Diagnosis
Neolindus luxipenis Guzman, Tokareva & Żyła sp. nov. is most similar to N. lirellus and N. brachiatus. However, N. luxipenis differs from N. lirellus in sternite VII by the more pronounced central process of posterior margin, and tergite VIII, where the posterior margin is rounded (Fig. 7C–D; Herman 1991: figs 108–109, 111). In comparison to N. brachiatus, sternite VII of N. luxipenis has a central narrower emargination, with 2 protruded processes on each side and invaginated surface around emargination; in N. brachiatus central emargination is wider and the processes are less protruded (Fig. 7C; Herman 1991: fig. 101).
Etymology
The name combines the Latin word ‘ luxus ’ for ‘luxury’ or ‘extravagant’ and ‘ penis ’ which addresses the aedeagus here. It refers to an elaborate structure of aedeagus in the species. An adjective.

Labrum bilobed, emargination U-shaped, with 2 dark thick seta in median line of labrum lobes (Fig. 7A; Supp. file 2).
THORAX. Pronotum nearly quadrate, with umbilicate micropunctures and 2 distinct paramedial rows of setae; anterior margin slightly convex. Metasternal intercoxal process with 1 pair of obtuse processes. Elytron longer than wide, surface of elytra with umbilicate micropunctures in 5–7 moderately dense longitudinal rows (Fig. 7A; Supp. file 2).

Posterior margin of tergite VIII apically extended and rounded (Fig. 7D). Sternite VIII with broad midlongitudinal emargination covering ⅓ of segment length, starting as narrow and widening towards rounded lateral edges (Fig. 7E). Posterior margin of tergite IX with midlongitudinal deep emargination ½ of segment length, fused; aedeagus, median lobe with uniform width from base to apex, apex emarginate; pLS flat with rounded edges, expanded laterally and folded inward; APS complex with 2 processes, each process with 2 arms, apical arm acute, frontal arms bend downward and subdivided to long tooth and group of several small teeth at top of acute process; pPMS absent (Fig. 7F–I). Female: unknown.
Distribution
This species is known only from the type locality in Bolivia (Cochabamba, Cochabamba, Valle de Sajta Biological Station). It was collected at a lower altitude (300 m a.s.l.) using a flight interception trap.
