Diagnosis

Among species with two pairs of head trichobothria, N. yotokae Guzman, Tokareva & Żyła sp. nov. resembles N. paralellus with a wide midlongitudinal invagination in sternite VIII and the structure of aedeagus. 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.
