Diagnosis. In A. pollex specimens the distal limit of the metatibia is dark, the limit is testaceous in superficially similar specimens of A. analis.
Description. Size. Length 8.0 mm; width 2.0 mm. Form. As in Fig. 105. Color. Cranium bicolorous, venter castaneous, frons testaceous; antenna testaceous; prothorax bicolorous, venter and pronotum sides dark castaneous, center of disc broadly testaceous; pterothorax, legs, except tarsi flavotestaceous; elytra bicolorous, humeral angle and epipleural margin brown, disc with faintly visible marking at middle and transverse fascia before apex; abdomen, 3 basal visible sternites brown, 3 apical visible sternites yellow. Head. Cranium coarsely punctate, frons wider than length of antennal pedicel; EW/FW 40/15. Thorax. Pronotum coarsely punctate at sides, finely punctate in middle, with 2 tumescences, slightly concave at middle; PW/PL 85/120; elytra, asetiferous punctures striate, punctures extend to elytral apical 3/4, width of interstitial spaces variable; EL/EW 360/70. Abdomen. Female pygidium emarginate (Fig. 64); aedeagus (Fig. 32), phallobasic lobes short, digitiform, nearly contiguous; phallic plates minutely serrate subapically; phallobasic apodeme abbreviated.
Variation. Size. Length 8.0–13.0 mm; width 2.0– 3.8 mm. The brown markings on the elytron disc vary in prominence.
Natural history. Specimens were collected from Argentina during January and February.
Distribution (for map see Fig. 71). This species is known from Brazil, Paraguay and Argentina.
Etymology. The specific epithet, pollex, is a Latin noun with the meaning of “thumb”. I refer to digitiform configurations of the phallobasic lobes.
