Diagnosis

Neolindus ornatus Guzman, Tokareva & Żyła sp. nov. is similar to N. cuneatus in sternite and tergite VIII ( Fig. 12C, D and figs 177, 178 in Herman 1991, respectively). However, N. ornatus has longer pPMS and longer, bifid pLS of aedeagus than N. cuneatus ( Herman 1991: fig. 179; Fig. 12F–I ).

Etymology

The name is derived from the Latin word ‘ ornatus ’ meaning ‘adorned’ or ‘equipped’, referring to the complex structure of the aedeagus. An adjective.

ABDOMEN. Male: tergites with low-density micropunctuation. Posterior margin of tergite VII straight ( Fig. 12B ). Posterior margin of sternite VII slightly emarginated, with small midpart invagination ( Fig. 12C ). Posterior margin of tergite VIII truncate ( Fig. 12D ). Posterior margin of sternite VIII with midlongitudinal V-shape emargination, with elevated area in midpart ( Fig. 12E ). Posterior margin of tergite IX with midlongitudinal deep emargination in ¾ of segment length, divided; aedeagus, in parameral view, median lobe basally narrower, and wider in middle, apex deeply invaginated, with prominent sclerotised rounded processes on each side; foramen triangular, with round angles; APS not visible; pLS flattened with 2 arms, apical arm, curving towards non-parameral side, ending in acute tip, basal arm projecting to parameral side ending as acute tip; pPMS flattened with 2 arms, apical arm tapering to end as acute tip, basal arm projects in parameral side with rounded end ( Fig. 12F–I ). Female: unknown.

Distribution

The species is known from the type locality in French Guyana (Cayenne, Roura, near Matoury) and the surrounding area. It was collected at low altitudes using a flight interception trap.
