Orthomus abacoides (Lucas, 1846)

Figs 51–55.

Body size large, 10.4–12.4 mm, dorsum from to black dark brown, antennae and tarsomeres red brown, femora and tibiae darker. Male shiny, female less shiny with very fine microreticulation. Eye moderately convex, tempora oblique.

Anterior angle of pronotum advanced ahead, well-marked; pronotum more narrowed forward, maximum width at middle (Fig. 51), from here slightly arcuate backward; posterior basis with few and fine punctures, inner fovea linear, outer fovea shallow, basis not emarginate; posterior angle almost straight and without tooth.

Elytra almost parallel with small tooth at humerus and clearly sinuate preapically when the epipleura meets dorsum; striae deep, smooth or with insinuated punctures; discal pores on stria 3, intervals almost flat; parascutellar stria normally developed, with proximal hairy pore.

Ventral segments with punctures, isolated or rugose (Fig. 52). Prosternal process somewhat truncate projected backward in acute ridge. Metepisterna longer than wider (L/ W 1.3). Male mesotibia regularly dilated to apex, metatibia not crenulate.

Apical shaft of median lobe of aedeagus long, asymmetrically sinuate and deviated to the left (Fig. 54), truncate at tip; in lateral view moderately arcuate ventrally (Fig. 53). Female genitalia as described above (Fig. 55).

The species is found in NW of Algeria in the region of Oran and Mostaganem, some individuals have been found in ports of south France (Marseille), surely imported. It might be found in Morocco, in the littoral near the frontier with Algeria.
