RCMK); 5 Ƥ, same dates as holotype but collected by J. Halada ( RCMK).

Etymology. This species is named C. edentuloides to stress its similarity with C. edentulus that occurs in the same region of Mongolia.

General distribution. Only known from the type locality.

Floral hosts. Unknown.

Seasonal activity (first–last observations). VII–VIII.
