Diagnosis

Neolindus sibyllae Guzman, Tokareva & Żyła sp. nov. is similar to N. apiculus , but can be distinguished by the more broadly rounded posterior margin of tergite VIII and short, flat APS of aedeagus (pointed in N. apiculus ) ( Fig. 19F–I ; Herman 1991: figs 174–175).

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.

Distribution

The species is known only from the type locality in Venezuela (Tachira, San Cristobal, Parque Nacional Chorro El Indio). It was collected in the cloud forest at higher altitude – 1425 m a.s.l.
