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 ).
