Pseudonannolene callipyge – Brölemann 1909: 57. — Jeekel 2004: 88.

Diagnosis

Males of P. callipyge can be easily distinguished from all congeners by having glabrous projections located proximally on the stipes of the gnathochilarium (Fig. 168D).

Etymology

Named after the Greek nouns ‘ kállos ’ = ‘beauty’, and ‘ pug ḗ ’ = in reference to the pygidium, telson. Unspecified in the original description.

Descriptive notes

MEASUREMENTS. 58–60 body rings (1–2 apodous + telson). Males: body length 58–67 mm; maximum midbody diameter 3.8–5 mm. Females: body length 70.5–75 mm; maximum midbody diameter 5–5.2 mm.

COLOR. Body color brownish yellow; head, collum, and antennae darker; prozonites and metazonites anteriorly darker, with a posterior reddish band; legs lighter brown.

HEAD. Antennae long (Fig. 58D), 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 narrow. Stipes of gnathochilarium with glabrous basal projections (Fig. 168D). Ommatidial cluster well-developed, elliptical; ca 40 ommatidia in 5 rows.

BODY RINGS. Collum with lateral lobes rounded, with ca 6 deep striae, slightly curved ectad (Fig. 58A). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae below ozopore. Anterior sterna in midbody rings subrectangular, without transverse striae (Fig. 168D).

FIRST LEG-PAIR OF MALES. Coxae (cx) short (less than half of remaining podomere lengths), subtriangular, with the base arched, densely setose (Figs 59A, 60D); prefemoral process (prf) as wide as half of prefemur, subcylindrical, densely setose up to its median region (Fig. 59B); 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. 59C); prefemur compressed dorsoventrally; remaining podomeres setose.

GONOPODS. Gonocoxa (gcx) elongated, almost twice as long as telopodite, with the base arched; flattened antero-posteriorly (Fig. 59D–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) rounded. Telopodite (tp) almost as wide as gcx (Fig. 59D); solenomere (sl) with apicomesal process (amp) rounded; ectal process (ep) short, subtriangular, separating from amp by notch; sa located at mesal portion, slightly visible apically. Internal branch (ib) subtriangular, narrow, surrounding the base of tp as a shield; with torsion of 180° in the distal portion; ib with long setae along its entire margin slightly exceeding apically seminal region of sl (Fig. 59D–F).

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

Distribution

Known from the Atlantic Forest in the southern and northeastern Paraná State, Brazil (Fig. 181); some records from limestone caves in the Açungui Limestone Group.
