Diagnosis

Males of P. anapophysis resemble those of P. bovei, P. caulleryi, P. inops, and P. xavieri Iniesta & Ferreira, 2014 by having solenomere with subtriangular ectal process directed horizontally (Fig. 49D), but can be easily distinguished by the absence of a prefemoral process on the first leg-pair (Fig. 49A–B).

Etymology

Named after the Greek prefix ‘ an -’ = ‘without’, and ‘ apophysis ’. Unspecified in the original description, but likely to be related to the absence of a prefemoral process on the first leg-pair.

Descriptive notes

MEASUREMENTS. 60 body rings (1–2 apodous + telson). Males: body length 90 mm; maximum midbody diameter 5 mm.

COLOR. Body color greyish; collum darker; metazonites with a light posterior band; antennae and legs brownish.

HEAD. Antennae long (Fig. 163B), just reaching back to end of ring 6 when extended dorsally; antennomeres elongated; relative antennomere lengths 1<2<3≈4<5≈6>7. Mandibular cardo with ventral margin swollen. Ommatidial cluster well-developed, elliptical; ca 23 ommatidia in 4 rows.

BODY RINGS. Collum with lateral lobes broadly rounded, with ca 9 striae, slightly curved ectad (Fig. 48A). Very faintly constriction between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae. Anterior sterna in midbody rings subrectangular, without transverse striae (Fig. 167C).

FIRST LEG-PAIR OF MALES. Coxae (cx) short (less than half of remaining podomere lengths), with the base slightly arched, densely setose, and apically projected (Fig. 49A); prefemoral process (prf) almost vestigial, with mesal region of prefemur whitish, covered by long setae, and ectal region more sclerotized and slightly projected apically (Fig. 49B); 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. 49C); prefemur slightly compressed dorsoventrally; remaining podomeres setose, with long setae mesally.

GONOPODS. Gonocoxa (gcx) elongated, almost twice as long as telopodite, with the base slightly arched; flattened antero-posteriorly (Fig. 49D–F); with rows of papillae mesally. Seminal groove (sg) curved; arising medially on mesal cavity and terminating apically on the seminal apophysis (sa); protruding on squamous region of solenomere. Shoulder (sh) long, subtriangular. Telopodite (tp) as wide as half of gcx, separated from sh by deep depression (Fig. 49D); solenomere (sl) with subtriangular apicomesal process (amp); ectal process (ep) subtriangular, elongated and perpendicular to amp; sa located at mesal portion, visible apically. Internal branch (ib) shovel-shaped, rounded and slightly curved apically, with horizontal plate rounded; setae restricted to the apical region of ib, exceeding seminal region of sl (Fig. 49D–F).

VULVAE. As typical for the genus. Bursa subtriangular, glabrous (Fig. 177D); internal valve subtriangular, with mesal region rounded; operculum narrow, constricted medially; external valve wide, subtriangular.

Distribution

Known only from the central region of the Brazilian State of Bahia (Fig. 180).
