Etymology. The specific name is a noun in apposition taken from the type locality, Pristirana Natural Reserve, a low evergreen protected forest in the Chocó region of Ecuador.

Diagnosis. Adult males and females are distinguished from sympatric species P. elicioi by their less cryptic body ( Figs 27, 28 ). Furthermore, males are distinguished by their less constricted bulb ( Figs 39–41 ), much more constricted in P. elicioi ( Figs 7–9 ). Females are distinguished from P. elicioi and P. florezi by the presence of longitudinal fold on the spermathecae ( Fig. 12 ); absent in two other species ( Fig. 10 ; Perafán et al., 2019, fig. 3D); from P. otonga sp. n. by the presence of multi-layered thin seta ( Fig. 28 ) and their longer spermathecae not acuminate apically ( Fig. 12 ), shorter and acuminate in P. otonga sp. n. ( Fig. 11 ) and multi-layered thin seta absent ( Figs 13 , 14 ).

Paired and ITC as in male; palpal claw without teeth. Genitalia: Internal genitalia with elongated spermathecae (4x longer than wide) straight, with longitudinal fold, not acuminate apically, with few loose lobed vesicles ( Fig. 12 ).

Variation of trichobothrial pattern (male paratype): tibiae I–IV (7/7/7/6); metatarsi I–IV (4/4/4/4); tarsi (8/7/7/8) ( Figs 42-49 ); palpal tibia (7): palpal tarsus (6) ( Fig. 35 ).
