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.

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.
