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 ).
