Diagnosis

Males of P. tocaiensis resemble those of P. ophiiulus , P. strinatii , and P. sulcatula by having an internal branch shovel-shaped (see Figs 130D View Fig , 133D View Fig ), but differing by having the first leg-pair with subrectangular coxae, prefemoral process larger than half of prefemur ( Fig. 133B View Fig ); solenomere with rounded ectal process ( Fig. 133D–F View Fig ).

Etymology

Although unspecified, the name is evidently an adjective referring to the locality where the type material was found, Toca Cave.

Descriptive notes

MEASUREMENTS. 60 body rings (1 apodous + telson). Males: body length ca 50 mm; maximum midbody diameter 2 mm.

COLOR. Body color faded, but apparently uniform pale brownish; metazonites with a posterior band brown; head, collum, antennae, and legs brownish.

HEAD. Antennae short, 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 28 ommatidia in 5 rows.

BODY RINGS. Collum with lateral lobes rounded, with ca 9 shallow striae ( Fig. 132A View Fig ). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae from ca ⅓ length below ozopore. Anterior sterna in midbody rings subrectangular, without transverse striae ( Fig. 173B View Fig ).

FIRST LEG-PAIR OF MALES. Coxae ( cx) short (less than half of remaining podomere lengths), subrectangular, with the base arched and expanded, densely setose ( Fig. 133A View Fig ); prefemoral process ( prf) as wide as half of prefemur, subcylindrical, densely setose along the entire ventral region ( Fig. 133B View Fig ); remaining podomeres with setae along the mesal region.

SECOND LEG-PAIR OF MALES. Coxa ( cx) subrectangular; penis ( pn) located at proximal region, rounded, not extended basally ( Fig. 133C View Fig ); prefemur compressed dorsoventrally; remaining podomeres setose.

GONOPODS. Gonocoxa ( gcx) subtriangular, basally expanded and progressively less wide, with the base arched; antero-posteriorly flattened; with rows of papillae mesally ( Fig. 133D–F View Fig ). Seminal groove ( sg) straight up to ending of gcx, arising medially on mesal cavity, curved ectad in tp and terminating apically on the seminal apophysis ( sa). Shoulder absent. Telopodite ( tp) almost as wide as gcx ( Fig. 133D View Fig ); solenomere ( sl) with apicomesal process ( amp) short, slightly subtriangular; ectal process ( ep) short, rounded, separating from amp by shallow notch; sa located at mesal portion, not visible apically. Internal branch ( ib) shovel-shaped and rounded apically, with horizontal plate; setae restricted to the apical region of ib exceeding seminal region of sl ( Fig. 133D–F View Fig ).

VULVAE. As typical for the genus. Bursa subtriangular, glabrous ( Fig. 179B View Fig ); internal valve subtriangular; operculum narrow, curved ectad; external valve wide, subtriangular.
