Axina diversesignata Pic, 1946

Figures 40 , 69 , 78 .

Axina diversesignata Pic, 1946: 15 . Lectotype. Gender not known. Here designated. Type locality: Brésil (MNHN). Corporaal 1950: 98. There is no indication regarding how many specimens were available to Pic when he made his description, therefore, I invoke Recommendation 73F of the ICZN (1999) and designate a lectotype for this nominal species.

Diagnosis. There are two somewhat spheroid, broadly connected, testaceous maculae in the center of the elytra. This characteristic will distinguish the members of this species from congeners.

Redescription. Size: Length 15.0 mm; width 4.0 mm. Form. As in Fig. 78 . Color. Forebody, antennae, pterothorax black; elytra bicolorous, mostly black, with 2 somewhat spheroid, broadly connected, testaceous maculae in center of disc, apical 1/5 testaceous; legs bicolorous, femora and tibiae black, tarsi brown; abdomen bicolorous, visible basal 3 sternites black, visible distal apical 3 sternites yellow. Head. Cranium finely punctate, frons about as wide as length of antennal pedicel; EW/FW 65/15. Thorax. Pronotum finely punctate, with 2 tumescences, concave at middle; PW/PL 150/205; elytra, asetiferous punctures striate, punctures extend slightly beyond elytron middle, width of interstitial spaces variable; EL/EW 600/130. Abdomen. Aedeagus ( Fig. 40 ), phallobasic lobes slightly curvate apically; phallic plates not serrate; phallobasic apodeme abbreviated.

Variation. Size. Length 10.5–15.0 mm; width 2.2–4.0 mm. The centrally located elytral maculae vary slightly in shape.

Natural history. Specimens were collected in Bolivia during November, December, and March, in Peru during May, and in Brazil during March and November.

Distribution (for map see Fig. 69 ). In addition to the lectotype, I examined 9 specimens from: Bolivia: Departamento de Santa Cruz, Potrerillos del Guenda, Snake Farm, 30-XI-3-XII-2012, Wappes & Skillman; 3.7 km SSE Buena Vista, Hotel Flora & Fauna, 5-15-XI-2001, tropical transition forest, M. C. Thomas & B. K. Dozier; Provincia Sara,?- III-1913, Steinbach. Peru: Provincia San Martin, Tarapoto,?- V-1886, M. de Mathan. Brazil: Estado do Pará, Jacareacanga,?- X-1969, F. R. Barbosa; Estado do Amazonas, Tarapoto,?-?-1885, M. de Mathan; Reserva Ducke, 26 km NE Manaus,?- III-1995, Malaise trap, Barbosa; Specimens are deposited in: ACMT, BMNH, CMNH, CUICIC, FMNH, FSCA, MNHN, and WOPC.
