Trachelophora affinis Breuning 1982

Trachelophora affinis Breuning, 1982 Fig. 7 F – I Trachelophora affinis Breuning, 1982: 143 (original description, type locality: de Borneo: Poling near Ranau, Sabah. Type material examined. Holotype: ♂ (EUMJ), Trachelophora affinis mihi typ Breuning det. (handwritten with green ink and printed with black ink on a rectangular white label) / Trachelophora affenis sp. nov. Det. By Breuning, 1992 [misspelling of affinis] (printed in black ink on a rectangular white label) / (BORNEO IS.) Polling nr. Ranau Sabah, Malaysia 30. IV. 1980, M. & A. Sakai (handwritten and printed with black ink on a rectangular white label) / TYPE (printed with black ink on a rectangular red label) (Fig. 7 F – I). Diagnosis. (holotype, based on quality photographs, and modified from the original description) Male distinguished from all congeners by its small-sized body, length 15 mm, width 4 mm, dark brown integument largely concealed by dense, short, recumbent pale ochraceous to creamy-yellow pubescence, and irregular tomentose maculae on the pronotum and elytra. Head distinctly narrower than the prothorax, ~ 1 / 2 as long as the pronotum, with a very shallow median groove visible only on the vertex; genae as long as the lower eye lobes; eyes deeply emarginate, with large lower lobes. Antennae slender, with an elongate, distinctly clavate scape bearing several white ventral setae extending to antennomere III; pubescence forming alternating pale bands from the scape to antennomere IV and denser on the basal three-fifths of antennomeres V – VII. Pronotum transverse, bearing a strong acute conical lateral spine on each side. Elytra ~ 4 × as long as the pronotum, densely and coarsely punctate, punctures irregularly arranged; pubescence forming irregular tomentose maculae, including a distinct white macula at the apical third of each elytron; sutural carina weakly developed; apices individually obtuse. Remarks. This species is readily distinguished from all congeners by the combination of its small body size, transverse pronotum with strong acute lateral spines, very shallow median groove restricted to the vertex, distinctly clavate scape with white ventral setae, banded antennal pubescence, and elongate elytra with irregular tomentose maculae, including a distinct white apical-third macula and a weakly developed sutural carina.
