The more slender antennomeres of the antennal capitulum (compare Figs. 158 and 166 ) conveniently distinguish the members of this species from those of Ichnea atra Opitz , new species . Also, unlike in I. atra , the members of this species have the pronotum densely vested with golden setae. Description. Size : Length 7.0 mm; width 2.8 mm . Form ( Fig. 144 ): Oblong subovoid. Integumental color ( Fig. 41 ): Cranium mostly black in upper frons, vertex, and upper epicranium, antennal apex yellow; pronotal integument mostly black, anterior angles yellow; elytra black. Head : HW/PW 1.0; frons indented; EW/VW 2.1; antennal funicle not compressed ( Fig. 158 ). Thorax : PL/PW 1.0; elytra subovoid, EL /PL 4.7; EL/EW 2.1; pronotum densely vested with golden setae; anterior margin of protibia with 11 spines. Male genitalia : Aedeagus as in Fig. 187 . Variation. Size: Length 4.5–7.7 mm ; width 1.7–2.5 mm . The extent of yellow at, and posterior to, the pronotal anterior angle varies. It extends to the posterior angle in two of the paratypes . Further- more, in some specimens there is a faint oblique fascia at the middle of the elytral disc. Variation. Specimens have been collected during October through December, and during February; one at 350 m elevation. Distribution. The species is known only from northwestern and central Brazil ( Map 2 ). Etymology. The specific epithet is a Latin compound name stemming from the noun acanthus (= corner) and the adjective melina (= honey-colored) and refers to the light coloration on the anterior angles of the pronotum.
