Acentroptera rubronotata Pic incertae sedis

Acentroptera rubronotata Pic 1932: 15 (type: Brazil, Tapera, depository unknown). Carvalho and Carvalho 1939: 54 (faunal list); Papp 1953: 51 (catalog); Uhmann 1957: 66 (catalog), 1964a: 412 (catalog); Descarpentries and Villiers 1959: 144 (types).

Description. Translation of Pic (1932): Somewhat elongate, shining, testaceous; elytra with 3 maculae anteriorly and posteriorly; elytra red-green and marked with black; pronotum red and green, trivittate, strongly and densely punctuate. Total length 8-10 mm.

Very similar to A. maculata but differs by the reduced red maculae and dark purple marking on the elytra and with the costae less produced.

Discussion. The type of this species could not be located in the M. Pic collection in the MNHN (A. Mantilleri, per. com.). I have been unable to locate determined specimens of this species or any specimens fitting this description and the original description is too superficial to determine the placement of the species. Until the type is located, the species should be treated as incertae sedis (ICZN 1999, Art. 67.2.5).

Host plant. Unknown.

Distribution. Brazil (Pará).
