Etymology The name is given in honour of Maria Sibylla Merian, German entomologist, naturalist and scientific illustrator. An adjective.

COLOURATION . Head and pronotum brown, legs light brown, abdomen brown. HEAD . Head capsule wider than long; anterior and posterior margins rounded, posterior angles rather rounded; setation with 2 pairs of equal-sized PCS and PMS arranged in 2 pairs, directed upright. Epicranium with umbilicate and sparse micropunctuation, setation with 1 pair of OS, without FS and PFS. Gena smooth, with 2 OT; sockets of MS and POS umbilicate. Postgena with gular sutures reaching posterior margin of head joining neck pits; anterior part of gula with 1 seta near midline of gular suture and 2 close to posterior margin of gular sutures. Antenna widened towards tip, shorter than head and pronotum combined ( Fig. 19A ); antennomeres 1–11 longer than wide, tomentose pubescence starting from antennomere 4; antennomere 1 equals to antennomeres 2 and 3 combined, antennomere 2 longer than 3. Labrum bilobed, with U-shaped emargination and 2 darker, thicker setae along ⅔ line of lobes; marginal clypeal seta light, nearly same size ( Fig. 19A ; Supp. file 2). THORAX . Pronotum quadrate with umbilicate micropunctures and 2 paramedial and lateral longitudinal rows of setae. Basisternum of prosternum with well-developed longitudinal carina and smooth surface. Elytron wider than long, surface of elytra with umbilicate micropunctures in 10–11 moderately dense longitudinal rows ( Fig. 19A ; Supp. file 2). LEGS . Protibia with 4 well-developed combs of setae; mesotibial apical ctenidium on both sides, inner longer than outer; mesotarsomere 1 longer than mesotarsomere 2, mesotarsomeres 3 and 4 equal to mesotarsomere 2, mesotarsomere 5 longer than mesotarsomere 1; inner ctenidium of metatibia longer than outer; metatarsomere 1 as long as metatarsomere 2, metatarsomere 3 shorter than metatarsomere 1 and equal to metatarsomere 4, metatarsomere 5 longer than metatarsomere 1. ABDOMEN . Male : tergites III–VI with high density of micropunctuation; tergites VII and VIII with low density of micropunctuation, punctures randomly distributed. Posterior margin of tergite and sternite VII straight ( Fig. 19B–C ). Posterior margin of tergite VIII truncate, with lateral angles rounded ( Fig. 19D ). Posterior margin of sternite VIII with midlongitudinal emargination, lateral angles rounded ( Fig. 19E ). Posterior margin of tergite IX divided; aedeagus, median lobe uniformly wide, apex of median lobe with deep median cavity with 2 pairs of elongate processes on each side; bottom of median lobe cavity sclerotised with thin spoon-like lamella tapering upwards from top of parameral side. pLS and pPMS difficult to identify. APS rather small, oval, shorter than elongate processes of median lobe ( Fig. 19F–I ). Female : unknown. Fig. 19. Neolindus sibyllae Guzman, Tokareva & Żyła sp. nov. , holotype, ♂ (KUNHM-ENT). A .
