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.
