Diagnosis

Males of P. parvula slightly resemble those of P. spelaea by having the solenomere rounded apically and with seminal apophysis located mesally ( Fig. 104D–F View Fig ), but differing by the absence of a squamous membrane on the seminal apophysis ( Fig. 104D View Fig ); and by the presence of spiniform setae in the proximal region of the mentum and stipes ( Fig. 171C View Fig ).

Etymology

Named after the Latin adjective ‘ parvus ’ = ‘few’, ‘small’, plus the suffix ‘-ulus’ (feminine ‘-ula’). Unspecified in the original description.

Descriptive notes

MEASUREMENTS. 58–61 body rings (1–2 apodous + telson). Males: body length 51.9–55.4 mm; maximum midbody diameter 3.4–4.9 mm. Females: body length 56–57.9 mm; maximum midbody diameter 4–4.1 mm.

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

HEAD. Antennae short ( Fig. 164E 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 narrow. Mentum and stipes of gnathochilarium with scattered spiniform setae ( Fig. 171C View Fig ). Ommatidial cluster well-developed, elliptical; ca 30 ommatidia in 5 rows.

BODY RINGS. Collum with lateral lobes rounded, with ca 6 shallow striae, slightly curved ectad ( Fig. 103A View Fig ). 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. 171C View Fig ).

FIRST LEG-PAIR OF MALES. Coxae (cx) short (less than half of remaining podomere lengths), subtriangular, with the base arched and strongly expanded, densely setose ( Fig. 104A View Fig ); prefemoral process (prf) as wide as half of prefemur, subcylindrical, curved ectad, densely setose up to its median region ( Fig. 104B View Fig ); 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. 104C View Fig ); prefemur compressed dorsoventrally; remaining podomeres setose.

GONOPODS. Gonocoxa (gcx) elongated, almost twice as long as telopodite, with the base slightly arched; antero-posteriorly flattened ( Fig. 104D–F View Fig ); 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 ( Fig. 104D View Fig ); solenomere (sl) with apicomesal process (amp) rounded; ectal process (ep) short, nearly not distinguished from amp by inconspicuous notch; sa located at mesal portion, slightly visible apically. Internal branch (ib) subtriangular, narrow, surrounding basally tp as a shield; setae starting at midlength of ib exceeding seminal region of sl ( Fig. 104D–F View Fig ).

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

Distribution

Known from the region of Iguaçu Falls and surrounding forests on the border of the Argentine province of Misiones, Paraguayan department of Alto Paraná, and the Brazilian state of Paraná ( Fig. 186 View Fig ).

Comments

Male syntypes from Alto dell’Iguazú and Puerto Bertoni described by Silvestri (1902) were not found. Nevertheless, syntypes from Bella Vista ( Fig. 105C View Fig ) and topotypes from Foz do Iguaçu were examined ( Fig. 105D View Fig ).
