The male and female genital morphology of the tribe Aphractini is presented in this study. Four species are included: Aphractus acuminatus, Paraphractus abbreviatus, Polycleptidella chilensis and Polycleptis scutellifera.
A dichotomous key to the genera is provided. The lengths between the
female spermathecal duct and titillatory articulated processes are
similar within species but differ between them. Therefore, we propose
that the function of these organs could be associated with the sperm
removal strategy.
Key words: Pseudophyllinae, Sexual selection, South America, Taxonomy.
