Diagnosis
Males of P. urbica differ from all congeners by having the telopodite and internal branch short (less than ⅓ of gonocoxa in length) (Fig. 141D–F); solenomere short and trianguliform; apicomesal process located medially (Figs 141D, 223B).
Etymology
Although unspecified, the name is evidently related to the Latin adjective ‘ urbicus ’ (feminine ‘ urbica ’) = ‘related to city’, referring to the occurrence of the species in urban areas.

Descriptive notes
MEASUREMENTS. 50–53 body rings (1–2 apodous + telson). Males: body length 47.6–50.2 mm; maximum midbody diameter 2.5–2.7 mm. Females: body length 52–53 mm; maximum midbody diameter 2.8–3 mm.
COLOR. Body color brownish grey; head, collum, antennae darker; prozonites anteriorly greyish; metazonites with a posterior band lighter; legs brownish.
HEAD. Antennae short (Fig. 164O), 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 41 ommatidia in 6 rows.
BODY RINGS. Collum with lateral lobes rounded, with ca 9 striae, slightly curved ectad (Fig. 140A). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae below ozopore. Anterior sterna in midbody rings subrectangular, without transverse striae (Fig. 173E).
FIRST LEG-PAIR OF MALES. Coxae (cx) short (less than half of remaining podomere lengths), subtriangular, with the base arched, densely setose (Fig. 141A); prefemoral process (prf) about as wide as half of prefemur, subcylindrical, curved ectad, densely setose up to its median region (Fig. 141B); 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. 141C); prefemur compressed dorsoventrally; remaining podomeres setose.
GONOPODS. Gonocoxa (gcx) rounded, with the base arched; antero-posteriorly flattened (Fig. 141D– 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) rounded. Telopodite (tp) shorter than ⅓ of gcx (Fig. 141D); solenomere (sl) with short squamous region; apicomesal process (amp) subtriangular, located medially, with sa also at medial portion and visible apically; ectal process absent. Internal branch (ib) short, subtriangular, surrounding basally tp as a shield; ib with setae along its entire margin, but only with the apical setae exceeding seminal region of sl (Figs 141D–F, 223B).
VULVAE. As typical for the genus. Bursa subtriangular, glabrous; internal valve subtriangular; operculum large, curved ectad; external valve wide, subtriangular.
Distribution
The species has been recorded only in the metropolitan region of the Brazilian city of São Paulo and surrounding area (Fig. 189).
