Diagnosis.The male of this species can be recognized by the presence on the hind femur of a ventral, subapical spine which is more than one-third as long as the tibia. The female is marked by the presence of a flattened, polished, glabrous area on the middle of the last sternite and the presence of a short, oblique, subapical spine on the ventral margin of the hind femur. Body length 2.08 to 2.66 mm. General coloration yellowish tan, coria, legs, and rostrum usually paler. Head. Tylus longer than juga; latter with four marginal pegs becoming finer toward eye; surface except tylus, roughly punctuate; rostrum reaching bases of hind coxae. Pronotum with transverse impression distinct, marked by regular row of coarser, closer punctures; anterior lobe with coarse punctures in three or four rows laterally and subapical, and along midline and scattered over calli; posterior lobe, except umbones, abundantly punctuate. Mesocorium discally with single, irregular row of fine punctures; exocorium punctuate for full width. Prosternal carina almost as high as rostral segment II, abruptly terminated posteriorly. Fore femur ventrally with submedian spine very short, simple; fore tibia with two prominent spines on lower edge. Old records.Specimens intercepted in Texas, labeled “ Guatemala” ( Froeschner 1960).
