DIAGNOSIS
. This species (
Fig. 29–31
) is recognized by the relatively large size, yellowish- to reddish-orange head; the frons with a broad black mark on either side of median line; the black antennae; the mostly fuscous to black pronotum, with only the area between calli, a depressed spot behind each callus, and the posterior margin narrowly pale, and the straight lateral margins; the bright reddish-orange scutellum; and the dark hemelytra with a distinct bluish tinge.
It is most similar to
A. barrerai
in general appearance and male genitalia, but
A. barrerai
differs in having a more yellowish head that is only occasionally tinged with pale orange; the frons has only indistinct transverse brown markings on either side of the median line; the pronotum is paler yellowish brown, has distinct fine black spots on the calli, and lacks the distinct narrowly pale posterior margin; the lateral margins of the pronotum are flared posteriorly; and the scutellum is predominantly yellow or pale yellowish orange.
