Diagnosis
The unusual head chaetotaxy of this species including 2 pairs of PCS, the morphology of abdominal apical sclerites, and the aedeagus make this species similar to N. punctogularis. Neolindus niger Guzman, Tokareva & Żyła sp. nov. differs from it by the shiny black colouration of the head and pronotum (brown in N. punctogularis) and the presence of setae and paired long midlongitudinal invagination anteriorly to the emargination of abdominal sternite VIII (absent in N. punctogularis) (Herman 1991: fig. 205; Fig. 11E).
Etymology
The name is a Latin adjective ‘ niger ’ which means ‘shiny black’ and refers to the colouration of specimens.

Postgena with row of 3 setae in line from eye to gular suture and 1 seta parallel to PTOS on each side; gular sutures reaching posterior margin of head joining neck pits; anterior part of gula with irregular row of 6–8 setae. Neck with foramen magnum occupying ½ of occiput.Antenna thin and elongate, longer than head and pronotum combined (Fig. 11A); antennomeres longer than wide; tomentose pubescence starting from antennomere 4; antennomere 1 as long as antennomeres 2 and 3 combined, antennomere 3 longer than 2. Labrum bilobed, with V-shaped emargination and 2 dark thick setae in median line of lobes (Fig. 11A; Supp. file 2).
THORAX. Pronotum slightly wider than long. Basisternum of prosternum with row of 8 setae on anterior margin. Metasternal intercoxal process with 1 pair of rounded processes. Elytron longer than wide, surface of elytra with moderately dense umbilicate punctures in 8–10 longitudinal rows (Fig. 11A; Supp. file 2).
LEGS. Protibia with 5 well-developed combs of setae; mesotibial apical ctenidium on both sides, inner longer than outer; mesotarsomere 1 equal to mesotarsomere 2, mesotarsomere 3 shorter than 1 and as long as 4, mesotarsomere 5 longer than 1; inner ctenidium of metatibia longer than outer; metatarsomere 1 longer than 2, metatarsomere 2 longer than 3, metatarsomere 4 equals 3, metatarsomere 5 equals 2.
ABDOMEN. Male: tergites III–VI with high density of micropunctuation, tergites VII and VIII with low density of micropunctuation. Tergite VII with posterior margin straight (Fig. 11B). Sternite VII with posterior margin moderately emarginate, bordered by obtuse distinct processes (Fig. 11C). Tergite VIII with posterior margin trilobed, central lobe triangular, apically acute; lateral lobes slightly acute (Fig. 11D). Sternite VIII posterior margin with broad emargination; with pair of midlongitudinal invaginations on sides of flat elevation in middle (Fig. 11E). Tergite IX with posterior margin deeply emarginated to ¾ of segment length (Fig. 11A; as in Herman 1991: fig. 137); aedeagus, median lobe medially widened, apex with deep emargination bordered by rounded processes; pLS thin, with net-like microsculpture, forming elongate flat processes; APS spoon-shaped, with rounded apical edge; pPMS sickle-like, wider than long in lateral view; apical arm closer to parameral side, bent towards it, apical arm closer to antiparameral side, straight (Fig. 11F–I). Female: unknown.
Distribution
This species is known from the type locality in Costa Rica (Puntarenas, Rincon de Osa) and Corcovado National Park (Puntarenas). It was collected in a cloud forest at a low altitude using flight interception trap.
