Type locality. Barbacena [Minas Gerais, Brazil].

Type repository. For A. volxemi : Muséum National d’Histoire Naturelle, Paris (lectotype examined, designated below). For A. squamifer : Muséum d’Histoire Naturelle, Geneva, Switzerland (examined).

Redescription. Length 5.0-6.0 mm, oblong, moderately convex, subshiny; glabrous, at most elytra with short, sparse pubescence near apex in males. Reddish-testaceous, sometimes brown-yellowish (ab. squamifer Petrovitz, 1970 ), front, pronotal disc and elytral suture somewhat darkened; legs brownish; antennal club yellowish. Head with epistome nearly flat, superficially microreticulate, finely and sparsely punctured; clypeus subtruncate anteriorly, widely rounded at sides, thickly bordered, border somewhat more thickened anteriorly; genae acutely angulate, almost not ciliate, strongly protruding beyond eyes; frontal suture finely impressed, backward curved at middle; front relatively more shiny and more distinctly punctured. Pronotum somewhat transverse, feebly convex, dually punctured; large punctures, four to five times larger than small, lacking on disc and moderately denser on sides, mixed fine and sparse punctures regularly scattered throughout; lateral margins feebly rounded, thickly bordered; hind angles obtusely truncate, faintly inwardly sinuate; base feebly bisinuate. Scutellum narrow, apically acuminate, finely microreticulate, sparsely and nearly imperceptibly punctured. Elytra oval elongate, moderately convex; striae fine nearly indistinctly punctured; intervals distinctly convex on disc, nearly flat on preapical declivity, finely and sparsely punctured. Hind tibiae superior apical spur almost as long as first tarsal segment; latter longer than following three combined. Male: head and pronotum relatively more transverse, less convex and more sparsely punctured; clypeus faintly truncate anteriorly; fore tibiae more slender and more elongate; metasternal plate with spoon-shaped depression, feeble median longitudinal groove, coarsely punctured; aedeagus Fig. 21-22 . Female: head and pronotum relatively less transverse, more convex and more densely punctured: clypeus more distinctly truncate anteriorly; fore tibiae stouter and shorter; metasternal plate with deep median longitudinal groove, flat and nearly smooth.
