Etymology. The specific epithet is non-Latin adjective (invariable) taken from Kichwa language meaning “large” referring to the large size of the species.

Diagnosis. Females of this species most resemble those of P. pukallucha sp. nov. and P. esmeraldas sp. nov., and are differentiated by their smaller carapace length, x 7.27, n =3, while x 9.30, n= 3 and 8.62 mm respectively in the latter, and from both species by their strongly constricted spermathecae (Fig. 13C–E); while slightly constricted (Fig. 8C–E) in P. pukallucha sp. nov. and, spermathecae are not constricted in P. esmeraldas sp. nov. (Fig. 2C). Males are distinguished from those of P. esmeraldas sp. nov. by their straight carapace margin (Fig. 14A), deeply notched in the latter (Fig. 4A), from both species by their subtegulum with notch and bent embolus tip (Fig. 15B, E); while the subtegulum is not notched and the embolus tip is curved in P. esmeraldas sp. nov. (Fig. 5D) and embolus with straight tip in P. pukallucha sp. nov. (Fig. 11B, E).
