INTRODUCTION
Carpelimus species of the Palearctic and Afrotropical regions have already been described comprehensively (Gildenkov 2002, 2003a, 2003b, 2007a, 2007b, 2015, 2017). However, Carpelimus species of the Oriental bioge-ographic region prove to be significantly more diverse than previously thought, notwithstanding substantial achievements made in their study (Gildenkov 2015). New species previously unknown to science are still discovered regularly (Gildenkov 2018). This paper presents a description of three new species belonging to the subgenus Carpelimus. It should be noted that the subgenus Carpelimus is a monophyl-etic group; its representatives are mainly characterised by sclerotised tooth-like structures in the internal sac of aedeagus (Gildenkov 2003a, 2007a, 2015). All three species are very similar to a widespread species Carpelimus (s. str.) planicollis (Bernhauer, 1902) and almost identical to it (as well as among each other) in colour, size, punctation of the body surface and depressions on the pronotum disc. The only clear distinctive characteristic of the examined species is their aedeagus structure.
Abbreviations used to indicate places where the examined material is deposited are as follows:
cMG — private collection of Mikhail Gildenkov, Smolensk, Russia; cPB — private collection of Petr Bañar,
Stráznice, Czech Republic; FMNH — Field Museum of Natural History, USA;
NKME — The Naturkundemuseum Erfurt, Germany.
Labels are presented as recorded from the original ones. This study implements general methods of insect taxonomy; dissection, measurements and drawings were performed using a MBS-10 microscope equipped with an eyepiece micrometer and a measurement grid. Genitalia specimens were treated with a 10% potassium hydroxide (KOH) solution and mounted with Euparal.
Length-to-width ratio of head, pronotum and elytra is given in the following standard
units: 7 standard units = 0.1 mm; thus, 1 standard unit constitutes approximately 0.014 mm.
Photos were taken on a Canon EOS 5D Mark III with a Canon MP-E 65 mm lens, using extended focus.

Description. Holotype. Body length approximately 3.0 mm. Colouration brown; legs and antennae yellow brown. Integument slightly shiny; body with short light-coloured hairs.
Head transverse, with a wide base; length to maximum width ratio (from posterior head margin to anterior clypeal margin) approximately 24 : 39. Neck constriction distinct. Eyes large, convex, occupying almost entire lateral part of the head. Temples almost absent, head widest across eyes (see fig. 1). Head surface with delicate, fine and dense punctation. Diameter of punctures about 4.0 times smaller than an eye facet. Distance between punctures significantly smaller than their diameter, interspaces smooth, slightly shiny. Antennae long, antennal segments 1-11 elongate. Last three segments more massive than others and form a loose club (see fig. 1).
Pronotum widest at about basal 2/3, then narrowed. Lateral margins form a notch, and then broadly rounded (see fig. 1). Length

to maximum width ratio of pronotum aproxi-mately 32 : 47. Pronotum surface with delicate, fine and dense punctation. Diameter of punctures about 4.0 times smaller than an eye facet. Distance between punctures significantly smaller than their diameter, interspaces smooth, slightly shiny. Pronotal disc with two pairs of distinct symmetrical depressions and one oval depression near apex along midline. Base of pronotal disc with narrow, crescent-shaped depressions separated by a medial ridge. Central part of pronotal disc with oval depressions fused across midline into a single butterfly-shaped depression (see fig. 13).
Elytra. Length to combined width ratio approximately 49 : 55. Elytra with rather delicate, fine and dense punctation. Diameter of punctures about 1.5 times smaller than an eye facet. Distance between punctures slightly smaller than their diameter, interspaces smooth, slightly shiny.
Abdomen delicately shagreened.
Aedeagus with characteristic structure (see figs. 2, 7, 11).
Female. Sexual dimorphism absent; female morphologically similar to male. Sper-matheca with a characteristic structure (see fig. 3) for representatives of the subgenus Carpelimus (Gildenkov 2007a, 2015).
Remarks on diagnosis. This species is very similar in its colouration, body size, punctation and form of pronotum to related Carpelimus (s. str.) planicollis (Bernhauer, 1902), C. raptius sp. nov. and C. taitungensis sp. nov. (habitus as in fig. 1). The new species can be clearly distinguished only by aedeagus structure (see figs. 2, 4-14).
Distribution. Vietnam, Thailand and Malaysia.
Etymology. From Latin communia ("common"); the name reflects that the species is widespread.
