Evolutionary relationships among tropical nectar-feeding bats

(Glossophaginae: Lonchophyllinae), based on morphological characters

Woodman N

Nectar-feeding bats serve an essential role in lowland tropical rain forests, acting as pollinators

for plants, seed dispersers, and predators on insects. Knowledge of the diversity of this group

and its evolution is necessary to understanding the development of the ecological relationships

of these bats and the species with which they typically interact. The discovery of two new

species of lonchophylline nectar-feeders in Colombia and Peru prompted me to undertake a

study of the phylogenetic relationships in this branch of the group. I completed a series of

analyses of a matrix of 177 characters with the computer program PAUP. These analyses

used a variety of outgroup taxa that reflect the diversity of opinions regarding the closest

relatives of the Lonchophyllini. Results support the contention that lonchophyllines represent a

distinct group of nectar-feeders. However, relationships within this group remain poorly

resolved. Characteristics that define individual species in this group show complex patterns of

evolution that suggest convergence in a number of characters as a result of common feeding
