(Figs. 2, 6, 11–12)
Type material. Holotype: WEST MALAYSIA (Pahang/Selangor States): ♂, two labels: " MALAYSIA, / GENTING Highlands / # 49, 8 II 1998 / G. O'Reilly" [white, printed]; " Cephennomicrus / gentingensis m. / det. P. Jałoszyński, '14 / HOLOTYPUS " [red, printed] (MNHW).
Diagnosis. BL about 1 mm; pronotum with two lateral pairs of pits; each elytron with two macrosetae; aedeagus in ventral view gradually narrowing distally, with symmetrical internal armature containing a pair of large and mesally curved subapical plates each with bifid apex.
Description. BL 0.98 mm. Body of male (Figs. 1, 6) elongate and strongly convex, brown with slightly lighter vestiture.
Head broadest at large, strongly convex and coarsely faceted eyes, HL 0.15 mm, HW 0.25 mm; vertex and frons confluent and convex; supraantennal tubercles feebly marked. Punctures and setae on head dorsum very fine but discernible under magnification 80x. Antennae slender and with club composed of enlarged antennomeres X–XI, AnL 0.45 mm, antennomeres I–II and IV–IX elongate; III about as broad as long; X transverse; XI only slightly longer than X and about 1.2x as long as broad; antennomeres X–XI with several strongly erect, long setae among short and suberect basic setation.
Pronotum (Fig. 6) subrectangular, broadest near anterior fourth; PL 0.30 mm, PW 0.38 mm; anterior and lateral margins in anterior third broadly rounded, sides in posterior half distinctly concave; anterior corners visible only in anterodorsal view, distinct and sharp but with rounded tips; posterior margin slightly arcuate with short and shallow emargination in front of mesoscutellum; posterior corners nearly right-angled; pronotal base with two pairs of small but distinct pits. Punctures on pronotal disc as fine as those on frons and vertex; pronotal disc with very short but distinct sparse and nearly recumbent setae and erect macrosetae: two lateral pairs and one posterior pair in front of mesoscutellum.
Elytra (Fig. 6) oval, broadest anterior to middle; EL 0.53 mm, EW 0.45 mm, EI 1.17; humeral calli wellmarked, elongate. Punctures on elytra fine and inconspicuous; basic setation extremely short and nearly recumbent but discernible under magnification 80x, additionally each elytron with two lateral macrosetae. Hind wings well developed.
Legs moderately long and slender, unmodified.
Aedeagus (Figs. 11–12) in ventral view approximately drop-shaped, gradually narrowing distally; AeL 0.19 mm. Internal armature symmetrical, with a pair of large and mesally curved plates each with bifid apex; parameres slender and not reaching apex of median lobe, each with three apical setae.
Female. Unknown.
Distribution. Peninsular Malaysia, a border area between states Pahang and Selangor.
Etymology. Locotypical, after the Genting Highlands.
Remarks. No other species of Cephennomicrus has a pair of broad and apically bifid endophallic sclerites similar to those found in C. gentingensis.
