Pasteur Toegoe Java occ / Museum Leiden (Fig. 1 L, M). Diagnosis. (holotype, based on quality photographs, and modified from the original description) Male relatively large, length 25.0 mm, width 7.0 mm, with an elongate body and dark reddish-brown to dark brown integument densely clothed with short, recumbent pale ochraceous to creamy-yellow pubescence forming irregular tomentose maculae on the pronotum and elytra. Head slightly shorter than the pronotum, coarsely punctate, each puncture on the frons bearing a short pale seta; median groove distinct, deep on the frons, becoming shallow on the vertex, and extending to the clypeus; antennal tubercles well developed. Antennae slender; scape moderately thickened, coarsely punctate, each puncture bearing a short pale seta. Pronotum distinctly longer than wide, with a strong lateral spine on each side; disc densely punctate and pubescent. Elytra elongate, basally parallel-sided and gradually narrowed apically, densely punctate to granulate, clothed with fine, short, recumbent pale ochraceous to creamy-yellow pubescence, denser in irregular tomentose maculae but locally sparser in diffuse discolateral areas, exposing the dark reddish-brown integument and producing an irregular mottled appearance. Legs with clavate femora; venter uniformly pubescent. Male genitalia. Description based on a male specimen deposited in MZB. Tegmen (Fig. 9 A – D) elongate, approximately as long as the median lobe. Parameres (Fig. 9 A – C) symmetrical, broad basally, gradually narrowing toward the apex, separated by a narrow median emargination extending to ~ 1 / 3 of their length; apices broadly rounded, densely clothed with numerous short setae. Phallobase elongate, distinctly longer than the parameres. Median lobe (Fig. 9 E, F) elongate, nearly parallel-sided throughout most of its length, gradually narrowing toward the apex; apex narrowly rounded in dorsal view and distinctly curved ventral in lateral view. Remarks. Perroud (1855) described Trachelophora curvicollis based on a male specimen. Subsequently, Breuning examined male and female specimens housed in the NMB; the male specimen was identified as T. curvicollis (Fig. 1 F, G), whereas the female specimen was misidentified as T. lineata (Fig. 1 H, I). Distribution and habitat. Sundaland: Java, Sumatra, and Borneo. Trachelophora curvicollis has been reported from secondary forests, jungle-rubber, and agroforestry systems (Fahri et al. 2015, 2016).
