Diagnosis
This species is similar to N. milleri in shape of sternite and tergite VIII. However, in N. elegans Guzman, Tokareva & Żyła sp. nov., the posterior margin of sternite VII has a wide middle emargination with a straight middle part, delimited on sides by 2 long acute processes ( Fig. 5C View Fig ). In contrast, N. milleri has a shallower emargination lacking acute processes on the sides ( Herman 1991). Furthermore, the aedeagus of N. elegans displays a complex composition of apical sclerites surrounding the median foramen of the median lobe ( Fig. 5F–I View Fig ), while the aedeagus of N. milleri has a simpler arrangement of sclerites ( Herman 1991: fig. 189).
Etymology
The name is derived from the Latin word ‘ elegans ’, which means ‘elegant’ or ‘tasteful’. It refers to the symmetry of the aedeagus in parameral view, particularly the straight angle between the median lobe apex and some apical sclerites. An adjective.

Epicranium with umbilicate, low-density micropunctuation, setation with 1 pair of FS and 1 pair of PFS, without OS. Gena with depression around trichobothria, setation with 1 OT, MS, POS and PTOS; sockets of POS concave. Postgena with row of 2 setae in line from eye to gular suture; gular sutures reaching posterior margin of head, joining neck pits; anterior part of gula with 2 setae; posterior margin of head with 2 setae close to gular sutures. Neck with foramen magnum occupying ¾ of occiput. Antenna moniliform from antennomere 3, shorter than head and pronotum combined; antennomeres longer than wide; antennomeres 4–11 with tomentose pubescence; antennomere 1 as long as antenomeres 2 and 3 combined; antennomere 3 longer than 2. Labrum bilobed, with U-shaped emargination, with 2 dark thick seta in median line of labrum lobes ( Fig. 5A View Fig ; Supp. file 2).
THORAX. Pronotum slightly wider than long, with umbilicate micropunctures, 2 paramedial and 2 lateral rows of setae. Metasternum with umbilicate micropunctuation in longitudinal rows, metasternal intercoxal process with pair of barely visible rounded processes. Elytron longer than wide, surface of elytra with moderately dense umbilicate punctures in 10–12 longitudinal rows ( Fig. 5A View Fig ; Supp. file 2).
LEGS. Protibia with 3 well-developed combs of setae; mesotibial apical ctenidium on both sides, inner longer than outer; mesotarsomere 1 longer than 2, mesotarsomeres 3 and 4 as long as mesotarsomere 2, mesotarsomere 5 longer than 1; inner ctenidium of metatibia longer than outer; metatarsomere 1 as long as 2, metatarsomere 3 shorter than 1 and as long as metatarsomere 4, metatarsomere 5 longer than metatarsomere 1.
ABDOMEN. Male: tergites with low-density random micropunctuation. Posterior margin of tergite VII slightly convex, almost straight ( Fig. 5B View Fig ). Posterior margin of sternite VII with wide midpoint emargination with straight angles, delimited by 2 long teeth-like processes with acute ends ( Fig. 5C View Fig ). Posterior margin of tergite VIII with elongate rounded apex ( Fig. 5D View Fig ). Posterior margin of sternite VIII with midlongitudinal V-shaped emargination, lateral angles rounded ( Fig. 5E View Fig ). Posterior margin of tergite IX with midlongitudinal deep emargination in ¾ of segment length; aedeagus, median lobe vase-shaped, rounded at base, broadening towards apex; apex notched on parameral side with elongate median hole or cavity not reaching basal foramen elevation, apical part of median lobe with 2 pairs of processes near middle, as part of joint with movable pPMS. pPMS robust, of complex form, protruding upwards, shorter than APS, upper part curved on parameral side, with multiple small denticles on curved top. pLS small, oval, obscure, shorter than other apical sclerites. APS spoon-shaped, longer than pLS and pPMS, with central emargination having acute tip and 2 acute narrow short processes on sides ( Fig. 5F–I View Fig ). Female: unknown.
Distribution
The species is known only from the type locality in French Guyana (Saint-Laurent-du-Maroni, Saül). It was collected on Monts La Fumée between 230–400 m a.s.l. from fungus log.
