MATERIAL. Holotype, ♂, West Papua “ IRIAN JAYA: 22.10.1993 Ob. Ibele-Tal . 2520m ca. 138°47´E 04°06´S, leg. M. Balke (42)” ( NHMW). GoogleMaps
DESCRIPTION (holotype). Length 1.9 mm. Entirely black; legs and antennae dark brown. Integument slightly shining, body with short, light-coloured hairs.
Head transverse, with a wide base, ratio of its length (from posterior margin of head to anterior margin of clypeus) to maximum width about 18:24. Neck constriction prominent. Eyes rather large, slightly convex. Temples well-developed, round, eye diameter in dorsal view barely exceeds temple length. Head about as wide across eyes as across temples ( Fig. 2 View Figs 1–3 ). Head surface with rather delicate, fine and dense punctation. Puncture diameter about 2.0 times as small as eye facet. Distances between punctures slightly smaller than their diameter, interspaces smooth, slightly shining. Antennae short, antennal segments 1–2 elongated; segment 3 triangular, about as long as wide; segments 4–10 strongly transverse; segment 11 elongated, conical. Last 3 segments more massive than others and form loose club ( Fig. 2 View Figs 1–3 ).
Pronotum widest about 2/3 its length from base, then narrowed. Lateral margins with small notch at base, then smoothly rounded ( Fig. 2 View Figs 1–3 ). Ratio of pronotum length to its maximum width about 21:27. Surface of pronotum with rather delicate, fine and dense punctation. Puncture diameter about 2.0 times as small as eye facet. Distances between punctures slightly smaller than their diameter, interspaces smooth, slightly shining. Pronotal disc with 2 pairs of rather weak, symmetrical depressions: 1 pair of deeper, widely crescent-shaped depressions, separated by medial ridge at base of disc and 1 pair of oval and more shallow depressions in central part of disc ( Fig. 2 View Figs 1–3 ).
Ratio of length of elytra to their combined width about 31:34. Scutellum with weak round depressions ( Fig. 2 View Figs 1–3 ). Surface of elytra with delicate, fine and dense punctation. Puncture diameter about 2.0 times as small as eye facet. Distances between punctures slightly smaller than their diameter, interspaces smooth, slightly shining.
Abdomen delicately shagreened.
Aedeagus of characteristic structure ( Figs 10–11 View Figs 7–19 ).
Female unknown.
COMPARATIVE REMARKS. The new species is similar to Carpelimus (Trogophloeus) notumus Gildenkov, 2019 , C. (T.) plenus Gildenkov, 2019, and C. (T.) vilisus Gildenkov, 2019 in the structure of the aedeagus [ Gildenkov, 2019a: 32, Figs 5–6 View Figs 4–6 , 8–11 View Figs 7–19 ]. It can be distinguished by dark colouration, weak depressions in the central part of the pronotal disc and transverse antennal segments 4–10 and clearly differs in the structure of the aedeagus ( Figs 10–11 View Figs 7–19 ).
DISTRIBUTION. Indonesia, Western New Guinea.
ETYMOLOGY. The name of the species is derived from the name of the river, in whose valley it was found.
