Figs 1–4 View Figs 1–2 View Figs 3–7 .

MATERIAL. Holotype, ♂, West Malaysia, Perak: with labels “W. MALAYSIA FELDA LASAH vill. env. 40 km NE of IPOH 13–21.iii.2001 R. Hergovits leg.” ( MMBC). Paratypes: 18♀♀ “W. MALAYSIA FELDA LASAH vill. env. 40 km NE of IPOH 13.–21.iii.2001 R. Hergovits leg.” (cPB; 2♀♀ — MMBC; 5♀♀ — cMG).

DESCRIPTION (holotype). Length 3.0 mm. Body colouration dark brown, with red tint; legs and antennae light brown. Integument slightly shining, body surface 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 23:38. Neck constriction prominent. Eyes large, convex, occupying almost entire lateral surface of head; temples weakly developed, eye diameter in dorsal view about 3 times as long as temple length ( Figs 1–2 View Figs 1–2 ). Head surface with very delicate, extremely fine and dense punctation. Puncture diameter more than 5 times as small as eye facet. Distances between punctures significantly smaller than their diameter, interspaces smooth, slightly shining. Antennae not completely preserved in holotype ( Fig. 1 View Figs 1–2 ), only 4 and 5 first segments present on left and right antennae, respectively. In paratype (female) antennae similar in morphology ( Figs 1–2 View Figs 1–2 ), with length of all segments significantly exceeding their width ( Fig. 2 View Figs 1–2 ). Pronotum heart-shaped ( Figs 1–2 View Figs 1–2 ), widest about 2/3 its length from base, then narrowed. Lateral margins serrated ( Figs 1–2 View Figs 1–2 ). Ratio of pronotum length to its maximum width about 33:49. Surface of central part of pronotum with very delicate, extremely fine and dense punctation, near lateral margins surface of pronotum densely shagreened. Puncture diameter more than 5 times as small as eye facet. Distances between punctures significantly smaller than their diameter, interspaces smooth, slightly shining. Pronotal disc with two pronounced symmetrical longitudinal parallel depressions and 1 weak unpaired depression along midline near apex ( Figs 1–2 View Figs 1–2 ).

Ratio of length of elytra to their combined width about 52:56. Elytra with weak longitudinal depressions along suture ( Figs 1–2 View Figs 1–2 ). Surface of elytra with rather delicate, fine and dense punctation. Puncture diameter about 1.5 times as small

Abdomen delicately shagreened.

Aedeagus of characteristic structure ( Fig. 3 View Figs 3–7 ).

Female. Sexual dimorphism absent, female morphologically similar to male. Spermatheca of characteristic structure ( Fig. 4 View Figs 3–7 ).

COMPARATIVE REMARKS. The new species is similar in size to Carpelimus (s. str.) magnus Gildenkov, 2014 that lives in Indonesia and Philippines [Gildenkov, 2014c, 2019b], but differs from this species in having a lighter colouration, slightly more pronounced temples, wider pronotum with serrated lateral margins and elytra with a significantly finer punctation; clearly differs in the structure of the aedeagus ( Fig. 3 View Figs 3–7 ).

DISTRIBUTION. Malaysia: Malacca.

ETYMOLOGY. From Latin “pulchram, pulchrå” (beautiful, fine); the name refers to the external appearance of the beetle: its large size, a rather bright colouration and wide pronotum with serrated margins.
