Aristolebia klimenkoi sp. nov.

( Fig. 2 )

Type material. Holotype female, labelled: “ MALAYSIA, N Borneo, Sabah, Keningau distr., Trus Madi Mt. , 1160m, 18.VII.2011, A. Klimenko leg.” ( DUBC).

Differential diagnosis. The new species is most similar to A. saluki sp.n. from India (Karnataka) in body size, shape and colouration. Easily distinguishable by red head and shallow, superficial striae of elytra.

Description. Body length: 12 mm; width of elytra: 5.1 mm. Width/length of pronotum: 1.62; length/width of elytra: 1.45.

Head red; labrum, anterior margin of clypeus and mandibles dark brown; labial palpus and maxillary palpus brown. Antennae black, except 3 basal antennomeres and base of 4 th yellow. Pronotum, elytra and lower surface pale yellow (The dark spot visible on the pronotum of the Holotype arose from the fact that it was slightly crushed). Legs pale yellow, with black knees and brown tarsa.

Eyes very large, semicircular, laterally remarkably protruding. Antennae slender and long, surpassing the base of the pronotum by five antennomeres. Three basal antennomeres glabrous. Labrum impunctate, with strong isodiametric microreticulation. Clypeus impunctate, in anterior half with distinct isodiametric microreticulation. Frons with short longitudinal impressions behind clypeal sutur e. Spar sely and fin ely pun ctur ed. Microreticulation very superficial, mostly obsolete, surface glossy.

Pronotum comparatively narrow. Anterior half semicircular, widest slightly in front of middle, moderately narrowed towards base. Anterior margin straight, apical angle widely rounded; lateral margin in apical half convex, in basal half roundly oblique, basal angles very obtuse, almost effaced. Both apex and base margined. Anterior transverse sulcus deep. Median line shallow, incomplete. Posterior transverse sulcus deep. Lateral margin anteriorly wide and flat, widened and widely explanate towards base, marginal sulcus sh allow, margin slightly upturned. Disk convex. Anterior lateral seta situated slightly behind anterior third, removed from margin, posterior seta situated at basal angle. Surface of disk smooth, without microreticulation, strioles or punctures; very shiny; with two symmetrical rounded fossa on the center of the disc.

Elytra wide, rather widened apically, widest approximately at apical third, upper surface convex. Humera evenly rounded, lateral margin almost straight. External apical angle and sutural angle both denticulate. Apex oblique and gently concave. Striae superficial throughout, weakly punctate; 4 th and 5 th striae slightly deeper on shoulder; in apical fourth of elytra between 7 th and 8 th striae inserted two irregular vestigial striae. Intervals flat. Third interval with 3 setiferous punctures, attached to the inner mar gin of th e 3rd stria. 16-17 mar ginal setiferous punctures present, series slightly interrupted in middle. Intervals with 1-2 irregular rows of sparse, fine punctures and with superficial, slightly transverse microreticulation, surface glossy. Wings fully developed.

Lower surface with sparse but elongate, slightly declined pilosity. Abdominal sterna with sparse and moderately long pubescence. Propleuron, mes- and metepisterna smooth.

Legs of average size, 4th tarsomeres of all legs widened, very deeply excised, with dense tarsal brush. Tarsal claws wide; very densely dentate with 14 teeth of about equal length on either side.

Male unknown.

Variation. Unknown.

Distribution. Malaysia, Borneo. Recorded only from the type locality.

Etymology. New species named after Alexey Klimenko (1970-2017), who was my friend and a famous collector of beetles.
