Phylogeny, distribution, and description of a Caribbean species of <i>Dicepolia</i> (Lepidoptera: Crambidae).

Abstract

Dicepolia nigritinctalis sp. nov. is described from two female specimens from eastern Cuba and Chiapas, Mexico. The new species is most closely related to D. rufitinctalis (Hampson) or D. aerealis Hayden and occurs on the northern periphery of the range of the genus. Significant range extensions are reported for other species of Dicepolia Snellen across central and southern Brazil. A phylogenetic analysis of Dicepolia with 36 morphological characters, including two quantitative characters, indicates monophyly of the Malagasy and Neotropical groups and within the latter, monophyly of the small- and largebodied species groups.
