Diagnosis
Habitus of N. maya sp. nov. resembles that of N. punctogularis, but these species are separated by characters of abdominal sclerites and the aedeagus. N. maya differs from N. punctogularis in the shape of the posterior margin of sternite VII, which narrows towards the apex with a moderately deep concave middle emargination in N. maya and oblique rest of the posterior margin on the sides of the emargination (Fig. 8C). In contrast, in N. punctogularis, the margin is straight and the emargination is bordered by wide rounded processes (Herman 1991: fig. 207). Moreover, N. maya differs in the shape of the posterior margin of sternite VIII with V-shaped emargination and a narrow elevated midlongitudinal invagination on the sternite (Fig. 8E), while N. punctogularis lacks the invagination (Herman 1991: fig. 205); in the shape of the posterior margin of tergite VIII, with the middle acute lobe longer than the 2 lateral acute lobes (Fig. 8D), in contrast to all lobes almost equal in length in N. punctogularis (Herman 1991: fig. 206); and in a different shape of the median lobe of the aedeagus, as well as apical arms of pPMS (Herman 1991: fig. 204; Fig. 8F–G).
Etymology
The name honours the Maya communities that inhabit the type locality in Mexico. A noun in apposition.

COLOURATION. Shiny black body and appendages; abdominal intersegmental membrane between segments III and IV dark brown, rest black.
HEAD. Head capsule wider than long; anterior margin straight; posterior margin rounded, 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 2–3 pairs of PFS in rows parallel to FS, without OS. Gena with irregular surface, with depression from mandibular base to posterior margin of head; setation with 1 OT, MS, and POS; sockets of MS and POS umbilicate. 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. Neck with foramen magnum occupying ¾ of occiput. Antenna thin, longer than head and pronotum combined (Fig. 8A); antennomeres longer than wide, tomentose pubescence starting from antennomere 4; antennomere 1 as long as 2 and 3 combined, antennomere 3 longer than 2. Labrum bilobed, with V-shaped emargination (Fig. 8A; Supp. file 2).
THORAX. Pronotum wider than long, with umbilicate micropunctures, 2 paramedial and 2 lateral rows of setae. Prosternum with superior marginal line parallel to anterior margin. Metasternal intercoxal process with 1 pair of rounded processes. Elytron wider than long, surface of elytra with moderately dense umbilicate punctures in 10–11 longitudinal rows (Fig. 8A; Supp. file 2).
LEGS. Protibia with 5–6 well-developed combs of setae; mesotibial apical ctenidium on both sides, inner longer than outer; metatibial apical ctenidium on both sides, inner longer than outer; metatarsomere 1 longer than 2, metatarsomere 2 longer than 3, metatarsomere 3 longer than 4, metatarsomere 5 as long as 2.
ABDOMEN. Male: tergites with low-density randomly distributed micropunctuation. Posterior margin of tergite VII straight (Fig. 8B). Posterior margin of sternite VII with moderate midline emargination bordered by rounded processes (Fig. 8C). Posterior margin of tergite VIII trilobed, median lobe wide with triangle tip, lateral lobes narrow (Fig. 8D). Posterior margin of sternite VIII with midlongitudinal V-shaped emargination ¼ of segment length, lateral angles rounded (Fig. 8E). Posterior margin of tergite IX with midlongitudinal deep emargination in ¾ of segment length; aedeagus, in parameral view, median lobe of even width, apex with moderately deep emargination. pPMS elongate, robust, with 2 acute apical arms bent inwards; arm closer to median foramen longer than arm closer to parameral side. pLS thin, with net-like microsculpture, forming elongate flat processes equal in length to pPMS and slightly longer than APS. APS spoon-shaped, with blunt top, wider than pLS (Fig. 8F–I). Female: unknown.
Distribution
The species is known only from the type locality in Mexico (Chiapas, Laguna Naja). It sets the northernmost border of the distribution for the genus. It was collected at the altitude of 950 m a.s.l. in the montane wet forest by sifting leaf litter and using a Winkler extractor.
