Diagnosis
Males of P. rolamossa differ from those of all other species of the genus by having a solenomere with a subtriangular and elongated ectal process exceeding in length the rounded apicomesal process (Fig. 118D).
Etymology
Noun in apposition, taken from the State Park “Parque Estadual do Rola Moça” where the species was found (Iniesta & Ferreira 2013c).

Descriptive notes
MEASUREMENTS. 60–62 body rings (1–2 apodous + telson). Males: body length 56 mm; maximum midbody diameter 4 mm. Females: body length 58 mm; maximum midbody diameter 4.1 mm.
COLOR. Body color brownish grey; head, antennae, collum, and legs darker; prozonites anteriorly greyish; metazonites with a medial darker band and a posterior lighter one.
HEAD. Antennae long (Fig. 164I), 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 38 ommatidia in 6 rows.
BODY RINGS. Collum with lateral lobes rounded, with ca 10 striae, strongly curved ectad (Fig. 117A). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae above ozopore in anterior body rings. Anterior sterna in midbody rings subrectangular, without transverse striae (Fig. 172A).
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. 118A); prefemoral process (prf) about as wide as half of prefemur, subcylindrical, densely setose up to its median region (Fig. 118B); 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. 118C); prefemur compressed dorsoventrally; remaining podomeres setose.
GONOPODS. Gonocoxa (gcx) elongated, twice longer than telopodite, with the base slightly arched; antero-posteriorly flattened (Fig. 118D–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) long, subtriangular. Telopodite (tp) almost as wide as gcx (Figs 118D, 217C, 219B); solenomere (sl) with apicomesal process (amp) short, rounded; ectal process (ep) subtriangular, elongated, exceeding in length the amp; sa located at mesal portion, nearly not visible apically. Internal branch (ib) subtriangular, narrow, surrounding basally tp as a shield; with torsion of 180° in the distal portion but without projection; ib with setae along its entire margin slightly exceeding apically seminal region of sl (Fig. 118D–F).
VULVAE. As typical for the genus. Bursa subtriangular, glabrous (Fig. 178K); internal valve subtriangular; operculum narrow; external valve wide, subtriangular.
Distribution
The species is widely distributed in iron ore caves and surrounding forests in the central region of Minas Gerais State, Brazil (Fig. 187).
