Amnestus basidentatus Froeschner, 1960 , p. 634–637

Diagnosis. The males of this species can be separated by the distinct subbasal spine on the ventral margin on hind tibia, coupled with short, ventral, subapical spine. Similar to A. pusio , but the characters of the legs separate both species.

Description. Color light brownish yellow, coria, legs, and labium slightly paler.

Length almost three-fourths width; clypeus slightly longer than juga; latter with four marginal pegs; surface, except clypeus, with coarse, crowded punctures. Rostrum reaching between middle coxae. Pronotum: Length less than two-thirds width; anterior margin virtually truncate, not concave; lateral margin weakly sinuate on basal third; transverse impression moderate, punctate; anterior lobe weakly tumid, with prominent punctures laterally, subapically, along midline and scattered over disc of calli; posterior lobe, except umbones, with close-set, moderate punctures. Hemelytron: Mesocorium with few discal punctures; exocorium abundantly punctate across full width. Propleuron: Prosternal carinae lower than rostral II, subrectangular. Legs: Hind femora ventrally near basal third with strongly oblique, stout spine slightly emarginate at apex; hind tibia ventrally with strong, subbasal spine in addition to median angulation ( Fig. 6o ); hind femora with subapical oblique spine simple, about half as high as femur. Length of body: female (1.93–1.96 mm), male (1.75–1.95 mm).

New records. Mexico: Campeche, Escarcega 7-VI-1962, Trap light, F. Islas S., 1 ♂. (NMNH).

Distribution. United States of America, Cuba, Mexico.
