Pseudonannolene caulleryi – Mauriès 1987: 77 (lectotype and paralectotypes designations). — Jeekel 2004: 88.

Diagnosis

Males of P. caulleryi resemble those of P. albiventris and P. mesai by having a large trunk of the telopodite, but differing by an elongated gonocoxa; internal branch subtriangular; solenomere with ectal process directed horizontally ( Fig. 61 ).

Etymology

Patronym honoring the collector Professor Caullery ( Brölemann 1929).

Descriptive notes

Description adapted from Brölemann (1929: 16) to supplement original description and to introduce gonopod terminology.

MEASUREMENTS. 51–53 body rings (2–3 apodous + telson). Males: body length 34–37 mm; maximum midbody diameter 2.42–2.48 mm. Females: body length 36 mm; maximum midbody diameter 2.4 mm.

FIRST LEG-PAIR OF MALES. Coxae (cx) short (less than half of remaining podomere lengths), subtriangular, with the base arched, densely setose mainly on distal region; prefemoral process (prf) short (less than half of prefemur), subcylindrical, densely setose up to its median region.

SECOND LEG-PAIR OF MALES. Coxa (cx) large and rounded; penis (pn) located at proximal region, rounded, not extended basally; prefemur compressed dorsoventrally; remaining podomeres setose.

GONOPODS. Gonocoxa (gcx) elongated, almost three times longer than telopodite, subrectangular; antero-posteriorly flattened ( Fig. 61A ); with rows of papillae mesally. Seminal groove (sg) terminating apically on the seminal apophysis (sa). Shoulder (sh) subtriangular. Telopodite (tp) as wide as half of gcx; swollen basally; solenomere (sl) with apicomesal process (amp) subtriangular; ectal process (ep) subtriangular, perpendicular to amp; sa located at mesal portion. Internal branch (ib) shovel-shaped, with setae along its entire margin slightly exceeding apically seminal region of sl ( Fig. 61 ).

Distribution

Known only from the type locality Canoinhas, Santa Catarina State, Brazil ( Fig. 182 ).

Comments

The examination of the lectotype and paralectotypes (two males and one female) deposited at the Muséum national d’histoire naturelle, Paris, France (MNHN), was not possible during this study.
