Abstract

New species described: Coleoxestia pucacurensis sp. nov. and C. unap sp. nov. (Cerambycinae, Cerambycini, Sphallotrichina); and Abanycha contamanina sp. nov. (Lamiinae, Hemilophini). Notes on Coleoxestia spinipennis interiorana Fragoso, 1993 and Coleoxestia rubromaculata (Gounelle, 1909) are provided in the remarks on C. pucacurensis sp. nov. The holotype of Coleoxestia bimaculata Fuchs, 1955 is illustrated for the first time. The depository institution of the holotype of Coleoxestia spinifemorata Fragoso, 1993 is corrected. The number of specimens in the original description of Hamaederus bipartitus (Buquet, 1860) is corrected. The geographical distribution of the type series of Coleoxestia olivieri Fragoso, 1993 is corrected. A key to species of Abanycha Martins & Galileo, 1997 is provided. The male of Allocerus dilaticornis Gory, 1832 is illustrated for the first time; the number of antennomeres in males (12) and females (11) of Allocerus is formally reported as a sexual dimorphism in the genus; the inversion of the sex of the specimens of Tropidosoma Perty, 1832 (= Allocerus) in Di Iorio (2003) is reported; and the sex of the three specimens of the type series of Tropidosoma bicarinatum Monné & Monné, 1998 is confirmed to be female. The female of Parachorenta demezi Delahaye & Santos-Silva, 2016 is illustrated for the first time and the main differences from the male are reported. 38 new country records are reported in Cerambycidae. Distenia (Distenia) tavakiliani Santos-Silva & Hovore, 2007 (Disteniidae, Disteniinae) is reported from Peru for the first time.
