| Sumario: | <i>Plumolepilius</i> Barrios-Izás & Anderson, 2016 is a leaf litter weevil genus that inhabits montane broadleaf forests from southern Mexico to northern Panama. The genus consists of 27 species, 22 distributed in the Chiapas Highlands province (Mexican Transition Zone) and 5 found in the Pacific dominion (Neotropical region) in Costa Rica and Panamá. Here, we analyze the phylogenetic relationships of the species of <i>Plumolepilius</i> based on 20 external body characters and 9 characters from the genitalia. The first dichotomy of the cladogram separates two species from the Pacific dominion from the remaining species of <i>Plumolepilius</i> from the Chiapas Highlands province and three species restricted to the Pacific dominion. We hypothesize that redundant distributions in the taxon-area cladogram of the genus may be due to dispersal events, probably during the Pleistocene glaciations. |
