Figures 50 , 57, 70, 89.

Axina basalis Schenkling, 1900: 389 . Lectotype. Female. Here designated. Type locality: Goyas, Bras, Donckier (Brasil) (SDEI). Paralectotypes. 2 specimens. Brazil: Estado do Goiás, collection date not noted, Donckier (BMNH, 1; SDEI, 1). 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. In the members of this species the midelytral fascia is triangular with the posterior margin of the fascia showing indentations. These characteristics will distinguish the members of this species from superficially similar specimens of A. spina , in which the posterior margin of the midelytral fascia in entire.

Redescription. Size. Length 13.0 mm; width 2.9 mm. Form. As in Fig. 89 . Color. Cranium, thorax, and legs castaneous; antenna testaceous; elytra bicolorous, mostly flavotestaceous, with 3 transverse castaneous fasciae, one at base, one at middle, and one preapical. Head. Cranium finely punctate, frons about as wide as length of antennal pedicel; EW/FW 60/12. Thorax. Pronotum finely punctate, with 2 tumescences, concave at middle; PW/ PL 130/175; elytra, asetiferous punctures substriate, punctures extend to elytral ½, width of interstitial spaces variable; EL/EW 550/110. Abdomen. Female pygidium slightly tapered to a blunt point; female visible abdominal sternite VI abruptly narrowed near posterior margin ( Fig. 57 ); aedeagus ( Fig. 50 ), phallobasic lobes uncinate, long, widely separated; phallic plates serrate on both margins; phallobasic apodeme abbreviated.

Variation. Size. Length 9.5–14.0 mm; width 2.3–3.9 mm. The castaneous transverse fasciae on the elytron disc vary in prominence.

Natural history. Specimens were collected in Bolivia during November and from Brazil during November through February, one specimen was captured with an ethanol baited flight intercept trap set in a stand of rose gum [ Eucalyptus grandis W. Hillex Maiden (Myrtaceae) ]. One specimen was collected from Brazil at 800 m.
