Diagnosis
Males of P. alata sp. nov. can be distinguished from those of all other species of Pseudonannolene by having a large, rounded projection on the telopodite ( Fig. 146D View Fig ).
Etymology
The species epithet is derived from the Latin adjective ‘ alata ’ = ‘winged’, in reference to the ectal projection on the telopodite.

Description
MEASUREMENTS. 53–55 body rings (1–2 apodous + telson). Males: body length 43.8–64.8 mm; maximum midbody diameter 3.2–4.5 mm. Females: body length 56.5–72.2 mm; maximum midbody diameter 4–5.4 mm.
COLOR. Body color brownish grey; head and collum darker; prozonites anteriorly greyish; metazonites with a medial band darker and a posterior reddish; antennae and legs reddish.
HEAD. Antennae short ( Fig. 163C 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. Ommatidial cluster well-developed, elliptical; ca 40 ommatidia in 6 rows.
BODY RINGS. Collum with lateral lobes rounded, with ca 6 deep striae, strongly curved ectad ( Fig. 145A View Fig ). 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. 175B View Fig ).
FIRST LEG-PAIR OF MALES. Coxae (cx) elongated (as long as the sum of remaining podomere lengths), subtriangular, with the base slightly arched and expanded, densely setose mainly on distal region ( Fig. 146A View Fig ); prefemoral process (prf) as wide as half of prefemur, subcylindrical, densely setose along in its entire extension ( Fig. 146B View Fig ); remaining podomeres with setae along the mesal region.
SECOND LEG-PAIR OF MALES. Coxa (cx) large and subrectangular; penis (pn) located at proximal region, rounded, not extended basally ( Fig. 146C 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. 146D–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 (sh) inconspicuous. Telopodite (tp) almost as wide as gcx ( Figs 146D View Fig , 215B), with large and rounded laterad projection; solenomere (sl) expanded laterad, rounded, with apicomesal process (amp) subtriangular; ectal process absent; sa located at mesal portion, visible apically. Internal branch (ib) subtriangular, narrow, surrounding basally tp as a shield; ib with setae along its entire margin nearly exceeding apically seminal region of sl ( Fig. 146D–F View Fig ).
VULVAE. As typical for the genus. Bursa subtriangular, glabrous ( Fig. 179K View Fig ); internal valve subtriangular, mesally rounded; operculum narrow, curved ectad, slightly compressed basally; external valve subtriangular.
