Phylogeny of Anisepyris Kieffer (Hymenoptera: Bethylidae: E pyrinae), with investigation of diagnostic features

Abstract A cladistic analysis based on 120 morphological characters and 72 OTUs was conducted for the flat wasp genus Anisepyris Kieffer. The is mainly Neotropical region with few Nearctic species. retrieved well-supported relationships among species exposed distribution of synapomorphies lineages, particularly concerning mandible shape, dorsal pronotal area sulcus, mesopleural foveae. main diagnostic characters, described by Barbosa Azevedo (2018) 13 species-groups , were scrutinized. Transformation series evolutionary hypotheses also discussed. This discussion elucidates importance each character in evolution diversification along different lineages. proposed, relation to their features. hypothesis about original subsequent diversifications In conclusion, due a possible recent origin species, dispersion could be related primarily dense forest areas; posterior distributions disparate areas from environment.
