Differential diagnosis

Differs from most species of the genus, excepting P. urku sp. nov. and P. aurelianoi sp. nov., in the shorter spermathecae receptacles ( Fig. 9E ). From P. urku in the narrower, slightly longer and more divergent spermathecae receptacles and from P. aurelianoi by the different dorsal abdominal pattern ( Fig. 9C ), absence of bacilliform setae on the abdomen and slightly longer spermathecae receptacles. Differs from P. chami sp. nov., described based on a male, by the morphology of abdominal tubercles which are smaller and without bacilliform setae.

Etymology

The specific epithet is a noun in apposition, referring to a popular music and dance form from South and Central America. Salsa is a very popular dance in Cali, the capital of Valle del Cauca, the Department where the species was found.
