Axina bifasciata (Chevrolat), 1876

Figures 69 , 84 .

Priocera bifasciata Chevrolat, 1876: 9 . Holotype. Female. Type locality: Brasilia, Santa Rita, Augusto, J. Sahlberg (MNHN). Corporaal 1950: 98. Dos Santos and Filho 1982: 44.

Diagnosis. The round testaceous marking on the basal ½ of the elytral disc will distinguish the members of this species from congeners.

Redescription. Size. Length 11.0 mm; width 2.8 mm. Form. As in Fig. 84 . Color. Forebody, pterothorax, and legs dark castaneous; antenna testaceous; elytra bicolorous, disc mostly castaneous, large round testaceous marking in elytral basal ½, apical 1/3 testaceous; abdomen flavotestaceous. Head. Cranium finely punctate, frons about as wide as length of antennal pedicel; EW/FW 55/15. Thorax. Pronotum finely punctate, with 2 tumescences, narrowly concave at middle; PW/PL 120/165; elytra with asetiferous punctures concentrated in basal half near sutural margin, interstitial spaces very wide; EL/EW 480/85. Abdomen. Aedeagus, phallobasic lobes very short, contiguous; edge of phallic plates serrate; phallobasic apodeme slightly lengthened.

Variation. Size. Length 10.0–13.0 mm; width 2.2–3.5 mm. Other than body size, the available specimens are quite homogeneous.

Natural history. Specimens were collected in Brazil during June, November, and December, one at 960 m.

Distribution (for map see Fig. 69 ). In addition to the holotype, I examined 19 specimens from: Brazil: Estado do Rio de Janeiro, Rio de Janeiro,?-XI-?. collector not noted; Estado do Bahia,?- VI- 1972, 960 m, Moacir Alvarenga; Villa Victoria,?-?-1890, Ch. Pujol; Estado do Minas Gerais, Pedra Azul,?- XII-1970, F. M. Oliveira. Specimens are deposited in: AMNH, BMNH, CASC, CMNH, CUIC, FSCA, MCNZ, MNHN, WFBM, and WOPC.

Notes. The holotype was examined, but the description is based on a homotype specimen.
