Diagnosis

Males of P. paulista slightly resemble those of P. aurea sp. nov. by having a solenomere with a spiniform ectal process deeply notched separating it from the apicomesal process ( Fig. 110D ), but differing by an internal branch shovel-shaped with horizontal plate ( Fig. 110D–F ).

Etymology

Although unspecified, the name is evidently related to the demonym “paulista”, in reference to the inhabitants of the Brazilian state of São Paulo, where the species occurs.

Descriptive notes

MEASUREMENTS. 55–71 body rings (1–2 apodous + telson). Males: body length 67.9–79.4 mm; maximum midbody diameter 3.2–3.6 mm. Females: body length 76.4–87 mm; maximum midbody diameter 4.1– 4.9 mm.

COLOR. Body color brownish yellow; head, collum, and antennae darker; prozonites and metazonites anteriorly darker, with a posterior band lighter; legs brownish.

HEAD. Antennae short ( Fig. 164G ), 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 swollen. Ommatidial cluster well-developed, elliptical; ca 40 ommatidia in 5 rows.

BODY RINGS. Collum with lateral lobes broadly rounded, with ca 6 striae ( Fig. 109A ). 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. 171D ).

FIRST LEG-PAIR OF MALES. Coxae (cx) elongated (as long as the sum of remaining podomere lengths), subtriangular, with the base slightly arched and expanded, densely setose ( Fig. 110A ); prefemoral process (prf) as wide as half of prefemur, subcylindrical, densely setose along in its entire extension ( Fig. 110B ); remaining podomeres with setae along the mesal region.

SECOND LEG-PAIR OF MALES. Coxa (cx) large and subrectangular; penis (pn) located at proximal region, rounded, not extended basally ( Fig. 110C ); prefemur compressed dorsoventrally; remaining podomeres setose.

GONOPODS. Gonocoxa (gcx) elongated, almost twice as long as telopodite, with the base arched; antero-posteriorly flattened ( Figs 110D–F , 212D, 213B); with rows of papillae mesally. Seminal groove (sg) curved; arising medially on mesal cavity and terminating apically on the seminal apophysis (sa). Shoulder absent. Telopodite (tp) almost as wide as gcx ( Figs 110D , 218E); solenomere (sl) with apicomesal process (amp) subtriangular; ectal process (ep) spiniform, elongated, separating from amp by deep notch; sa located at mesal portion, curved mesad, elongated. Internal branch (ib) shovel-shaped, with horizontal plate; long setae restricted to the apical region of ib exceeding seminal region of sl ( Figs 110D–F , 213B).

VULVAE. As typical for the genus. Bursa subtriangular, glabrous ( Fig. 178I ); internal valve subtriangular, with mesal region rounded; operculum narrow, S-shaped; external valve wide, subtriangular.

Distribution

Known from the central-west region of São Paulo State, Brazil ( Fig. 186 ); occurring in the Cerrado biome (tropical savanna ecoregion) and in second-growth forests in the region.

Comments

The lectotype from Cerqueira César and the paralectotypes (two females) from Batista Botelho, deposited at the Muséum national d’histoire naturelle, Paris, France (MNHN), were not examined during this study.
