Diagnosis
This species is similar to N. apiculus and N. campbelli in having a broad emargination of sternite VIII ( Herman 1991: figs 168, 173; Fig. 4E View Fig ). However, the structure of the aedeagus in N. bicornis Guzman, Tokareva & Żyła sp. nov. is different ( Herman 1991: figs 170, 174; Fig. 4F–I View Fig ). It resembles the aedeagus of N. triangularis Guzman, Tokareva & Żyła sp. nov., but it differs by having a rounded base of the median lobe and a narrower pLS in their middle part (the base of the median lobe acute in N. triangularis ) ( Figs 4F–I View Fig , 20F–I View Fig ).
Etymology
The name is a combination of the Latin prefix ‘ bi ’ meaning ‘two’ and the Latin word ‘ cornum ’, which means ‘a horn’. It describes the characteristic form of apical aedeagal sclerites. An adjective.

COLOURATION. Head dark brown; pronotum brown; legs light brown; abdomen brown.
HEAD. Head capsule wider than long; anterior margin sinuate, dorsoventrally deflexed, slightly elevated; posterior margin straight with emargination in front of neck; posterior angles straight; setation with 1 pair of PCS and 1 row of PMS. Epicranium with umbilicate, low-density micropunctuation, setation with 1 pair of FS and 1 pair of PFS, without OS. Gena with depression from mandibular base to middle of eye, setation with 1 OT, MS, POS and PTOS; sockets of MS and POS umbilicate. 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. Neck with foramen magnum occupying ¾ of occiput. Antenna moniliform from antennomere 3, shorter than head and pronotum combined; antennomeres longer than wide, tomentose pubescence starting from antennomere 3; antennomere 1 shorter than antennomeres 2 and 3 combined, antennomere 3 longer than 2. Labrum bilobed, emargination deep, U-shaped, with 2 dark, thick seta in median line of labrum lobes ( Fig. 4A View Fig , Supp. file 2).
THORAX. Pronotum slightly wider than long, with randomly distributed umbilicate micropunctuatoin and slightly convex anterior margin. Basisternum of prosternum with tuberculate micropunctuation. Metasternal intercoxal process with 1 pair of acute processes. Elytron longer than wide, surface of elytra with moderately dense umbilicate punctures in 8–10 longitudinal rows ( Fig. 4A View Fig ; Supp. file 2).
LEGS. Protibia with 4 well-developed combs of setae, apical comb longitudinal, composed of widely separated, thick setae; mesotibial apical ctenidium on both sides, inner longer than outer; mesotarsomere 1 as long as mesotarsomere 2, mesotarsomere 3 shorter than mesotarsomere 1, but as long as mesotarsomere 4, mesotarsomere 5 as long as mesotarsomere 1; inner ctenidium of metatibia longer than outer; metatarsomere 1 longer than metatarsomere 2, metatarsomere 2 longer than metatarsomere 3, metatarsomere 4 as long as metatarsomere 3, metatarsomere 5 shorter than 1 but longer than 2.
ABDOMEN. Male: posterior margin of sternite VII sinuate, with midlongitudinal emargination and rounded lateral angles ( Fig. 4C View Fig ). Posterior margin of tergite VIII with elongate rounded apex ( Fig. 4D View Fig ). Posterior margin of sternite VIII with median V-shaped emargination and rounded lateral angles ( Fig. 4E View Fig ). Posterior margin of tergite IX with midlongitudinal deep emargination in ¾ of segment length, wider at margin and narrow towards apex; aedeagus, median lobe rounded at base, widening apically and well-sclerotised; pLS fused into flattened arcuate sclerite of almost even width with 2 acute processes on each side protruding distad from median foramen and ending bent to antiparameral side. APS flattened, arcuate, smaller than pLS, with 2 acute processes on each side protruding distad from median foramen and ending bent to parameral side, shorter than processes of pLS. pPMS not visible ( Fig. 4F–I View Fig ). Female: lack of emargination on abdominal segments.
Distribution
This species is known from the type locality in French Guyana (Cayenne, Roura) and the surrounding area. It was collected by a flight interception trap at an altitude of 240–280 m a.s.l.
