The males of this group are characterized by their large body size (> 1 cm ), malar area at least half as long as width of mandibular base, broad facial fovea, metasomal terga densely covered with light brown long erect hairs, lack of white apical tergal hair bands, and trilobate S7. Colletes kinabalu differs from the other species of the group by its smaller size, the dark brown to blackish pilosity on the dorsal side of the body ( Fig. 1a ) (yellowish to reddish-brown in the other species), apical sternal hair fringes generally short and slightly longer medially ( Fig. 2e ) (much longer in the other species), the unusually long gonostylus ( Fig. 2a ), and the characteristic shape of S7 ( Fig. 2c–d ) [for shape of S 7 in related species see Noskiewicz (1936) and Stephen (1954) ]. The female of C . kinabalu is unknown. DESCRIPTION: ♂ : Body length 11.0 mm. Head slightly wider than long (width:length 1.04). Integument black except part of mandible, clypeus, and malar area partly dark reddish-brown. Face except clypeus densely covered with long, dark brown, erect hairs. Lower face laterally densely covered with short whitish-grey hairs ( Fig. 1b–c ). Malar area medially about 1.2 times as long as width of mandible base, finely punctured ( Fig. 1c ). Facial fovea broad, about twice as broad as width of antenna. Antenna black, ventrally dark reddish-brown. Mesosoma integument black. Mesoscutal disc between punctures smooth and shiny; disc densely punctate (i = 0.5d). Mesoscutellum densely punctate but anteriorly less so, surface smooth and shiny ( Fig. 1d ); mesoscutum, mesoscutellum, metanotum, mesepisternum, and propodeum covered with long, erect dark brown to blackish hairs ( Fig. 1a, d ). Wings distinctly yellowish-brown; wing venation brown ( Fig. 1a ). Legs with integument black to dark reddish-brown. Vestiture dark brown. Hind basitarsus as in figure 2f. Figure 1.

Metasoma integument blackish to dark reddish-brown, depressed apical tergal margins reddish to yellowish translucent ( Fig. 1e–f ). T 1 sparsely covered with long, erect dark brown to blackish hairs ( Fig. 1f ); remaining terga covered with short, erect blackish hairs; T 1 apico-laterally with narrow and thin hair band. Apical tergal depressions broad and deeply depressed, on T 1 medially about three times as wide as laterally ( Fig. 1f ). T 1 with dense and relatively coarse, irregular punctation (i = 0.5d), between punctures smooth and shiny, on following terga puncture of disc successively smaller ( Fig. 1e–f ). T 7 broadly rounded, without emargination or spines. Sterna with dense apical hair bands, medially broadened ( Fig. 2e ). Genitalia and S7 as illustrated ( Figs. 2a–d ). Figure 2.

Scale bars = 1 mm. ♀ : Unknown. HOLOTYPE : ♂ , “Kinabalu, BrNo [British North] Borneo” ( ANSP ). DISTRIBUTION: Only known from Mount Kinabalu, Sabah , Malaysia . ETYMOLOGY: The species is named after Mt. Kinabalu (noun in apposition), the only known locality where it has been found so far.
