Diagnosis

This species resembles N. parautriensis sp. nov. and N. maya sp. nov. in terms of habitus, but can be distinguished from them by the characters of the apical sclerites of the aedeagus: pPMS of N. utriensi s sp. nov. is straight, narrower than in N. maya and wider than in N. parautriensis , bearing apical arms of uneven lengths, bent inwards ( Fig. 22F–I ).

Etymology

The species name is derived from the name of the Utría National Natural Park in Chocó, Colombia, which is the type locality. An adjective.

COLOURATION. Head and pronotum dark brown, legs brown, abdomen dark brown.

HEAD. Head capsule wider than long; anterior margin straight; posterior margin straight with emargination in front of neck; posterior angles straight; setation with 1 PCS, PMS in dense straight row. Epicranium with dense micropunctuation, setation with 1 pair of FS, 2 pairs of PFS in row parallel to PMS, and without OS. Gena with irregular surface, with depression from mandibular base to posterior eye margin, and with 1 OT. Postgena with row of 3 setae in line from eye to gular suture, gular sutures not reaching posterior margin of head, anterior part of gula with irregular row of 6–8 setae. Antenna thin, longer 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, with shallow U-shaped emargination ( Fig. 22A ; Supp. file 2).

THORAX. Pronotum wider than long, almost quadrate (ratio 0.87), with umbilicate punctures and 2 paramedial rows of setae. Basisternum of prosternum triangular, with row of 8 setae on anterior margin, longitudinal ridge present, and surface wrinkled. Metasternal intercoxal process with 1 pair of acute spine-like processes. Elytron longer than wide, surface of elytra with moderately dense umbilicate punctures in 6–8 longitudinal rows ( Fig. 22A ; Supp. file 2).

LEGS. Protibia with 4 well-developed combs of setae; mesotibial apical ctenidia on both sides, inner longer than outer; mesotarsomere 1 as long as mesotarsomere 2; mesotarsomeres 3 and 4 shorter than mesotarsomere 1; mesotarsomere 5 longest; metacoxa wider than long; metatarsomere 1 as long as metatarsomeres 2 or 5; metatarsomeres 3 and 4 combined shorter than 5.

ABDOMEN. Tergites with sparse micropunctures. Anterior margin of tergite VIII (base of tergite) with 4 internal canals, elevated, central canals forming inverted pentagon. Anterior margin of sternite VIII with 4 internal canals. Male: posterior margin of tergite VII straight ( Fig. 22B ). Posterior margin of sternite VII with moderate emargination at middle, with acute processes on each side ( Fig. 22C ). Posterior margin of tergite VIII with wide median process with narrow invaginations on sides and acute angles ( Fig. 22D ). Posterior margin of sternite VIII bilobed, with narrow median emargination reaching up to ¼ of segment length, lobes rounded ( Fig. 22E ); posterior margin of tergite IX with midlongitudinal deep invagination at ¾ of segment length ( Asenjo 2011: fig. 12); aedeagus, median lobe broadened at base, apex with moderately deep emargination and rounded processes on each side. pLS thin, with net-like microsculpture, forming elongate flat processes equal in length to pPMS and slightly longer than APS. APS spoon-shaped, wider than pLS, with slightly emarginate apical edge. pPMS elongate, thin, with 2 acute apical arms bent inwards; arm closer to median foramen longer than arm closer to parameral side ( Fig. 4A–B ). Female: posterior margin of sternite VII sinuate; sternite VIII bilobed, slightly emarginate ( Fig. 22F–I ).

Distribution

This species is known only from the type locality in Colombia (Choco, Bahía Solano, Utría National Natural Park). It was collected at a low altitude by Malaise trap.
