Calycibidion rubricolle Galileo and Martins , new species

( Figure 3 )

Description. Head black. Frons smooth with depressed areas in front of the antennal tubercles; longitudinal corrugations between the tubercles. Vertex sparsely punctate. Upper ocular lobes with three rows of ommatidia. Antennae black surpassing the elytral apices in the middle of antennomere IX. Scape microsculptured with sparse punctures.

Prothorax reddish. Pronotum with a brownish band along the anterior margin; punctures sparse. Prothorax and prosternum sides punctate. Mesosternum and metasternum reddish. Mesepisterna, mesepimera, metepisterna and a narrow band on the sides of the metasternum microsculptured. Metasternum central region punctate with long, sparse hairs.

Elytra ( Figure 3 ) reddish-orange until slightly after the middle and black in the remaining portion. Coarsely, deeply and densely punctate throughout the entire surface, with erect and long hairs, organized in rows. Elytral apices emarginated; marginal spine longer and sharper than the sutural one.

Legs black, except coxae and base of femur, which are reddish; apical tarsomeres reddish-brown. Femurs with sparse punctures. Tibiae hairy and carinated.

Urosternites black, except at the basal half of I, which is reddish-brown; sparsely punctate with long hairs.

Measurements in mm. Total length, 7.9-8.6; prothorax length, 1.8-1.9; largest prothoracic width, 1.2- 1.3; elytra length, 5.0-5.7; humeral width, 1.7-1.8.

Type material. Male holotype, BRAZIL, Bahia: São Félix do Coribe-Coribe , (km 24, 13 o 33’S 4415’W, 493 m), 07.XII.2007, A. M. Silva-Neto col. ( UEFS) ; male paratype, same data of the holotype, F. Bravo col. ( MZSP) .

Etymology. Latin, rubrus = red; collum = neck; allusion to the red prothorax.

Diagnosis. Calycibidion rubricolle sp. nov. is similar to C. turbidum Napp and Martins, 1985 concerning the elytral apices with two spines. It is distinguished by its black head and reddish pronotum; black antennae; black legs with coxae and femur bases reddish. The head and prothorax of C. turbidum are black; the pedicels, the flagellomeres and the legs are brownish.
