Colletes packeri Kuhlmann , sp. nov.

( Figs 8 View FIGURE 8 a–d; 9a, c; 10a, c)

Diagnosis. In both male and female of C. packeri the metasomal terga are extremely finely and densely punctate and the apical tergal hair bands are very narrow ( Fig. 9 View FIGURE 9 c, 10a). Within the C. clypearis group these characters are only shared with C. sodalis ( Cameron) ( Fig. 9 View FIGURE 9 d, 10b) making them unmistakable. Thus, the diagnosis is here restricted to the differences between them. In the female the punctation of terga is more dispersed in C. packeri and apical tergal hair bands are narrower ( Fig. 9 View FIGURE 9 c) than in C. sodalis ( Fig. 9 View FIGURE 9 d). The punctation of the clypeus is slightly denser in C. sodalis ( Fig. 9 View FIGURE 9 b) than in C. packeri ( Fig. 9 View FIGURE 9 a). In the males, differences in punctation and pilosity of metasomal terga match those of the females ( Figs 10 View FIGURE 10 a, b). In C. packeri S7 is yellowish-brown, shorter and narrower ( Fig. 10 View FIGURE 10 c) than in C. sodalis that is dark brown ( Fig. 10 View FIGURE 10 d).

Description. Female. Bl = 7.0–9.0 mm. Head wider than long. Integument black, mandible partly dark reddish-brown. Face, except clypeus, sparsely covered with long, yellowish-white, erect hairs, on vertex and along inner eye margin brown to blackish ( Fig. 9 View FIGURE 9 a). Clypeus convex, with shallow longitudinal median depression, supraclypeal area rectangular and convex in profile. Clypeus coarsely and densely punctate (i <0.5d), particularly in the median depression, subapically slightly coarser punctate; surface between punctures smooth and shiny, small pair of apical clypeal depressions ( Fig. 9 View FIGURE 9 a). Malar area medially narrow, about 1/4 as long as width of mandible base, finely striate and matt. Antenna black, flagellum ventrally dark brown. Mesosoma. Integument black. Mesoscutal disc sparsely punctate (i = 2–3d), smooth and shiny between punctures. Mesoscutellum anteriomedially impunctate, smooth and shiny; apically densely punctate ( Fig. 8 View FIGURE 8 c). Mesoscutum, mesepisternum and propodeum densely covered with long bright orange-brown, erect hairs, on mesoscutum and mesoscutellum intermixed with abundant blackish hairs ( Figs 8 View FIGURE 8 a, c). Wings. Slightly yellowish; wing venation dark brown. Legs. Integument black. Vestiture whitish to blackish, scopa ventrally dark grey to blackish, dorsally black. Metasoma. Integument black, depressed apical tergal margins partly narrowly reddish translucent ( Fig. 9 View FIGURE 9 c). T1 very sparsely covered with long, erect yellowish-brown hairs, apical tergal hair bands very narrow; T2 with narrow basal hair band; terga apically not depressed ( Fig. 9 View FIGURE 9 c). Terga very densely and very finely punctate (i <0.5d), smooth and shiny between punctures ( Fig. 9 View FIGURE 9 c). Sterna with apical hair bands sparse and narrow.

Male. Bl = 7.0–9.0 mm. Head. Head wider than long. Integument black, except part of mandible dark reddishbrown. Face densely covered with long, yellowish to orange-brown, erect hairs. Malar area medially about as long as width of mandible base, sparsely punctate, smooth and shiny between punctures. Antenna black, ventrally dark brown. Mesosoma. Integument black. Mesoscutal disc smooth and shiny between punctures; disc sparsely punctate (i = 1–2d) with small punctures. Mesoscutellum anteriorly almost impunctate, with dense punctation apically, surface smooth and shiny. Mesoscutum, mesoscutellum, metanotum, mesepisternum and propodeum covered with long, orange-brown erect hairs ( Fig. 8 View FIGURE 8 b). Wings. Slightly yellowish-brown; wing venation dark brown. Legs. Integument black, tarsi partly dark reddish-brown. Vestiture yellowish-brown. Metasoma. Integument black except apical tergal margins narrowly reddish to yellowish translucent ( Fig. 10 View FIGURE 10 a). T1 entirely and disc of T2 covered with long, yellowish-brown, erect hairs; apical tergal hair bands narrow ( Figs 8 View FIGURE 8 b, 10a). Terga apically without depression. Terga with dense and fine punctation (i <0.5d), smooth and shiny between punctures ( Fig. 8 View FIGURE 8 b, 10a). Terminalia. Genitalia and S7 as illustrated in Figs. 8 View FIGURE 8 d, 10c.

Type material (6 specimens). Holotype, male, Thailand: Trang Na Yong, Khao Chong [99°47'22''E 07°33'02''N], 75 m, 27.I.2005, L. Packer [currently in PCLP, will be deposited at Queen Sirikit Botanical Gardens, Chiang Mai, Thailand, pending completion of ongoing studies].

Piluek [ RCMK]; 1 ♀, Chiang Mai, Huai Nam Dang NP Visitor centre, Malaise trap [98°36'24''E 19°18'48''N], 14–21.IV.2008, Anuchart & Thawatchai [ PCLP]; 1 ♀, Chang Mai, Doi Inthanon NP, Malaise trap [98°29'09''E 18°35'22''N], 2500 m, 1–8.XII.2006, Y. Areeluck [ RCMK]; 1 ♂, idem, 23.II.2007 [ RCMK]. Laos: 1 ♀, Giranville [102°46'E 18°22'N], 10.XI.1919, R.V. de Salvaza [ NHML].

Etymology. This species is dedicated to our colleague Laurence Packer, York University, Toronto, Canada, who has collected some of the specimens as a little “thank you” for years of fruitful collaboration.

General distribution. Known from tropical low lands up to 2500 m in Thailand and Laos.

Floral hosts. Unknown.

Remarks. At least some of the C. sodalis specimens reported from Yunnan ( China) ( Niu et al. 2013b) belong to C. packeri . The morphological differences between typical C. sodalis and those from Yunnan were interpreted as geographical variation. However, since both species are now known from the wider Chang Mai area ( Thailand) without showing significant intraspecific variation, their status as two different species is confirmed.
