( Figs 4–5 )

Type Material: Holotype: PANAMA: Darien: Male. Cerro Chucanti, 15 km W. of Torti. 13–16 February, 2012 collected at mercury vapor light. W. H. Tyson (CASC); Paratypes: PANAMA: Darien: Female, same location and dates (WHTC); male, same data, collected by L. G. Bezark (LGBC).

Etymology. The species name cordiforme refers to the heart-shaped denuded area on the distal one third of the elytra.

Diagnosis. Two other species from Mexico are similar but differ as follows: A. yucatecus Chemsak and Noguera is found in cental Mexico and the denuded areas on the elytra are more oval, not cordiform, and are separated by pubescence. Also, the pronotum is sparsely covered with pubescence. A. albopilis Chemsak and Noguera is also similar but the denuded areas of the elytra are not heart-shaped and are separated from each other by a noticeable area of pubescence. The pronotum is sparsely to moderately marked with pubescence without any defined pattern.

Description. Male ( Fig 4 ). Integument reddish brown to brown. Legs slightly lighter in color. Antennae as long as or slightly longer than the body with small spines on segments 4–7 and some long hairs on the underside. Head with eyes widely separated. Pronotum rugose and covered with decumbent pubescence of a light grey-white color. A faint pattern exists on the pronotum around the small polished callus. Scutellum heavily clothed with whitish pubescence. Elytra heavily punctured. Humeri clothed with pubescence appearing as a small spot. The pattern of the elytra gives the impression of a denuded area shaped like a heart with only a faint line of pubescence along the elytral suture separating the two areas. White pubescence surrounds the denuded areas becoming denser as it approaches the denuded area. Apices emarginate-truncate without denticles. Underside is lightly clothed with pubescence and some flying hairs.

Female ( Fig 5 ). Similar to the male but with the last sternite rounded, not emarginate and less densely pubescent on the pronotum. Specimen is damaged and is missing bits of both antennae. The antennae probably do not reach the apex of the elytra.

Dimensions (in mm). male: total length from front of head to elytral apex 14; prothorax: length 2.5, width at middle 3.0; length of elytra 10.5, width at base 3.5; female 13.
