Other material examined. ECUADOR: Esmeraldas: Monterrey (–00.039292° –79.492039°) 196 m, 1 ♂, 19. Mar. 2016, E. Tapia, ECFN 863 (ZMH-A0003005).
Etymology. The specific epithet is a non-Latin combination of adjectives (invariable) taken from Kichwa language “puka” + “llucha” meaning “red coloration and bare” referring to the reddish coloration of the species, and body bearing few setae and soil particles.
Diagnosis. Females and males most resemble those of P. kapak sp. nov. and P. esmeraldas sp. nov. but females are differentiated those of from both species by their longer carapace (x 9.30, n = 3) versus (8.62) in P. esmeraldas sp. nov. and (x 7.27, n = 3) in P. kapak sp. nov. Furthermore, female spermathecae heads are slightly constricted (Fig. 8C–E) while, in P. esmeraldas sp. nov., the spermathecae heads are not constricted (Fig. 2C) and, in P. kapak sp. nov., the spermathecae are strongly constricted (Fig. 13C–E). Males are distinguished by their longer carapace, x 7.80, n = 3, versus 5.59 in P. esmeraldas sp. nov. and x 6.88, n = 3 in P. kapak sp. nov. Furthermore, males are distinguished from those of P. esmeraldas sp. nov. by their straight carapace margin (Fig. 10A), deeply notched in the latter (Fig. 4A), and straight embolus tip (Fig. 11B, E) smoothly curving in the latter (Fig. 5D); from P. kapak sp. nov. by their straight embolus tip (Fig. 11B, E) bent in the latter (Fig. 15B, E).
