Diagnosis. From superficially similar specimens Axina heveli, A. acutipennis beetles differ by showing a full striate complement of asetiferous punctures on the basal ½ of the elytral disc, and the mesothoracic and metathoracic femora are mostly black. These femora are mostly flavotestaceous in A. heveli specimens. Description. Size. Length 11.0 mm; width 2.5 mm. Form. As in Fig. 119. Color. Cranium bicolorous, frons black, remainder light castaneous; antenna brown; thorax and abdomen light castaneous; elytra bicolorous, basal ¼ and apical ¼ black, remainder flavotestaceous; legs bicolorous, femora mostly black; tibiae and tarsi black. Head. Cranium finely punctate, frons slightly wider than length of antennal pedicel; EW/FW 50/20. Thorax. Pronotum finely punctate, with 2 tumescences, concave at middle; PW/PL 120/160; elytra, asetiferous punctures striate, punctures extend to elytral middle, width of interstitial spaces variable; elytral apex subacuminate; EL/EW 500/100. Abdomen. Aedeagus, phallobase tapered distally; phallobasic lobes very short and nearly contiguous; phallic plates serrate; phallobasic apodeme abbreviated.

Variation. Size. Length 7.0–11.0 mm; width 1.7–2.5 mm. Other than body size, the available specimens are quite homogeneous.

Natural history. The available specimens were collected from Bolivia during February and November one at 405 m another at 2,627 m.

Distribution (for map see Fig. 73). This species is known from Bolivia and Paraguay.

Etymology. The specific epithet, acutipennis, is a Latin compound name that stems from acuti (= sharp) and penna (= wing). I refer to the sharply tapered elytral apex.
