Diagnosis
Males of P. erikae resemble those of P. mesai, P. bucculenta sp. nov., and P. curvata sp. nov. by having a mesally curving telopodite (Fig. 67D), but differing by the presence of a large and hexagonal-shaped process on the first leg-pair (Fig. 67A).
Etymology
Patronym honoring the collector Dr Erika Taylor (Iniesta & Ferreira 2014).

Descriptive notes
MEASUREMENTS. 61 body rings (2 apodous + telson). Males: body length 52–55 mm; maximum midbody diameter 3–3.5 mm. Females: body length 50–55 mm; maximum midbody diameter 3.3–3.5 mm.
COLOR. Body color brownish grey; head, collum, and antennae darker grey; prozonites greyish anteriorly; metazonites with a lighter posterior band; legs brownish.
HEAD. Antennae long (Fig. 163F), 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 narrow. Ommatidial cluster well-developed, elliptical; ca 32 ommatidia in 5 rows.
BODY RINGS. Collum with lateral lobes broadly rounded, with ca 5 striae, strongly curved ectad (Fig. 66A). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae slightly above ozopore in anterior body rings. Anterior sterna in midbody rings subrectangular, without transverse striae (Fig. 168B).
FIRST LEG-PAIR OF MALES. Coxae (cx) elongated (as long as the sum of remaining podomere lengths), subtriangular, with the base arched, densely setose (Fig. 67A); prefemoral process (prf) large, curved mesad, and projected laterally, densely setose along its entire extension (Fig. 67B); remaining podomeres with setae along the mesal region.
SECOND LEG-PAIR OF MALES. Coxa (cx) rounded; penis (pn) located at proximal region, rounded, not extended basally (Fig. 67C); prefemur slightly compressed dorsoventrally; remaining podomeres setose, with long setae mesally.
GONOPODS. Gonocoxa (gcx) elongated, but less than twice the length of telopodite, with the base slightly arched; flattened antero-posteriorly (Fig. 67D–F); with rows of papillae mesally. Seminal groove (sg) curved; running mesally and terminating apically on the seminal apophysis (sa). Shoulder (sh) rounded. Telopodite (tp) almost as wide as gcx (Fig. 67D), strongly curved mesad; solenomere (sl) with apicomesal process (amp) subtriangular; ectal process absent; sa located at mesal portion, slightly visible apically. Internal branch (ib) shovel-shaped, narrow; ib with setae along its entire margin slightly exceeding apically seminal region of sl (Fig. 67D–F).
VULVAE. As typical for the genus. Bursa subtriangular, glabrous (Fig. 177H); internal valve subtriangular, with mesal region rounded; operculum narrow, curved ectad; external valve wide, subtriangular.
Distribution
The species occurs in limestone caves and surrounding forests from the south region of the Karst province of the Bambuí Group, Minas Gerais State, Brazil (Fig. 182).
