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 ).
