(Figs. 97; 104–105; 129)
Female. Integument dark brown to greenish-gray. Body covered with dense and short greenish-gray setae. Frons rectangular, convex in lateral view; with frontal suture well marked, prolonged until occiput. Upper ocular lobes height almost half of the lower ocular lobe; distance between them two times width of lobe. Lower ocular lobe rounded; height subequal to malar area. Genae convergent.
Antennae (Fig. 97) reaching elytral apex approximately at antennomere VII. Scape covered with greenish-gray setae and slight spot of dark brown setae on apical region. Pedicel with one spot of dark brown setae on apical region. Antennomeres III–XI with one ring of dark brown setae on apical region, gradually longer on distal antennomeres; antennomeres III and IV with one sparse fringe of straight setae on inner surface.
Prothorax (Fig. 104) about 1.6 times wider than long; covered with short setae, golden and greenish; anterior margin almost one fifth narrower than posterior margin. Pronotum with three tubercles on disc: two median elevated, with rounded and glabrous apex; with the third tubercle on midline, situated posterior to median tubercles, smaller and with glabrous apex. Prosternal process width almost one third the diameter of one procoxa. Mesosternal process flat at posterior half and anterior margin decline at an angle of approximately 45° relative to mesosternum. Mesepisternum, mesepimeron and metepisternum covered with brownish setae.
Scutellum (Fig. 104) wider than long, subtriangular and apical margin rounded; with one slight longitudinal depression and dark brown stain on median region.
Elytra length about 3.5 times longer than prothorax; covered with mainly greenish-gray setae, with one dorsal median macula of white setae and irregular patches on sides and around the white central macula. Basal-crest (Fig. 104) elevated, with undefined tubercles; from crests, one dense “V”-shaped stain of dark brown setae; region between basal-crests with setae colored as the elytron. Epipleura setae coloration similar to dorsum. Apical margin of elytra truncate.
Legs entirely covered with yellowish-white setae. Anterior tarsi covered with golden setae. Tibiae with dense ring of dark brown setae on apical third. Tarsomere V (Fig. 105) bicolorous, base with golden setae and apex dark brown.
Abdomen entirely covered with brownish setae, denser on center-apical region of last sternite. Sternite V wider than long; almost as long as the length of sternites II, III and IV together.
Measurements (mm), female. Total length, 13.8; prothorax length, 2.7; prothorax maximum width, 4.4; elytral length, 10.3; humeral width, 5.8.
Etymology. Latin, aurum means gold, is allusive to golden setae covering the anterior tarsi.
Type-material. Holotype, female, Brazil, Espírito Santo, Linhares, XI.1973, B. Silva leg. (MNRJ) (Fig. 97).
Discussion. See discussion of A. subsellatus.
Geographical distribution. Brazil (Espírito Santo) (Fig. 129).
