Hycleus arlecchinus Bologna sp. n. ( Fig. 3X )

Types. Holotype male ( SMWN) labelled “ Aurus Mts. , S., SE 2716 Cd, Diamond Area 1, 26–27 Oct. 1977, Coll. S. Louw M.L. Penrith; H35099” . 1 female paratype (CB) labelled “ Namibia, Hoogstepunt, Aurus Mts. , 25 Oct. 1977, V.S. Whitehead ” . 1 male and 2 females paratypes ( SMWN), labelled “ Heioab , Diamond Area 1, 25-26 Oct. 1977, Coll. S. Louw M.L. Penrith , H35062”. The male paratype of this last locality has one broken antenna and the second one broken and glumed on a separate label.

Type locality. The type locality (27.6500°S 16.3167°E) and all other known sites are located in the Karas region, Lüderitz district, Diamond Area 1, in the Namibian extension of the Succulent Karoo biome.

Diagnosis. One Hycleus species with 10 black antennomeres and the mesosternum intermediate in shape between the Mesotaeniatus and Mesoscutatus types, with narrow and small fore modified area, labial palpomere II scarcely modified, with a unique black elytral pattern composed by two longitudinal undulate stripes connected to apex.

Description. Body shiny and unicolor black, ventrally with very vague dark blue reflexions, elytra shiny anteriorly and subopaque posteriorly, brown-orange with black pattern ( Fig. 3X ) composed by two longitudinal stripes, one humeral and one sutural, connected to the wide black apex, the humeral one widened on the posterior third, forming a subrounded inclined spot, sutural one widened on fore third and on posterior third. Body setation black, denser and longer on ventral side of head, pronotum and metanotum and on fore legs; elytra glabrous with sparse microsetae. Maximal body length: 15–24 mm.

Head transverse, subrectangular, temples as wide as the maximum width at level of eyes; punctures deep, wide and relatively dense, denser and subrugose on frons, intermediate surface microreticulate; frons and occiput almost flat; eye subglobose, with antero-dorsal margin not sinuate; temples parallel, about as long as longitudinal diameter of eye. Clypeus narrower than interocular width, rounded on sides, convex and with same puncturation of frons, not punctate and shiny on fore third; fronto-clypeal suture well visible; labrum slightly longer than clypeus, fore margin slightly sinuate, punctures finer than on clypeus. Maxillary palpomeres subcylindrical, IV only slightly enlarged anteriorly, with black setae on the external side of apex of each palpomere (except IV), particularly on III; male maxillae not modified with stipes narrow and elongate in lateral view; II labial palpomere widened, last one short and stout; mandibles robust, curved in fore half, sharp at apex, slightly longer than labrum. Antennae ( Fig. 12D ) with 10 antennomeres, I–V shiny, VI–X opaque and microsetate; I slightly shorter than II–III together, II subglobose; III–V slender and subcylindrical, III slightly longer than IV–VI; VII–IX subtrapezoidal, apically widened on inner side, increasing in width and length from VII to IX; X at base as wide as IX but two times longer, the apical half evidently and conically narrowed, apex obtuse, without tracks of fusion of two antennomeres.

Pronotum subcampaniform, slightly longer than wide, wider than head, side slightly widened from base to middle and then evidently narrowing anteriad; fore portion transversally subdepressed; middle furrow extended only in middle, base shortly depressed just in front of mesonotum; puncturation similar than on head, but slightly sparse. Elytra parallel, dorsally convex, punctures similar in size to those of pronotum but shallower, denser on sides and on black parts, while inner orange-brown surface with micro-puntures and very short setae. Mesosternum ( Fig. 12E ) intermediate in shape between Mesotaeniatus and Mesoscutatus types, with narrow and small fore modified area, smooth and shiny; fore margins of mesepisterna well defined, narrow concave and evidently depressed, at the same level of the sclerite. Legs slender, both tibial spurs on all legs slender, external metatibal spur only slightly rounded at apex; ventral blade of claw regularly developed, scarcely curved.

Ventrites shiner with more scattered punctures and shorter but dense setae. Male penultimate ventrite widely arcuate on posterior margin, last one widely and scarcely emarginated. Gonoforceps slender in both lateral and dorsal views ( Fig. 12 A, 12B ); aedeagus ( Fig. 12C ) with two apical hooks, distal smaller and lesser inclined than prossimal.

Remarks. No species of the genus have a similar elytral pattern. Affinities of this species among those with a mesosternum Mesotaeniatus - type are totally unknown.

Etymology. The name of the new species refers to the elytral pattern, which is reminiscent of the clothes of Arlecchino, the Venetian “maschera”, as painted by Cézanne.

Distribution. SW Namibia .
