Diagnosis
Males of P. leopoldoi resemble those of P. imbirensis and P. microzoporus by having a solenomere with the ectal process deeply notched separating it from the apicomesal process (Fig. 77D), but differing of P. imbirensis by having the head light brown, collum, antennae, and legs darker brown (Fig. 76), and of P. microzoporus by having the internal branch not curved ectad (Fig. 77D–F).
Etymology
Patronym honoring the Brazilian biospeleologist Dr Leopoldo Bernardi (Iniesta & Ferreira 2014).

Descriptive notes
MEASUREMENTS. 61–64 body rings (1–2 apodous + telson). Males: body length 50–52 mm; maximum midbody diameter 2.8–3 mm. Females: body length 55 mm; maximum midbody diameter 3.3 mm.
COLOR. Body color brownish; head light brown; collum, antennae, and legs darker brown; prozonites and metazonites dark brownish anteriorly, with a lighter posterior band.
HEAD. Antennae short (Fig. 163J), just reaching back to end of ring 5 when extended dorsally; relative antennomere lengths 1<2<3>4≈5<6>7. Mandibular cardo with ventral margin narrow. Ommatidial cluster well-developed, elliptical; ca 30 ommatidia in 5 rows.
BODY RINGS. Collum with lateral lobes rounded, with ca 9 shallow striae, slightly curved ectad (Fig. 76A). Very faint constriction between prozonites and metazonites; prozonites smooth; metazonites laterally with transverse striae below ozopore. Anterior sterna in midbody rings subrectangular, without transverse striae (Fig. 169C).
FIRST LEG-PAIR OF MALES. Coxae (cx) short (less than half of remaining podomere lengths), subtriangular, with the base arched, densely setose (Fig. 77A); prefemoral process (prf) as wide as half of prefemur, subcylindrical, densely setose up to its median region (Fig. 77B); remaining podomeres with setae along the mesal region.
SECOND LEG-PAIR OF MALES. Coxa (cx) large and rounded; penis (pn) located at proximal region, rounded, not extended basally (Fig. 77C); prefemur compressed dorsoventrally; remaining podomeres setose.
GONOPODS. Gonocoxa (gcx) elongated, almost twice as long as telopodite, with the base arched; antero-posteriorly flattened (Fig. 77D–F); with rows of papillae mesally. Seminal groove (sg) curved; arising medially on mesal cavity and terminating apically on the seminal apophysis (sa). Shoulder (sh) rounded. Telopodite (tp) almost as wide as gcx, with well-demarcated separation in relation to sh (Fig. 77D); solenomere (sl) with apicomesal process (amp) slightly subtriangular; ectal process (ep) short, subtriangular, separating from amp by deep notch; sa located at mesal portion, slightly visible apically. Internal branch (ib) subtriangular, narrow, surrounding base of tp as a shield; with torsion of 180° in the distal portion but without projection; setae starting at midlength of ib not exceeding seminal region of sl (Fig. 77D–F).
VULVAE. As typical for the genus. Bursa subtriangular, glabrous; internal valve subtriangular, with mesal region rounded; operculum narrow; external valve wide, subtriangular.
Distribution
The species occurs in limestone caves and surrounding forests from the Bambuí Group in the northern and central region of Minas Gerais State, Brazil (Fig. 183).
