Diagnostic characters.

Yellowish species with 11 dark spots on thorax (7 dark spots in N. okinawensis   Kolcsár & Kato, sp. nov., 11-13 dark spots in N. kuwanai   ). Wing with transverse dark lines in costal cell. Brown marking extending from R2+3 to crossvein m-m (brown marking extending from R2+3 to maximum to base of M1 in N. kuwanai   and N. okinawensis   Kolcsár & Kato, sp. nov.). Sternite 2 without black marking at corner of membranous area (with black marking at corner of membranous area in N. kuwanai   ), a diffuse line positioned same level as line on sternite 3 ( N. kuwanai   without this line, N. okinawensis   Kolcsár & Kato, sp. nov. with any line and dark marking on sternite 2). Gonostylus with 4 or 5 spines (11-14 spines in N. kuwanai   ). Aedeagus short, twice as long as wide, rounded (as long as wide in N. kuwanai   ). Cercus curved upward (straight in N. okinawensis   Kolcsár & Kato, sp. nov.). Female genital opening Y-shaped (T-shaped in N. okinawensis   Kolcsár & Kato, sp. nov.), lateral sclerite 1/3 of length of genital fork (less than 1/5 of length of genital fork in N. kuwanai   and less than 1/6-1/7 of length of genital fork in N. okinawensis   Kolcsár & Kato, sp. nov.), genital fork cross-shaped (spoon-shaped in N. kuwanai   , cross-shaped in N. okinawensis   Kolcsár & Kato, sp. nov. but lateral branch curved caudally).

Redescription.

Body length: male 9.5-11 mm, female: 12-13 mm.

Wing length: male 9.5-10.5 mm, female 10-11 mm.

Head: Light brown to brown (Fig. 8C View Figure 8 ). Palpi brown, 5-segmented, palpomeres 2 to 4 subequal in length, last segment elongated, ca. 1.5 × longer than palpomere 4 in male. Female palpomere 5 almost same length as palpomere 4 or at most 1.3 × longer. Tip of palpomere 5 darker than other part of palpus. Antenna short, just a little longer than head. Scape cylindrical, wider than pedicel, twice as long as pedicel. Flagellum 13-segmented, flagellomeres gradually narrowing apically. Antenna yellow to light brown, scape always darker than pedicel and flagellomeres (Fig. 8C View Figure 8 ).

Thorax: In dry specimens general coloration yellow (Fig. 8C View Figure 8 ) to fulvous (Fig. 8A, B View Figure 8 ); 4 dark spots on presutural area of scutum and 7 spots on postsutural area, sizes of spots variable, especially lateral pair of spots on presutural area (Fig. 8B, C View Figure 8 ).

Legs: General coloration yellow, covered with yellowish setae (Fig. 8A View Figure 8 ). Femora without apical darkened area, apical part of tibiae brownish, with darker setae. Tarsomeres 1-3 each with narrow brown ring at tip. Tarsomeres 4 and 5 brown. Spurs on tarsomeres (2 in each segment), small but relatively easy to recognize for their darker coloration than setae.

Wing: As in Fig. 4D View Figure 4 . Wing with transverse dark lines in costal cell. Crossvein m-m present. Dark band from base of R2+3 extending to crossvein m-m. Dark band along crossveins r-m and m-cu pale.

Abdomen: Abdomen covered with comparatively long pale setae. Tergites 2-6 in both sexes, each with longitudinal narrow black line on lateral side, situated on basal 1/3-1/2 of each tergite in male (Fig. 8A, B View Figure 8 ) and 1/2-2/3 of each tergite in females. Sternite 2 with short black line positioned on lateral side in the middle between membranous area and posterior end of sternite 2. Sternites 3-6 with a little, wider than line on tergite (Fig. 8A, B View Figure 8 ). Sometimes line on sternite 6 indistinct or absent. Tergites and sternites 7 and 8 slightly darker than previous segments, dark yellow to brown.

Male terminalia: dark yellow to brown, always darkest part of abdomen (Fig. 8A View Figure 8 ). Tergite 9 almost straight at posterior margin (Fig. 5A, B View Figure 5 ). Gonocoxite without apical lobe 1.7-1.8 × longer than wide and 1.5-1.6 × longer than tergite 9 in lateral view (Fig. 5E, F View Figure 5 ). Apical lobe of gonocoxite not separated from gonocoxite, as long as 3/4 of width of gonocoxite, in lateral view (Fig. 5G, H View Figure 5 ). Posterior part of gonostylus wide, bearing 4 or 5 strong black spines (Fig. 5A, B, G, H View Figure 5 ). Interbase dilated apically, with two pointed parts; interbase with apical part 2.5-3 × as wide as basal part, in dorsal view (Fig. 5A-D View Figure 5 ). Shape of interbase in inner lateral view highly variable based on angle, directing postero-dorsally pointed at tip (Fig. 5G, H View Figure 5 ). Aedeagus short, twice as long as wide, tip rounded (Fig. 5I, J View Figure 5 ).

Female terminalia, ovipositor: General coloration dark yellow. Cercus curved upward (Fig. 6B View Figure 6 ). Genital fork cross-shaped, wider in 3/4 of its length (Figs 6D View Figure 6 , 7B View Figure 7 ). Lateral sclerite of genital plate small and narrow, 1/3 of length of genital fork (Fig. 7B View Figure 7 ). Genital opening Y-shaped, sclerotized area before genital fork relatively large, approximately as long as lateral sclerite (Fig. 7B View Figure 7 ).
