However, in contrast to N. paralellus , this invagination is glabrous (without setation), and the concave deep emargination of the posterior margin of sternite VIII is covering the whole width and has acute lateral ends ( Herman 1991 : fig. 88; Fig. 24E ). Moreover, tergite VIII has a rounded posterior margin, compared to straight margin in N. paralellus ( Herman 1991 : fig. 87; Fig. 24D ), and the aedeagus of N. yotokae has shorter apical invagination on the parameral side compared to these structures in N. paralellus ( Herman 1991 : fig. 85; Fig. 24F–G ). Etymology The name is dedicated to Dr Karla Yotoko, evolutionary biologist, and Camilo Guzman’s PhD advisor. An adjective.

COLOURATION . Head and pronotum brown; legs light brown; abdomen brown. HEAD . Head capsule wider than long; anterior margin sinuate, dorsoventrally deflexed, slightly elevated; posterior margin rounded with emargination in front of neck; posterior angles round; setation with 2 pairs of PCS and 1 row with 8 setae of PMS, central PMS wide apart, setae near neck longer than others. Epicranium with low-density micropunctuation, setation with 1 pair of OS; IOS and SAS displaced towards second and third parts of head. Gena with smooth surface, with depression from mandibular base to posterior margin of head, setation with 2 trichobothria, MS, 1 POS, and 1 PTOS between margin of eye and POT. Postgena with row of 3 setae in line from eye to gular suture; gular sutures reaching posterior margin of head joining neck pits; anterior part of gula without setae, with lateral depressions; midlength of gula with 2 setae; posterior margin of head with 2 setae close to gular sutures. Antenna moniliform from antennomere 3, shorter than head and pronotum combined; antennomeres 1–7 longer than wide, antennomeres 8–11 wider than long, tomentose pubescence starting from antennomere 5; antennomere 1 as long as antennomeres 2 and 3 combined, antennomere 2 longer than 3. Labrum bilobed, with wide quadrate emargination ( Fig. 24A , Supp. file 2). THORAX . Pronotum slightly longer than wide, with umbilicate randomly distributed micropunctures. Prosternal basisternum with longitudinal carina and smooth surface. Mesosternum with scutiform basisternum with scarce tuberculate micropunctuation. Metasternal intercoxal process with 1 pair of rounded processes. Elytron wider than long, shorter than pronotum; surface of elytra with umbilicate micropunctures in 4–6 moderately dense longitudinal rows ( Fig. 24A , Supp. file 2). LEGS . Protibia with 3 well-developed combs of setae; mesotibial apical ctenidium on both sides, inner longer than outer, outer spine-like; mesotarsomeres 1, 2 and 3 as long as mesotarsomere 5 as longer than mesotarsomeres 1, 2, 3 and 4 combined; inner ctenidium of metatibia longer than outer; metatarsomeres 1, 2, 3 and 4 subequal, metatarsomere 5 as long as metatarsomeres 1–3 combined. ABDOMEN . Male : tergites with moderate density of micropunctuation. Posterior margin of tergite VII straight( Fig.24B ).Posterior margin of sternite VII sinuate, with moderately shallow midline emargination, area around emargination invaginated ( Fig. 24C , Supp. file 2). Posterior margin of tergite VIII elongate, rounded ( Fig. 24D ). Posterior margin of sternite VIII with midline concave emargination as long as posterior margin width, with wide longitudinal glabrous stripe throughout entire segment, lateral angles rounded ( Fig. 24E , Supp. file 2). Posterior margin of tergite IX with midlongitudinal deep emargination in ⅓ of segment length, fused; aedeagus, in parameral view, median lobe of uniform width along sides, apex of median lobe with 2 lateral flattened rounded processes. pPMS and pLS absent. APS short, triangular, flattened, no longer than median lobe, partially covering median foramen ( Figs. 24F–I ). Female : unknown. Distribution The species is known from the type locality in Venezuela ( Aragua , Rancho Grande Biological Station). It was collected in the cloud forest at high altitude ( 1550 m a.s.l.) by sifting leaf litter.
