Diagnosis
Males of P. strinatii resemble those of P. ophiiulus and P. tocaiensis by having an internal branch shovel-shaped and with a horizontal plate (Fig. 130D), but differing by having the head and collum depigmented (Fig. 129A); solenomere with short ectal process, separated from the apicomesal process by a shallow notch (Fig. 130D–F).
Etymology
Patronym honoring the biospeleologist and collector of the type material Pierri Strinati (Mauriès 1974).

Descriptive notes
MEASUREMENTS. 68–72 body rings (1–2 apodous + telson). Males: body length 60–90 mm; maximum midbody diameter 3.1–4 mm. Females: body length 78–95 mm; maximum midbody diameter 3.5– 4.1 mm.
COLOR. Body color greyish; head, antennae, collum, and legs whitish; prozonites anteriorly darker; metazonites with a medial darker band and a posterior whitish.
HEAD. Antennae long (Fig. 164K), just reaching back to end of ring 6 when extended dorsally; antennomeres elongated; relative antennomere lengths 1<2<3>4>5≈6>7. Mandibular cardo with ventral margin swollen. Ommatidial cluster well-developed, elliptical; ca 23 ommatidia in 4 rows.
BODY RINGS. Collum with lateral lobes rounded, with ca 13 shallow striae, slightly curved ectad (Fig. 129A). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae up to ozopore in anterior body rings. Anterior sterna in midbody rings subrectangular, without transverse striae (Fig. 173A).
FIRST LEG-PAIR OF MALES. Coxae (cx) short (less than half of remaining podomere lengths), subtriangular, with the base arched and expanded, densely setose (Fig. 130A); prefemoral process (prf) as wide as half of prefemur, subcylindrical, densely setose along the entire ventral region (Fig. 130B); remaining podomeres with setae along the mesal region.
SECOND LEG-PAIR OF MALES. Coxa (cx) subrectangular; penis (pn) located at proximal region, rounded, not extended basally (Fig. 130C); prefemur compressed dorsoventrally; remaining podomeres setose.
GONOPODS. Gonocoxa (gcx) subtriangular, basally expanded and progressively less wide (Fig. 130D–F), with the base not arched; antero-posteriorly strongly flattened, longitudinal thickened ridge with rows of papillae mesally. Seminal groove (sg) curved; arising medially on mesal cavity and terminating apically on the seminal apophysis (sa). Shoulder absent. Telopodite (tp) almost as wide as gcx (Fig. 130D); solenomere (sl) with apicomesal process (amp) short, rounded; ectal process (ep) short, subtriangular, separating from amp by shallow notch; sa located at mesal portion, not visible apically. Internal branch (ib) shovel-shaped and rounded apically, with horizontal plate; setae restricted to the apical region of ib exceeding seminal region of sl (Fig. 130D–F).
VULVAE. As typical for the genus. Bursa subtriangular, glabrous (Fig. 179A); internal valve subtriangular; operculum expanded apically, curved ectad; external valve subtriangular, as wide as half of internal valve in oral view.
Distribution
Known only from the Karst region of Alto Ribeira on the border of the Brazilian states of São Paulo and Paraná (Fig. 188). Although no restriction of P. strinatii to caves or rocky outcrops may be assumed, the species has not ever been recorded free-living in the forests of the region.
Comments
The lectotype and the paralectotypes (one male, two females, and two immatures) from Areias Cave, Iporanga, deposited at the Muséum national d’histoire naturelle, Paris, France (MNHN), were not examined during this study. Nevertheless, topotypes from caves in Iporanga were examined (Fig. 188).
