Figs. 1 A–C; 2A–C
Type material. Holotype: male, labeled “Sicilia, Trapani, R. N. O. “Zingaro”, 700m ca., 26–29.III.2006, leg. Baviera C.” (CMME) (Fig. 1). Paratypes: 1 male, 2 females, same data as holotype. 1 female with terminalia extracted and mounted in Euparal (CMME, LMC, CBC).
Diagnosis. Similar to O. striatosetosus Boheman yet differing from it by the rostrum which is longer than wide, larger punctures on the pronotum, less rounded sides of the prothorax, longer antennae, a more rounded apex of the mesophallus and a much more abruptly curved spermatheca.
Description. Holotype – Body length 7.5 mm, maximum elytral width 3.5 mm. Body black, tibiae, tarsi, and antennae brownish. Rostrum as long as wide. Posterior margin of epistome widely rounded to obtusely angled, slightly keeled. Frons anteriorly folded downwards, smooth, shiny, with shallow punctures. Lateral sides of frons convergent towards the eyes, with quite deep punctures and a transverse impression in the anterior half. Antennal scape slightly clavate and curved; funicular joints as follows: I 2.3x as long as its apical width, II 3x as long as its apical width, III 1.8x as long as wide, IV 1.5x as long as wide, V and VI 1.3x as long as wide, VII 1.5x as long as wide; club fusiform, 2.2x as long as wide, as long as funicular joints V to VII combined. Head 1.8x longer than wide, eyes feebly convex, inter-ocular space 0.5x as wide as width of rostrum at antennal insertion, slightly wider than maximum width of an eye. Head and rostrum puncturated, each puncture with a white, recumbent, 5– 6 x longer than wide seta. Pronotum (Fig. 5 C) as wide as long, lateral margins strongly rounded, maximum width behind its midpoint, much narrower apically than at base, dorsal surface slightly convex. Disc with punctures mesally directed, larger on central area than on sides, intervals about as wide as half diameter of punctures; granules mesally directed, similar in size to lateral punctures; punctures and granules with semi-erect white setae, 2– 3 x longer than wide. Elytra (Fig. 6 C) 1.37x longer than wide, elliptic, sub-parallel sided; punctures of striae slightly oval and sharply delineated, each with a small white seta on anterior margin. Intervals of striae smooth and shiny, 1.5x as wide as striae, with a median row of small punctures, each with a white seta, 1.5x longer than wide, inserted at a 45° angle; with scarce groups of golden hair-like setae. Urosternites smooth and shiny, scarcely puncturated, each puncture with a seta 2– 3 x longer than wide; 5th anal urosternite with thin striae on its anterior half. Femora unarmed, fore tibiae slightly expanded apically. Aedeagus quite regularly curved dorsoventrally, basal apodemes slightly longer than mesophallus, apex rather evenly rounded, only slightly less so in the middle (Fig. 1 B–C).
Paratypes. The length of paratypes varies from 6.5 to 8 mm. The punctures of the strial intervals are deeper in some specimens. The lateral sides of the elytra are more rounded and the 5th anal urosternite lacks striae in females. The spermatheca is very abruptly curved in the middle, the spiculum ventrale is palette-like and setose at the apex, apodeme about 3 times longer than the expanded apex (Fig. 2 B–C).
Etymology. The new species takes its name from its type locality: Zingaro (= gipsy) Natural Reserve. Distribution. The new species is known only from the Natural Reserve of Zingaro; all samples were collected on the ground under stones.
