Axina nigrifrons Schenkling, 1906: 253 . Lectotype . Female. Here designated. Type locality: Puerto Cabello (Venezuela) (SDEI). Paralectotype . One specimen. Venezuela : Estado de Carabobo , Puerto Cabello (SDEI). Corporaal 1950: 98 . There is indication that Schenkling examined more than one specimen in his description of this species, but he did not select a holotype , therefore, I invoke Recommendation 73F of the ICZN (1999) and designate a lectotype for this nominal species. Diagnosis. The elytral apex is obtuse in specimens of this species, which is not the case in superficially similar specimens of A . acutipennis , in which the elytral apex is subacuminate. Redescription. Size . Length 6.0 mm; width 1.3 mm . Form . As in Fig. 111 . Color . Cranium bicolorous, frons black, remainder flavotestaceous; antenna testaceous; thorax and abdomen flavotestaceous; elytra bicolorous, basal 1⁄5 and apical 1⁄5 black, remainder flavotestaceous; legs bicolorous, prothoracic femora flavotestaceous, basal ½ of mesothoracic and metathoracic femora flavotestaceous, remainder of femora and tibiae black, tarsi brown. Head . Cranium finely punctate, frons slightly wider than length of antennal pedicel; EW/FW 40/10. Thorax . Pronotum finely punctate, with 2 tumescences, concave at middle; PW/PL 98/130; elytra, asetiferous punctures arranged into striae, striated punctures extend to elytral middle, width of interstitial spaces variable, elytral apex obtuse; EL/EW 360/65. Abdomen . Aedeagus, phallobasic lobes very short and abruptly narrowed in distal ½, narrowly separated; phallic plates serrate, phallic apex extended; phallobasic apodeme abbreviated. Variation. Size . Length 6.0–9.0 mm; width 1.6–2.2 mm . There may be one or 2 dark spots between the black basal and apical elytral region, and the black portion on the apical 1⁄5 of the elytra may be faintly visible or reduced to a narrow fascia. Natural history. Specimens were collected in Bolivia during October through December, some at altitudes that range from 370– 430 m . Distribution (for map see Fig. 71 ). In addition to the types , I examined 20 specimens from: Bolivia : Departamento de Santa Cruz , Potrerillos del Guenda, 6-8-XII- 2011 , 400 m, Morris & Wappes; idem , 3-5-III- 2011 , 370 m, J.
