Figures 26, 60, 72, 116.

Type material. Holotype. Male. Type locality: Santa Cruz, Bolivia, S. C. Botanical Garden, 21-II-2004, Gino Nearns ( FSCA) . Paratypes. 7 specimens.

Diagnosis. Specimens of this species are superficially very similar to those of A. conspicua . But, in A. ignota specimens the edges of the phallic plates are serrate; they are smooth in specimens of A. conspicua .

Description. Size. Length 11.0 mm; width 2.3 mm. Form. As in Fig. 116. Color. Cranium, thorax, and legs castaneous, except basal region of femora testaceous; antenna testaceous; elytra bicolorous, mostly testaceous, humeral angle and region near mesoscutellum black, disc infuscated at middle and near elytral apex; abdomen testaceous. Head. Cranium finely punctate, frons slightly wider than length of antennal pedicel; EW/FW 50/18. Thorax. Pronotum finely punctate, with 2 tumescences, concave at middle; PW/PL 110/170; elytra, asetiferous punctures not striate, punctures extend to elytral posterior 3/4, interstitial spaces very wide; EL/EW 440/80. Abdomen. Female pygidium lunate, with transverse medial stalk ( Fig. 60); aedeagus ( Fig. 26), phallobasic lobes very short, contiguous; edge of phallic plates serrate; phallobasic apodeme abbreviated.

Variation. The available specimens are quite homogeneous.

Natural history. Specimens were collected in Brazil during November.

Distribution (for map see Fig. 72). This species is known from Brazil.

Etymology. The specific epithet, ignota , is a Latin name that stems from ignotus (= strange). I refer to the peculiar characteristic of the female pygidium.
