Holotype: INDONESIA • ♂; Forest, Gunung Tambusisi, 1300 m. asl, Central Sulawesi Province, Indonesia; June 2022; Rizki Loulembah leg; MZB.Cole.195753. Paratypes: INDONESIA • 1 ♀; same data as for holotype; MZB.Cole.195754. Diagnosis. This new species can be distinctly distinguished from other species of Trachelophora by its peculiar elytral and body pubescence, puncture pattern, and color (Fig. 8). Male genitalia characterized by an elongate, slender tegmen; narrow parameres with dense apical setae; a tubular median lobe gradually tapering toward the apex, its surface distinctly wrinkled by fine membranous folds; and a pair of dark, strongly sclerotized, medially directed hook-shaped endophallic sclerites at mid-length (Fig. 9 M – T). Description. Male. Body elongate, robust; Body length 21.7 mm, body width 6.2 mm. Head, pronotum, prosternum, meso- and metasternum dark brown; antennae, elytra, and legs reddish brown; venter (excluding ventrites) dark brown to nearly black; ventrites reddish brown. Body surface clothed with irregular patches of yellowish tomentum; integument coarsely and densely punctate throughout (Fig. 8 A – H). Head slightly convex, longer than wide, narrower than pronotum; integument shiny black to dark brown. Surface strongly sculptured, coarsely and densely punctate; punctures mostly umbilicate. Pubescence consisting of short, dense, recumbent yellow-ochre tomentum, arranged in irregular patches on frons and vertex; remaining areas with sparse pubescence to nearly glabrous. Frons trapezoidal, wide, moderately convex; surface deeply and irregularly punctate, punctures umbilicate, dense throughout. Pubescence dense, yellow ochre, forming tomentose patches laterally and along the inner eye margins; median area glabrous and glossy. Median groove present as shallow, short impression, obsolete toward clypeus. Clypeus short and broad; surface shiny. Pubescence reduced, with scattered short recumbent setae; anterior margin bearing fringe of longer, pale yellowish, suberect setae, forming a conspicuous fringe. Genae short; surface coarsely punctate; pubescence present as dense ochre tomentum adjacent to eyes. Antennal tubercles distinct, moderately raised, separated by narrow median area; surface strongly punctate. Pubescence reduced on tubercles, with sparse short recumbent setae. Vertex broad, slightly convex; sculpture similar to frons, coarsely and densely punctate; Pubescence consisting of irregular ochre-yellow tomentose patches, denser laterally, sparser medially. Eyes large, strongly convex, coarsely faceted; inner margins distinctly emarginate. Surrounded by dense ochre tomentum contrasting with glossy black integument. Antennae (Fig. 8 A) clavate, long, ~ 2 × as long as elytra, reaching elytral apex at base of antennomere VIII; scape stout. Antennomeres clothed with short, dense, recumbent pubescence, except the scape, pedicel, and antennomere III, which are more sparsely clothed with pubesceence; each segment with few longer, white setae.

Prothorax (Fig. 8 A) trapezoidal, slightly longer than wide; disc moderately convex; surface coarsely, densely punctate; punctures deep, round to slightly umbilicate, imparting strongly rugose appearance. Lateral margins weakly angulate, each side with short, conical lateral spine near midlength. Anterior margin slightly narrower than posterior; posterior margin nearly straight, with distinct transverse basal groove. Surface clothed with short, dense, recumbent grayish to yellowish pubescence, forming irregular pale patches laterally and basally, partially obscuring integument. Scutellum (Fig. 8 A) small, short, semicircular, slightly convex; surface finely punctate, clothed with short, recumbent pale pubescence, partially obscuring the integument. Elytra (8 A, C) elongate, distinctly longer than combined pronotal length; subparallel-sided in basal half, gradually narrowing toward apical third; disc moderately convex basally, slightly flattened toward apex. Humeri moderately developed, rounded. Basal margin slightly raised; sutural line distinct, narrow throughout. Surface strongly, densely punctate; punctures coarse, deep, mostly round to slightly polygonal, separated by narrow interspaces, imparting distinctly rough, areolate appearance; punctures becoming slightly smaller and shallower toward apical third. Pubescence short, dense, recumbent, grayish to yellowish, forming irregular pale patches on disc and laterally, partially obscuring the reddish-brown to dark brown integument. Epipleura oblique, narrow, distinct, clothed with grayish to yellowish pubescence. Apical third of elytra gradually tapered to apex, apices rounded; sutural angles slightly produced; outer apical angles rounded, without distinct spines. Prosternum (Fig. 8 B, C) shiny, sparsely clothed with pale pubescence; prosternal process moderately narrow between procoxae, distinctly separating them; apex slightly expanded and rounded. Procoxal cavities large, rounded, distinctly separated by prosternal process, posteriorly open; procoxae prominent, area surrounding ventral surface with dense pale pubescence. Mesosternum, mesosternal process, mesepisternum, mesepimeron, metepisternum, and metepimeron (Fig. 8 B, C) densely clothed with short, grayish to yellowish pubescence; metasternum sparsely clothed with short grayish to yellowish pubescence and setae. Prosternum finely to moderately punctate, punctures small and shallow, sparse to moderately dense; mesosternum very narrow, appearing impunctate except for a distinct deep transverse depression; metasternum moderately punctate in anterior half, punctation becoming progressively finer and sparser posteriorly. Ventrite I finely punctate, ventrites II and III with punctation gradually reduced, ventrites IV and V with punctation weak to nearly obsolete. Femora sparsely clothed with short, recumbent grayish to yellowish pubescence and very sparsely with long, recumbent white setae.

A few longer white setae present among punctures. Head (Fig. 8 E, H) finely to moderately punctate; punctures relatively dense, round, shallow to moderately deep, partly concealed by pubescence. Pronotum with round to slightly irregular punctures, moderately deep and relatively dense, giving a coarse surface; punctation nearly uniform across disc. Elytra strongly and densely punctate; punctures round, deep, and very closely spaced, nearly contiguous, producing a coarse, granulose appearance. Punctation relatively uniform from base to near apex, slightly weaker toward apical region. Integument ventrally yellowish brown to pale brown, with some areas slightly darker (Fig. 8 E – H). Pubescence short, recumbent, cream to pale yellow, moderately dense, and evenly distributed, with a few scattered white setae. Surface distinctly punctate; punctures round, moderately dense on thorax, finer and slightly sparser on abdomen (Fig. 8 E – H). Remarks. Several body parts were already damaged when the first author (FF) received the specimens from the field. In the holotype male, the right protarsus and middle leg were broken, the right antenna lacked antennomeres V – XI, the left antennomere XI was detached, and the elytral apex was broken. The abdomen of both male and female specimens appeared damaged, possibly due to parasitic infestation. During subsequent handling, the head and prothorax of the holotype became detached and were reattached with white emulsoid glue. Consequently, some pubescence on the antennae, elytra, metaventrite, and legs was abraded, obscuring several morphological characters. In an additional female specimen, the head had been detached prior to examination, with glue remnants visible between the head a
