Abstract
AbstractPterocallini is one of the largest tribes within Ulidiidae, with more than 130 species described in 27 genera. The great majority of Pterocallini species are endemic to the Neotropics. They are characterised by the wings pictured with dark patterns, but some species of Pterocallini also are recognised by some extraordinary forms of sexual dimorphism, such as stalked eyes. In this study, we propose the first hypothesis of internal relationship of the tribe and tested the monophyly of some of the genera of Pterocallini. Our matrix consisted of 86 morphological characters and 58 terminal taxa that were sampled from 21 genera of Pterocallini and four outgroup genera. We performed a parsimony analysis under implied weighting of the characters, which resulted in one maximum parsimonious tree. Our findings corroborate some of the preceding non‐phylogenetic hypotheses of sister relationships within Pterocallini. Our analysis supported the monophyly of the genera Aciuroides, Lathrostigma, Neoacanthoneura, Neomyennis, Plagiocephalus, Pseudopterocalla, Rhyparella, Terpnomyia and Xanthacrona but did not support natural groupings of Apterocerina, Dasymetopa, Megalaemyia, Paragorgopis, Pterocalla and Pterocerina species.
