Diagnostic characters.

Yellowish species with 11 darker spots on thorax ( N. yakushimensis   Kolcsár & Kato, sp. nov. dark yellow species with 11 large dark spots, N. gracilis   without dark spots on thorax). Wing without transverse dark line in costal cell. Brown band running from base of R2+3 to tip of M4 and to m-cu (brown band not reaching wing margin in N. yakushimensis   Kolcsár & Kato, sp. nov.). Dark band along crossveins r-m and m-cu conspicuous. Second sternite with black marking at corner of membranous area, but without other line. Gonostylus with 3 spines (2 spines in N. yakushimensis   Kolcsár & Kato, sp. nov. and N. gracilis   ), aedeagus short, triangular, and acute at tip in lateral view (aedeagus long, rod-shaped in N. yakushimensis   Kolcsár & Kato, sp. nov. and N. gracilis   ). Cercus long and straight, just gently curved upward. Genital opening T-shaped, genital fork cross-shaped, lateral sclerite large, half as long as genital fork.

Redescription.

Body length: male 8.5-12 mm, female: 13-15 mm.

Wing length: male 8.5-12 mm, female 11-12 mm.

Head: Yellowish brown (Fig. 15B, C View Figure 15 ) to brown with grayish pruinosity, some dry specimens with reddish shade, grayish pruinosity not visible on specimens stored in ethanol. Palpi brown, 5-segmented, segments 2-4 subequal in length, last segment elongated, ca. 2-3 × longer than segment 4, measurable only on specimens stored in ethanol. Palpomeres 1 and 2 and tip of palpomere 5 darker. Antenna short, just a little longer than head (Figs 2C View Figure 2 , 15C View Figure 15 ). Antenna yellow to brown, sometimes scape and pedicel darker than remainder of antenna. Flagellum unicolor or gradually lightening to apical end (Fig. 15C View Figure 15 ). Flagellum 13-segmented, flagellomeres gradually narrowing to apical end (Fig. 2C View Figure 2 ).

Thorax: Specimens stored in ethanol whitish yellow. General coloration yellow, dorsal parts somewhat darker yellow in pinned specimens (Fig. 15A View Figure 15 ). Sclerites in lateral view as (Fig. 3 View Figure 3 ). Four uniformly dark spots on presutural area of scutum, 7 dark spots on postsutural area of scutum (Fig. 15C View Figure 15 ).

Legs: General coloration yellow, covered with yellowish setae. Femora without apical dark area, apical part of tibiae brownish, with a few darker setae. Apical ends of tarsomeres light brown. Apical half of tarsomere 4 brown, tarsomere 5 slightly lighter than tarsomere 4 (Fig. 15A View Figure 15 ). Tarsomeres with very small spurs, hardly discernable.

Wing: As in Fig. 4A, F View Figure 4 . Crossvein m-m very long, oblique, connecting close to tip of M4. Dark band extending from base of R2+3 to m-cu and to crossvein m-m, and reaching wing margin. Dark band along crossveins r-m and m-cu conspicuous.

Abdomen: Abdomen covered with relatively long pale setae. Tergites 2-6 in male and 2-7 in female each with a longitudinal narrow black line on lateral side, its length ranging from 1/3-1/2 of tergite length (Fig. 15A View Figure 15 ). Sternite 2 with a short black line at corner of membranous area, but without other line (Fig. 15B View Figure 15 ). Membranous area of sternite 2 as in Fig. 3B View Figure 3 . Sternites 3-6 each with a brown line, a little wider and shorter than tergite line (Fig. 15A View Figure 15 ). Sometimes line on sternite 6 indistinct or absent. Tergites and sternites 7 and 8 dark yellow to brown.

Male terminalia: Dark yellow to brown (Fig. 15A View Figure 15 ). Tergite 9 with posterior margin rounded (Fig. 16A, B View Figure 16 ). Gonocoxite with apical lobe 1.8-1.9 × longer than wide (at middle) and around 1.7-1.8 × longer than tergite 9 in lateral view (Fig. 16E, F View Figure 16 ). Apical lobe of gonocoxite prominent in any view, as long as wide of gonocoxite at middle in lateral view (Fig. 16G, H View Figure 16 ). Ventro-basal lobe of gonocoxite prominent in any view, triangular with rounded inner peak in ventral view (Fig. 16C, D View Figure 16 ). Outer part of gonostylus slender in inner lateral view, with 3 black spines, inner part of gonostylus rod-shaped, 4-5 × longer than wide, tip curved dorsally. Interbase elongated, apical widest part 1.5 × wider than base, in dorsal view (Fig. 16A, B View Figure 16 ). Shape of interbase, directing postero-dorsally, pointed at tip (Fig. 16H View Figure 16 ). Aedeagus short, triangular and pointed in lateral view (Fig. 16I, J View Figure 16 ).

Female terminalia, ovipositor: General coloration dark yellow. Cercus almost straight, only weakly curved upward (Fig. 12E View Figure 12 ). Genital fork cross-shaped, wider at posterior 1/4 of its length (Fig. 12F View Figure 12 ). Lateral sclerite of genital plate large, half as long as genital fork. Genital opening T-shaped, two darker areas between genital opening and genital fork small indistinct (Fig. 12F View Figure 12 ).

Larva: Unknown.

Pupa: Unknown.

Distribution.

Russia: Kuril Islands. Japan: Honshu, Shikoku ( Nakamura 2014; Oosterbroek 2020), first records from Hokkaido and Kyushu (Fig. 17 View Figure 17 ).
