Aristolebia saluki sp. nov.

( Figs. 1, 4 )

Type material. Holotype male, labelled: “ INDIA, Karnataka, Shimoga distr., Sagara, Jog falls vill., 530m, 02-05.XI.2013, 14°13.240N, 074°48.471E, on light, S. Saluk leg.” ( DUBC) .

Paratype female: same label data (cAA).

Differential diagnosis. Rather large species (in genus), characterized by the yellow elytra and black head. Distinguished from other large species with yellow elytra A. rutilipennis Baehr, 2015 and A. rubiginosa Kirschenhofer, 2012 , by having a unicolourous yellow pronotum, differently coloured legs and differences in shape of pronotum and elytra.

Description. Body length: 12 mm; width of elytra: 5.8-6 mm. Width/length of pronotum: 1.53; length/width of elytra: 1.41.

Head, including clypeus and labrum, black; mandibles black with brown apex; gula, labial palpus and maxillary palpus yellow. Antennae black but three basal antennomeres and base of fourth yellow.

Pronotum, elytra and lower surface pale yellow. Legs uniformly pale red, with black knees.

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, polygon al micr or eticulation, tr an sver se medially. Clypeus barely punctate, with distinct isodiametric microreticulation. Frons with shallow longitudinal impression behind clypeal suture and a shallow, irregular impression in middle, with shallow wrinkles and rather sparse punctures. Microreticulation fine and very superficial, isodiametric, obsolete on the frons, surface glossy.

Pronotum comparatively narrow. Anterior half semicircular, widest slightly in front of middle, moderately narrowing posteriorly. Anterior margin straight, apical angle broadly rounded; lateral margin in apical half convex, in basal half oblique and almost straight, basal angles obtuse. Both apex an d base margin ed. An ter ior transverse sulcus ondulate. Median line moderately shallow, incomplete. Posterior transverse sulcus deep. Lateral margin anteriorly wide and convex, widened and widely explanate posteriorly, marginal sulcus shallow, margin little upturned. Disk convex.Anterior lateral seta situated slightly behind anterior third, removed from margin, posterior seta situated at basal angle. Surface of disk with irregular, transverse strioles and punctures; microreticulation very fine and superficial, glossy.

Elytra wide, rather widened towards the apices, 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 deep throughout, crenulate; fifth stria very deep on shoulder, seventh stria interrupted on shoulder, two additional striae inserted between 7th and 8th striae in apical third of elytra. Intervals flat. Third interval with four setiferous punctures, attached to the inner margin of the third stria. 17-18 marginal setiferous punctures present, series slightly interrupted in the 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 dense and 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 very densely dentate with 10 long teeth of about equal length on either side. Mesotibiae of males not modified at inner surface.

Aedeagus ( Fig. 2 ) moderately elongate, straight. Apex short and wide, gently downturned. Internal sac with sclerotized semicircular plate and three groups of relatively long spines. Parameres asetose, the left one elongate, the right one odd-shaped.

Distribution. India (Karnataka).

Etymology. The name is a patronym in honour of Sergei Saluk (Minsk, Belarus).
