Diagnosis
This species resembles N. sinuatus and N. basisinuatus, but can be distinguished by a combination of characters. Unlike in N. sinuatus, the posterior margin of male sternite VIII in N. parasinuatus Guzman, Tokareva & Żyła sp. nov. has a wide emargination with a concave middle part surrounded by invagination on the sclerite (Herman 1991: fig. 199; Fig. 15E). In contrast to N. basisinuatus, the posterior margin of tergite VIII in N. parasinuatus is rounded (Herman 1991: fig. 194; Fig. 15D). In comparison to both species, the aedeagus of N. parasinuatus lacks a pair of setal brushes near the median invagination on the parameral side (Herman 1991: figs 193, 198; Fig. 15F–G).
Etymology
The specific epithet is a combination of ‘ para ’, a Latin prefix that means ‘similar to’ or ‘equal’, and ‘ sinuatus ’ as the name of the species described by Herman (1991), N. sinuatus. It indicates the similarity in the morphology of the aedeagi of the two species. An adjective.

Head capsule wider than long; anterior margin straight; posterior margin slightly convex anteriad with emargination in front of neck; posterior angles rounded; setation with 1 PCS, PMS in moderately dense row. Epicranium with low-density micropunctuation, setation with 1 pair of FS, 1 pair of OS, and 3 pairs of PFS. Gena with irregular surface, with depression from mandibular base to middle of eye, with 1 OT; socket of mandibular seta umbilicate, sockets of POS with raised edges. Postgena with row of 3 setae in line from eye to gular suture; posterior margin close to gular sutures with 2 setae; gular sutures straight, extended to posterior margin of head; anterior part of gula with 2 rows of setae. Antenna shorter than head and pronotum combined (Fig. 15A), moniliform starting from antennomere 5; antennomeres 1–7, 10 and 11 longer than wide, antennomeres 8 and 9 wider than long; tomentose pubescence starting from antennomere 4; antennomere 1 as long as antennomeres 2 and 3 combined, antennomere 3 longer than 2. Labrum tetralobed, with 2 dark thick setae in median line of lobes, central lobes more developed than lateral lobes, emargination deep, V-shaped (Fig. 15A; Supp. file 2).
THORAX. Pronotum quadrate, with umbilicate micropunctures, 2 paramedial and 2 lateral distinct rows of setae. Basisternum of prosternum triangular, with row of 8 setae on anterior margin, longitudinal ridge, and wrinkled surface. Metasternal intercoxal process with 1 pair of acute long processes. Elytron longer than wide, surface of elytra with punctures in 7–8 longitudinal rows (Fig. 15A; Supp. file 2).
LEGS. Protibia with 3 well-developed combs of setae, 1 anterior row covering ⅔ of tibia length; mesotibial apical ctenidium only on inner side; outer margin with row of spines; metatarsomere 1 as long as metatarsomere 2, metatarsomere 3 as long as metatarsomere 4 and shorter than 1, metatarsomere 5 as long as metatarsomere 1.
ABDOMEN. Male: tergites with sparse micropunctures. Anterior margin of tergite VII with 4 basal canals with elevated margin, posterior margin straight (Fig. 15B). Posterior margin of sternite VII straight (Fig. 15C). Anterior margin of tergite VIII with 4 internal canals, central canals fused, forming inverted pentagon; posterior margin rounded (Fig. 15D). Posterior margin of sternite VIII with wide and shallow midlongitudinal emargination with straight middle part and rounded lateral angles (Fig. 15E). Posterior margin of tergite IX with midlongitudinal deep emargination of ¾ of segment length (Herman 1991: fig. 192); aedeagus, median lobe rounded at base, with parallel lateral sides, apex on parameral side deeply notched with elongate, blunt-end median hole or cavity. pPMS shell-shaped, triangular, robust, immersed into opening of median foramen. pLS absent. APS flattened, wider than long, shorter than pPMS; 1 pair of inner sclerites attached to pPMS and single, symmetrical, flattened sclerite attached to paired ones (Fig. 15F–I). Female: unknown.
Distribution
The species is known only from the type locality in Colombia (Amazonas, Leticia, Parque Nacional Natural Amacayacu). It was collected by Malaise trap at low altitude.
