The
male and female genital morphologies of the tribe Aphractini are
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.
