Diagnosis

Males of P. maritima resemble those of P. halophila , P. sebastianus Brölemann, 1902 , P. patagonica Brölemann, 1902 , and P. insularis sp. nov. by having large and subrectangular coxae on the first leg-pair ( Figs 30E , 90A , 91B ) and suboval penis ( Figs 90C , 91E–F ), but differing by having the internal branch rounded; horizontal plate large, apically swollen when viewed anally ( Figs 32B , 35C , 90D ).

Etymology

Adjective referring to the geographical distribution of the species, occurring in islands of the Brazilian state of São Paulo ( Schubart 1949).

Descriptive notes

MEASUREMENTS. 70–81 body rings (1–2 apodous + telson). Males: body length 70–102 mm; maximum midbody diameter 3.7–5.9 mm. Females: body length 60–80 mm; maximum midbody diameter 3.8– 4.8 mm.

COLOR. Body color greyish; head and collum darker; prozonites greyish anteriorly; metazonites with a dark medial band and a light posterior band; antennae and legs light brown.

HEAD. Antennae short ( Fig. 163M ), 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 rounded, with ca 8 thickened striae, curved ectad anteriorly ( Fig. 89A ). Very faint constriction between prozonites and metazonites; prozonites smooth; metazonites laterally with transverse striae below ozopores. Anterior sterna in midbody rings subrectangular, with shallow transverse striae ( Fig. 170C ).

FIRST LEG-PAIR OF MALES. Coxae (cx) elongated (as long as the sum of remaining podomere lengths), subrectangular, with the base arched, densely setose ( Figs 30E , 90A , 91B ); prefemoral process (prf) as wide as half of prefemur, subcylindrical, densely setose along the entire ventral region ( Fig. 90B ); remaining podomeres with setae along the mesal region.

SECOND LEG-PAIR OF MALES. Coxa (cx) elongated and subrectangular; penis (pn) located at proximal region, rounded, slightly extended basally ( Fig. 90C , 91E–F ); prefemur dorsoventrally compressed; remaining podomeres setose.

GONOPODS. Gonocoxa (gcx) elongated, almost twice as long as telopodite, with the base slightly arched; flattened antero-posteriorly ( Fig. 91C , 90D–F ); with rows of papillae mesally. Seminal groove (sg) curved; protruded on squamous region of sl, arising medially on mesal cavity and terminating apically on the seminal apophysis (sa). Shoulder (sh) inconspicuous. Telopodite (tp) less than half as wide as gcx ( Figs 32B , 35C–D , 91D , 90D ); solenomere (sl) with apicomesal process (amp) subtriangular; ectal process absent; sa located at mesal portion, thickened apically. Internal branch (ib) shovel-shaped and rounded apically, with horizontal plate; setae restricted to the apical region of ib not exceeding seminal region of sl ( Fig. 91C , 90D–F ).

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

Distribution

The species is widely distributed in the Atlantic Forest of the Brazilian archipelago Alcatrazes and in the coastal region of São Paulo State, Brazil ( Fig. 184 ).
