Description

Amnestus pallidus Zimmer

Annectus [sic] pallidus Zimmer, 1910, p. 166

Diagnosis. The almost concolorous reddish brown head, pronotum, scutellum, and corium, plus the shorter rostrum which does not reach hind coxae, will separate this species from all with five marginal pegs on juga. Body length 2.08 to 3.26 mm. This species is often confused with A. spinifrons (Say), but the shorter rostrum, which here does not exceed the hind coxae, will separate the two; or in males, the absence of a midventral angulation on the fore tibiae will mark it from A. spinifrons.

Description. Tylus as long as juga, latter with five subequal, marginal pegs; surface, except tylus and apex of juga, coarsely punctuate; rostrum attaining middle of metasternum. Pronotum. Anterior margin shallowly concave, almost straight across; lateral margin straight on basal half; transverse impression obsolete, marked by vague row of punctures; anterior lobe with three to four irregular rows of moderate to coarse punctures laterally, subapically and along median band, calli mostly polished, with few fine punctures discally; posterior lobe, except umbones, with widely scattered punctures. Hemelytra. Mesocorium with few scattered, obsolete punctures discally; exocorium abundantly punctuate across full width. Prosternal carina lower than rostral segment II, rounded. Legs. Fore femora ventrally with premedian spine strong, oblique, unevenly bifid, and with blackish, subapical tubercle on posteroventral margin; fore tibiae neither angled nor spined mid-ventrally; hind femora not angled dorsally near apex, ventrally with subapical spine short, less than half height of femur.

Distribution. United States, Canada (Froeschner 1960). This species was cited erroneously from Mexico by Mayorga (2002).
