Diagnosis
Males of P. nicolau sp. nov. can be distinguished from those of all other species of Pseudonannolene by having apicomesal, medial, and ectal processes on the solenomere (Fig. 160D).
Etymology
The species epithet is a noun in apposition derived from the type locality Fazenda São Nicolau, Cotriguaçu, Mato Grosso, an important area of reforestation and environmental education in the Amazon rainforest.

Description
MEASUREMENTS. 55–61 body rings (1 apodous + telson). Males: body length 65–71.5 mm; maximum midbody diameter 3.1–4.5 mm. Females: body length 68.4–78.5 mm; maximum midbody diameter 3.9–5.5 mm.
COLOR. Body color brownish grey; head, antennae, and collum darker; prozonites anteriorly greyish; metazonites with a medial band darker and a posterior lighter; legs brownish.
HEAD. Antennae short (Fig. 164B), just reaching back to end of ring 5 when extended dorsally; antennomeres elongated; relative antennomere lengths 1<2≈3>4>5≈6>7. Mandibular cardo with ventral margin swollen. Ommatidial cluster well-developed, elliptical; ca 20 ommatidia in 4 rows.
BODY RINGS. Collum with lateral lobes rounded, with ca 12 shallow striae, slightly curved ectad posteriorly (Fig. 159A). 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. 174E).
FIRST LEG-PAIR OF MALES. Coxae (cx) elongated (as long as the sum of remaining podomere lengths), subrectangular, with the base arched and expanded, densely setose (Fig. 160A); prefemoral process (prf) as long as half of prefemur, subcylindrical, densely setose along the entire ventral region (Fig. 160B); 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. 160C); prefemur compressed dorsoventrally; remaining podomeres setose.
GONOPODS. Gonocoxa (gcx) rounded, basally expanded and progressively less wide, with the base arched; antero-posteriorly flattened (Fig. 160D–F); 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 (Figs 160D, 216D, 217B); solenomere (sl) with apicomesal process (amp) short, subtriangular; medial process (mp) present, subtriangular; ectal process (ep) elongated, projected ectad; sa located at medial portion on mp, elongated, visible apically. Internal branch (ib) swollen and rounded apically, with large horizontal plate covering entirely trunk of tp in anal view; setae restricted to the apical region of ib not exceeding seminal region of sl (Fig. 160D–F).
VULVAE. As typical for the genus. Bursa clearly subtriangular, glabrous (Fig. 179I); internal valve subtriangular, acuminated apically; operculum narrow, slightly curved ectad; external valve subtriangular, covering operculum basally.
Distribution
Known only from the type locality Fazenda São Nicolau, Cotriguaçu, Mato Grosso State, Brazil (Fig. 191), an important region of international efforts for reforestation in the Amazonian region (see Rodrigues et al. 2011, 2019).
Species inquirendae
Because crucial aspects for proper identification such as morphology of the gonopod, first and second leg-pair of males were not described or sufficiently documented in the original descriptions and types poorly preserved, the following species are considered species inquirendae:
