Description

Type material. Holotype, male (NHMB); Label 1: Laos-NE, Xieng Khouang prov., 19°38.2′N 103°20.2′E, Ban Na Lam Phou Sane Mt., 20.–30.v.2009, 1420m, D.Hauck leg.; Label 2: Secondary mountain forest, flight intercept trap, Laos 2009 Expedition, NHMB Basel, NMPC Prague.

Male: body length 4.3 mm from tip of head to tip of elytra; body reddish brown with the discs of the antennal club, elytra, ventrites and pygidium, lateral parts of head, pronotum and elytra, and basal two thirds of femora dark brown to black; dorsal surface of head, pronotum and elytra coarsely rugose, resulting in a dull appearance; antennal clubs and legs smooth and shining; all parts of the body equipped with long, mostly sparse pubescence with the exception of the mostly glabrous pygidium and abdomen. Head at frontal part with a shallow depression, bordered in front at the left and right side by the low but sharply raised anterior margin; vertex with a medial suture from the middle of the head to the posterior margin, cutting a longitudinal slit through a tubercle; the latter might represent an evolutionary remnant of a former gland pore, although no true orifice is discernible; between eyes a pair of ill-defined black colour patches which are located at the sites where tentorial pits or glandular openings are present in other species; hind margin of head slightly indented in the middle; temples broad, rounded, hardly projecting laterally beyond eyes in dorsal view; neck narrow, strongly constricted. Mouth of the “closed” type, i.e. maxillary and labial palpi cover the mouth opening from beneath; maxillary palpi with third from terminal palpomere large, compressed; terminal palpomere of labial palpi slightly compressed, of oval shape with acute tip. Antennae with compressed club; fore margin slightly convex, hind margin straight without traces of indentations; basal tooth large, without trichome; hind margin ventrally with a deep furrow from the basal tooth to short distance before apex; dorsal disc with a shallow, longitudinal depression.
