ETYMOLOGY: The specific name is a noun in apposition taken from the type locality. DIAGNOSIS: Males resemble those of the sympatric species P. zamora but have a shorter, ventrally expanded, distally widened embolus (figs. 424–427) and lack the cheliceral spines (fig. 421). This male is both too small and geographically too remote to be a likely match for any of the three species from Ecuador known only from females ( P. hermani , P. yasuni , and P. sucumbios ). MALE (PBI_OON 577, figs. 420–427): Total length 1.58. Elevated portion of pars cephalica appears reticulate. Chilum long, narrow, triangular. Anterior ledge of paturon with long, rectangular, medially directed process abutting chilum. Endites with ventral process much wider than dorsal process. Leg spination: femur I p0-0-1; tibiae: I v4-4-0, II v4-2-0; metatarsi I, II v2-2-0. Palps symmetrical; embolus relatively short, wide, prolaterally excavated. FEMALE: Unknown. OTHER MATERIAL EXAMINED: One male (with missing abdomen) taken with the type (QCAZ). DISTRIBUTION: Ecuador ( Zamora-Chinchipe ).
