Axina lobispinula Opitz , new species

Figures 24 , 69 , 79 .

Type material. Holotype. Male. Type locality: Brazil: Bahia, Encruzilhada ,?- XI- 1974, 960 m, M. Alvarenga ( FSCA) . Paratypes. 4 specimens. Brazil: Estado do Minas Gerais, Pedra Azul ,?- XI-1971, F. M. Oliveira ( MCNZ, 1; WOPC, 1) ; idem,?- XII-1970, F. M. Oliveira ( CASC, 1: WFBM, 1) .

Diagnosis. In the members of this species, the elytral basal castaneous marking traverses the entire basal margin. This characteristic will distinguish the members of this species from superficially similar specimens of A. orcastomata , in which the castaneous marking in question is restricted to the humeral angle.

Description. Size. Length 9.0 mm; width 2.0 mm. Form. As in Fig. 79 . Color. Cranium castaneous; antenna testaceous; prothorax bicolorous, venter and pronotal sides dark castaneous, pronotum middle light castaneous; mesothorax and metathorax dark castaneous; elytra bicolorous, mostly testaceous, epipleural margin brown, brown region extends medially along basal margin, at middle, and posteriorly in area before apex, posterior brown making narrowly extends anteriorly and posteriorly along sutural margin; legs mostly castaneous, basal area of femora and tarsi testaceous; abdomen testaceous. Head. Cranium finely punctate, frons slightly wider than length of antennal pedicel; EW/FW 40/20. Thorax. Pronotum finely punctate, with 2 tumescences, concave at middle; PW/PL 105/130; elytra, asetiferous punctures subseriate, punctures extend slightly beyond elytral ½, width of interstitial spaces variable; EL/EW 380/80. Abdomen. Aedeagus ( Fig. 24 ), phallobasic lobes with preapical spine; edges of phallic plates serrate near phallic apex; phallobasic apodeme abbreviated.

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

Distribution (for map see Fig. 69 ). This species is known from Brazil.

Etymology. The specific epithet, lobispinula , is a Latin compound name that stems from lobi (= lobed) and spinula (= spine). I refer to the spine near the apex of the phallobasic lobes.
