A new Amazonian species of Dysmerus Casey (Coleoptera, Cucujoidea, Laemophloeidae) from Brazil

Bento, Matheus

Abstract This paper describes and illustrates a new Amazonian species of the lined flat bark beetle genus Dysmerus Casey, 1884. Dysmerus calicicornis sp. nov. is most similar to two species, D. curvicornis Thomas, 2009 and D. hamaticornis Thomas, 2009, sharing with them the male antennal scape apically flat, strongly deflected internally. The new species, however, can be easily distinguished from both by the male antennal scape caliciform in dorsal view, with a curved, tooth-like outer projection, and the presence of secondary sublateral lines on the pronotal surface. Additionally, the previous key to Dysmerus males is modified to include D. calicicornis sp. nov.
