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 View Fig , 90A View Fig , 91B View Fig ) and suboval penis ( Figs 90C View Fig , 91E–F View Fig ), but differing by having the internal branch rounded; horizontal plate large, apically swollen when viewed anally ( Figs 32B View Fig , 35C View Fig , 90D View Fig ).

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 View Fig ), 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 View Fig ). 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 View Fig ).

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 View Fig , 90A View Fig , 91B View Fig ); prefemoral process ( prf) as wide as half of prefemur, subcylindrical, densely setose along the entire ventral region ( Fig. 90B View Fig ); 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 View Fig , 91E–F View Fig ); 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 View Fig , 90D–F View Fig ); 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 View Fig , 35C–D View Fig , 91D View Fig , 90D View Fig ); 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 View Fig , 90D–F View Fig ).

VULVAE. As typical for the genus. Bursa subtriangular, glabrous ( Fig. 178B View Fig ); 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 View Fig ).
