Diagnosis
Neolindus volkeri Guzman, Tokareva & Żyła sp. nov. resembles N. schubarti and N. irmleri in aedeagus morphology. However, in N. volkeri, the median invagination on the parameral side of the median lobe is wider than in the other two species (Herman 1991: fig. 210; Asenjo 2011: fig. 2; Fig. 23F–G). Unlike the two similar species, N. volkeri has a deep midline emargination with a convex median part on the posterior margin of sternite VII, with acute protruding processes on both sides (emargination shallow and without processes in both N. schubarti and N. irmleri) (Herman 1991; fig. 208; Asenjo 2011: fig. 4; Fig. 23C). Additionally, the posterior margin of tergite VIII has deeper pair of emarginations surrounded by invaginated areas (shallower and without invagination in N. schubarti and N. irmleri) (Fig. 23D; Herman 1991: fig. 206; Asenjo 2011: fig. 6).
Etymology
This species is dedicated to the great taxonomist, Volker Assing, who passed away prematurely. He was a renowned specialist in Palaearctic and Oriental Paederinae and described two species of Neolindus.

Metasternal intercoxal process with 1 pair of acute processes. Elytron longer than wide, surface of elytra with umbilicate micropunctures in 8–9 moderately dense longitudinal rows (Fig. 23A; Supp. file 2).

Distribution
The species is only known from the type locality in French Guiana, (Cayenne, Roura). It was collected at a low altitude using a flight interception trap.
