Axina centrimaculata Schenkling, 1900: 288 . Lectotype. Female. Here designated. Type locality: Goyaz, Brasilia, Donckier (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. Its comparatively small size (length about 6 mm), the round testaceous marking on the basal ½ of the elytral disc along with the broad obliquely positioned macula behind the middle of the elytral disc are characteristics that will distinguish the members of this species from superficially similar and larger (about 11 mm) specimens of Axina bifasciata (Chevrolat) .

Redescription. Size. Length 6.0 mm; width 1.5 mm. Form. As in Fig. 93 . Color. Cranium castaneous; antenna testaceous; prothorax bicolorous, venter testaceous, pronotal sides dark castaneous, pronotal middle light castaneous; elytra bicolorous, disc mostly castaneous, large round testaceous marking in elytral basal ½, each elytron with wide obliquely position macula behind middle, and apical 1⁄5 th testaceous; legs bicolorous, distal ½ of femora and proximal ½ of tibiae dark brown, remainder of legs testaceous; abdomen flavotestaceous. Head. Cranium finely punctate, frons wider than length of antennal pedicel; EW/FW 33/15. Thorax. Pronotum finely punctate, with 2 tumescences, narrowly concave at middle; PW/PL 67/90; elytra with asetiferous punctures substriate, punctures extend slightly beyond elytron middle, width of interstitial spaces varies; EL/EW 150/50. Abdomen. Aedeagus ( Fig. 47 ), phallobasic lobes very short, contiguous; edge of phallic plates minutely serrate; phallobasic apodeme abbreviated.

Note. Previously A. centrimaculata was considered a synony of Axina bifasciata (Chevrolat) . I consider it a valid species and here revalidate the species status.

Distribution (for map see Fig. 70 ). In addition to the lectotype, I examined one specimen from: Brazil: Estado do Mato Grosso, Corumba, collection day and collector not noted. Specimens are deposited in: FMNH and MNHN.
