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.

COLOURATION. Whole body and appendices brown.
HEAD. Head capsule wider than long; anterior margin sinuate, dorsoventrally deflexed, slightly elevated; posterior margin rounded, with emargination in front of neck; posterior angles rounded, setation with 1 pair of PCS, 1 row of PMS, and longer setae near posterior margin before neck. Epicranium with umbilicate, low-density micropunctuation, setation with 1 pair of FS and 2 pairs of PFS, without OS. Gena with irregular surface, with depression from mandibular base to middle of eye, setation with 1 OT, MS, and POS; sockets of MS and POS umbilicate. Postgena with row of 1 or 2 setae in line from eye to gular suture; gular sutures reaching posterior margin of head joining neck pits; anterior part of gula with 2 setae; posterior margin of head with 2 setae near gular sutures. Neck with foramen magnum occupying ⅔ of occiput. Antenna moniliform from antennomere 5, shorter than head and pronotum combined (Fig. 12A); antennomeres longer than wide, tomentose pubescence from antennomere 4; antennomere 1 as long as antennomeres 2 and 3 combined, antennomere 3 longer than 2. Labrum bilobed, with U-shaped emargination (Fig. 12A; Supp. file 2).
THORAX. Pronotum quadrate, with umbilicate randomly distributed micropunctures. Metasternal intercoxal process with 1 pair of acute processes, joining medially in U-like invagination. Elytron longer than wide, surface of elytra with moderately dense umbilicate punctures in 10–11 longitudinal rows (Fig. 12A; Supp. file 2).
LEGS. Protibia with 4 well-developed combs of setae; apical comb longitudinal, composed of widely separated, thick setae; mesotibial apical ctenidium on both sides, inner longer than outer; mesotarsomere 1 as long as 2, mesotarsomere 3 equals to 4, shorter than 2, mesotarsomere 5 longer than 1; inner ctenidium of metatibia longer than outer; metatarsomere 1 longer than 2, metatarsomeres 3 and 4 as long as metatarsomere, metatarsomere 5 as long as metatarsomere 1.
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.
