Diagnosis

Males of P. morettii sp. nov. resemble those of P. pusilla by having short coxae on the first leg-pair with constriction at about midlength ( Fig. 158A ), but differing by having mentum and stipes of gnathochilarium with long scattered setae ( Figs 174C , 197F, 199C); solenomere with seminal apophysis located medially ( Fig. 158D ).

Etymology

Species named after the beloved grandfather of the first author, Roberto Moretti (1933–2019). Noun in the genitive case.

Description

MEASUREMENTS. 55–58 body rings (1–2 apodous + telson). Males: body length 45.4–67.9 mm; maximum midbody diameter 2.8–3.8 mm. Females: body length 45.3–68 mm; maximum midbody diameter 2.8–5 mm.

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

HEAD. Antennae short ( Fig. 164A ), 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. Mentum and stipes of gnathochilarium with scattered long setae ( Figs 174C , 197F, 199C). Ommatidial cluster well-developed, elliptical; ca 35 ommatidia in 5 rows.

BODY RINGS. Collum with lateral lobes rounded, with ca 7 shallow striae, curved ectad posteriorly ( Fig. 157A ). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae up to ozopore in anterior body rings. Anterior sterna in midbody rings subrectangular, without transverse striae ( Fig. 174C ).

FIRST LEG-PAIR OF MALES. Coxae (cx) short (less than half of remaining podomere lengths), subtriangular, with the base strongly arched and constricted medially, sparsely setose ( Fig. 158A ); prefemoral process (prf) less than half of prefemur, subcylindrical, curved ectad, densely setose up to its median region ( Fig. 158B ); 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. 158C ); prefemur compressed dorsoventrally; remaining podomeres setose.

GONOPODS. Gonocoxa (gcx) longer than twice telopodite, with the base arched; antero-posteriorly strongly flattened ( Fig. 158D–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) large, rounded. Telopodite (tp) almost as wide as gcx ( Fig. 158D ); solenomere (sl) with short squamous region; apicomesal process (amp) elongated, subtriangular; ectal process absent; sa located at medial portion, not visible apically. Internal branch (ib) narrow and foliaceus; ib with setae along its entire margin, but only with the apical setae exceeding seminal region of sl ( Fig. 158D–F ).

VULVAE. As typical for the genus. Bursa subtriangular, glabrous ( Fig. 179G ); internal valve subtriangular, slightly rounded; operculum narrow; external valve subtriangular.

Distribution

Known only from the mountain range of Serra do Itapety, a partially preserved area with patches of Atlantic Forest in São Paulo State, Brazil ( Fig. 191 ).
