( Fig. 12 )

Odontolochus setulosus Endrödi, 1964: 377 –379. Dellacasa 1988: 276 (catalog).

Material examined. Holotype male, [ The Democratic Republic of the Congo] 'Musee du Congo, Haut-Uele, Tuku, 27.III.1919, P. Van den Plas'/, ' Odontolochus setulosus Endr.', ( MRAC); paratype (1) Uele, Dingila, 1.V.1933, H.J.Bredo ( MRAC).

Other specimens (1). Central African Republic: Bambari, II.1964, G. Pierrard ( MRAC).

Diagnosis. Clypeal upper edge narrowly reflexed, surface of head with distinct, smooth frontal suture and close, slightly rugose punctures. Pronotum converging only in basal third, ( Fig. 12 ) surface with shallow median line and shallow lateral fossulae. Elytral striae deep with large, deep, crenate punctures, each puncture with fine granules on each side; all intervals similarly developed, median carina sharply defined with single row of short, semi-erect setae.

Description. Length 3.0–3.5 mm. Body dark castaneous to piceous, dull, elytra setigerous. Clypeal upper edge narrowly reflexed, surface of head with distinct, smooth frontal suture and close, slightly rugose punctures. Pronotum not strongly elevated medially, converging only in basal third, anterior angles obtusely rounded, side deeply excavate, then sinuate to wide excavation ended by acute but not dentate basal angulation; surface with shallow median line and shallow lateral fossulae, punctures coarse, uniformly distributed, separated by one their diameter or less. Elytra nearly parallel-sided, humeral denticles very small; striae deep with large, deep, crenate punctures, each puncture with fine granules on each side; all intervals at the same level, tectiform, median carina sharply defined with single row of short, semi-erect setae. Ventral surface alutaceous; mesosternal median area triangular in shape, with few fine punctures at base, lateral furrows deep; metasternum slightly concave, discal punctures moderate, close, lateral area with twice larger punctures; abdominal sternites coarsely fluted along sutures with quadrate spaces between costulae, surface punctate; disc of pygidium eroded with longitudinal carina. Femora narrow, parallel-sided; protibia with three normal lateral teeth in both sexes; metatarsus long, basal metatarsomere twice as long as upper tibial spur and subequal in length to three following tarsomeres combined.

Male. Disc of pygidium longer than in female.

Remark. Odontolochus setulosus is the only species of the genus with distinctly setose elytra.

Distribution. The species is known from Central African Republic and The Democratic Republic of the Congo.
