Differential diagnosis

Females differ from those of most species of Paratropis , except P. urku sp. nov. and P. salsa sp. nov., in the shorter spermathecae receptacles ( Fig. 2E ). From P. urku in the narrower basis of the receptacles and from P. salsa in the wider, umbrella-like and less sclerotized receptacle fundus. Additionally, it differs from P. urku in the absence of abdominal pattern ( Fig. 2C ). Differs from P. chami sp. nov., described based on a male, by the morphology of abdominal tubercles which are smaller.

Etymology

The specific epithet (genitive) is a patronym in honor of Aureliano Buendía, the main character of Cien Años de Soledad the famous novel of Gabriel García Márquez, born in Aracataca, Magdalena, the Department where the species was found.
