Pseudonannolene mesai – Iniesta & Ferreira 2013b: 366; 2013c: 78.
Diagnosis
Males of P. mesai resemble those of P. curvata sp. nov., P. erikae, and P. bucculenta sp. nov. by having a mesally curving telopodite, but differing from those species by a larger trunk of the telopodite, projected laterad (Fig. 94D).
Etymology
Patronym honoring the collector A. Mesa (Fontanetti 2000).

Descriptive notes
MEASUREMENTS. 54–60 body rings (1–2 apodous + telson). Males: body length 60.8–61.8 mm; maximum midbody diameter 3.1–3.6 mm. Females: body length 71.6–81.4 mm; maximum midbody diameter 4.6–4.8 mm.
COLOR. Body color brownish grey; head, collum, antennae and legs brownish darker; prozonites anteriorly greyish; metazonites with a medial brown band and a posterior lighter.
HEAD. Antennae long (Fig. 163N), 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. Ommatidial cluster well-developed, elliptical; ca 33 ommatidia in 5 rows.
BODY RINGS. Collum with lateral lobes rounded, with ca 9 striae, slightly curved ectad (Fig. 93A). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae below ozopore. Anterior sterna in midbody rings subrectangular, with 7 transverse striae (Fig. 170D).
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 (Fig. 94A); prefemoral process (prf) as wide as half of prefemur, subcylindrical, densely setose up to its median region (Fig. 94B); 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. 94C); prefemur compressed dorsoventrally; remaining podomeres setose.
GONOPODS. Gonocoxa (gcx) rounded and elongated, almost twice as long as telopodite, with the base arched; antero-posteriorly slightly flattened (Fig.94D–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) inconspicous. Telopodite (tp) large, strongly curved mesad, projected laterad (Fig. 94D); solenomere (sl) with small squamous region; apicomesal process (amp) subtriangular; ectal process absent; sa located at mesal portion, slightly visible apically. Internal branch (ib) short and narrow, subtriangular, surrounding basally tp as a shield; ib with setae along its entire margin exceeding apically seminal region of sl (Fig. 94D–F).
VULVAE. As typical for the genus. Bursa subtriangular, glabrous (Fig. 178C); internal valve subtriangular, with mesal region rounded; operculum narrow; external valve wide, subtriangular.
Distribution
The species occurs in the Atlantic Forest from the coastal region of São Paulo State, Brazil (Fig. 185).
