Type material. Holotype. Female. Type locality: Serra da Bernada (Pernambuco), Duhant, 5.6.1894 (Brazil) ( MNHN) . Paratypes. 5 specimens. Brazil: Estado do Pernambuco, no other information available ( WOPC, 1) ; Serra da Bernada, 5-VI-1894, Duhant ( MNHN, 1) ; Estado do Bahia, S. Antonio da Barra, 11-XII-1888, Gounelle ( MNHN, 2) ; Estado do Ceará, Ceará, collection date and collector not noted ( WOPC, 1) .

Diagnosis. The asetiferous punctures are profusely distributed on the elytral disc; they reach the elytral apex. These characteristics will distinguish the members of this species from specimens of other Axina species with a partial black pronotal midline; this midline reaches the pronotal anterior margin in specimens of Axina polycaula .

Description. Size. Length 10.0 mm; width 2.5 mm. Form. As in Fig. 106 View Figures 106–109 . Color. Cranium and thoracic venter black; frons, epicranium, and legs castaneous; antenna testaceous; pronotal dorsum mostly castaneous, with narrow black line that extends from mesoscutellum to pronotal anterior margin; elytra bicolorous, mostly testaceous, castaneous markings at elytron middle and before elytral apex. Head. Cranium finely punctate, frons about as wide as length of antennal pedicel; EW/FW 45/15. Thorax. Pronotum finely punctate, with 2 paralateral spheroid tumescences, disc narrowly concave near middle; PW/PL 110/120; elytra, asetiferous punctures not striate, punctures extend posteriorly to elytral apex, width of interstitial spaces variable; EL/EW 460/85. Abdomen. Female pygidium trilobed distally ( Fig. 63 View Figures 62–63 , 66 View Figures 66–67 ); aedeagus ( Fig. 33 View Figures 33–36 ).

Distribution (for map see Fig. 71 View Figure 71 ). This species is known from Brazil.

Etymology. The specific epithet, polycaula , is a compound name that stems from the Greek poly (= many) and the Latin caula (= hole). I refer to the copious number of asetiferous punctures on the elytral disc.
