Diagnosis

Males of P. fontanettiae resemble those of P. robsoni by having the internal branch with a torsion in anal view ( Fig. 69D ), but differing by the torsion starting only apically; mesal margin of the internal branch straight; with a distal projection present and directed horizontally ( Figs 69D , 222F).

Etymology

Patronym honoring the researcher Dr Carmen S. Fontanetti, for her important contributions to the study of Brazilian millipedes ( Iniesta & Ferreira 2014).

Descriptive notes

MEASUREMENTS. 65–69 body rings (1–2 apodous + telson). Males: body length 55–76 mm; maximum midbody diameter 2.5–3 mm. Females: body length 60–81 mm; maximum midbody diameter 3–4.2 mm.

COLOR. Body color blackish; head, collum, and antennae darker, legs brownish; prozonites greyish anteriorly; metazonites with a medial brown band and a posterior reddish band.

HEAD. Antennae long ( Fig. 163G ), 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 5 rows.

BODY RINGS. Collum with lateral lobes rounded, with ca 6 striae, slightly curved ectad ( Fig. 68A ). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae below ozopores. Anterior sterna in midbody rings subrectangular, without transverse striae ( Fig. 168C ).

FIRST LEG-PAIR OF MALES. Coxae (cx) short (less than half of remaining podomere lengths), subtriangular, with the base arched, densely setose ( Fig. 69A ); prefemoral process (prf) as wide as half of prefemur, subcylindrical, densely setose up to its median region ( Fig. 69B ); 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. 69C ); prefemur compressed dorsoventrally; remaining podomeres setose.

GONOPODS. Gonocoxa (gcx) elongated, almost twice as long as telopodite, with the base arched; antero-posteriorly flattened ( Fig. 69D–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 ( Fig. 69D ), arising just before ending of sh; solenomere (sl) with apicomesal process (amp) rounded; ectal process (ep) subtriangular, separated from amp by deep notch; sa located at mesal portion, visible apically. Internal branch (ib) subtriangular, narrow and with straight mesal edge, surrounding base of tp as a shield; with torsion of 180° in the distal portion, visible in anal view, and a rounded, elongated projection directed ectad; ib with setae along its entire margin exceeding apically seminal region of sl ( Fig. 69D–F ).

VULVAE. As typical for the genus. Bursa subtriangular, glabrous ( Fig. 177I ); internal valve subtriangular, with mesal region slightly rounded; operculum narrow, curved ectad; external valve wide, subtriangular.

Distribution

The species occurs in limestone caves from the south region of the Karst province of the Bambuí Limestone Group and forests in the Zona da Mata mesoregion in Minas Gerais State, Brazil ( Fig. 182 ).
