Description. ♂. Head. Palp brownish, other mouthparts yellowish, face yellow, posterior parts of head brownish. Antenna brownish, scape, pedicel and base of 1 st flagellomere yellow. Length of 1 st flagellomere about 3.5 x, 2 nd flagellomere 2 x, its width. Thorax. Pronotum yellow, with 2 long setae. Scutum yellow to yellowish with 3 brown longitudinal, posteriorly fused stripes. Anepisternum yellowish. Preepisternum yellow, ventral part light brownish. Scutellum yellowish, with 4 long setae. Laterotergite brownish. Mediotergite brownish, bare. Wing. Length 3.3 –5.0 mm. Wing hyaline. Sc ending in R 1 near or proximad of middle of small cell, Sc 1 missing. Apical part of Sc bearing 0–1 small setae. Small cell 1–1.5 x as long as wide. Cu fork distinctly distal to M fork. M ratios: 1.00– 1.09, 1.38–1.50. Cu ratios: 0.93–1.14, 1.56–2.08. Small setae: M petiole: 0; M 1: 0–7; M 2: 0–4; Cu petiole: 0– 1; Cu 1: 0–12; Cu 2: 0–7. Halter pale yellowish. Legs. Coxae yellow, femora yellow, tibiae and tarsi brownish to brown. Coxa 2 without spur. Leg ratios: bt 1:t 1 = 0.82–0.87, bt 2:t 2 = 0.65–0.73, bt 3:t 3 = 0.58–0.60. Abdomen. Tergites brownish, sternites brownish with yellowish posterior margins. Hypopygium. Figs. 12View FIGURE 12 A –G: yellowish. Tergal part with 2 pairs of combs, outer combs very narrow and their base deeply bilobed ( Fig. 12View FIGURE 12 A). Tergal lateral appendage setose, wide, basally more than 2 x as wide as its slender apical part; apical part of tergal lateral appendage narrow, strongly curved, with some flattened, curved apical setae ( Fig. 12View FIGURE 12 D). Sternal submedian filament relatively short, slightly curved, extending slightly beyond apex of sternal synsclerite. Gonostylus more than 4 x as long as wide, apically slightly wider than basally, with 3–4 subapical teeth and long, strong, slender spur with 1 apical tooth, and membranous lateral lobe about ½ of length of main branch of gonotylus ( Fig. 12View FIGURE 12 E). Aedeagus with 2 lateral appendages extending slightly beyond its apex ( Fig. 12View FIGURE 12 F). Female. Wing length 4.7 mm. Thorax yellow, posterior part of mediotergite brownish. Abdomen brownish. Veins Sc, M and Cu bare.

Discussion. The male hypopygium of M. naja  is generally quite similar to Chinese M. vaisaneni  Wu & Yang, 1994, but differs from it by having a strong spur on the gonostylus ( Fig. 12View FIGURE 12 E), similar to that of the Nearctic M. sublittoralis Shaw, 1941  . Mycomya sublittoralis  is otherwise very different from M. naja  , e.g. its tergal combs are much wider than in M. naja  ( Fig. 12View FIGURE 12 A) and the setosity of the tergal lateral appendage is not restricted only to the basal and apical parts (Väisänen 1984: figs. 1051–1056).

Etymology. The species name is a noun in apposition and refers to Naja  Laurenti, the genus for the cobras, a group of venomous elapid snakes.
