Description. 3. Head. Palp and other mouthparts brownish, face light brownish, posterior parts of head brown. Antenna brownish, scape, pedicel and base of 1 st flagellomere yellow. Length of 1 st flagellomere about 2.5 x, 2 nd flagellomere 1.5 x, its width. Thorax. Pronotum yellow, with 3–4 long setae. Scutum brown. Anepisternum yellowish. Preepisternum brownish. Scutellum brown, with 4 long setae. Laterotergite brownish. Mediotergite brownish, bare. Wing. Length 4.6 mm. Wing hyaline, small cell distinctly and wing apex slightly infuscate. Sc ending in C distad of middle of small cell, Sc 2 ending in R 1 near middle of small cell. Apical part of Sc bearing 8–9 small setae. Small cell about 2 x as long as wide. Cu fork proximal to M fork. M ratios: 1.04, 1.44. Cu ratios: 0.65, 1.00. Small setae: M petiole: 0; M 1: +; M 2: +; Cu petiole: 0; Cu 1: 1; Cu 2: +. Halter pale yellowish. Legs. Coxae and femora yellow, tibiae and tarsi brownish to brown. Coxa 2 without spur. Leg ratios: bt 1:t 1 = 0.80, bt 2:t 2 =?, bt 3:t 3 = 0.63. Abdomen. Tergites 1 brown, 2–4 brown, with large yellow anterolateral spots, 6–7 brown. Sternites 1–5 yellow, with narrow brownish posterior margins, 6–7 brownish. Hypopygium. Figs. 7View FIGURE 7 A –D, yellow. Sternal lateral appendage comparatively short, wide, basally widest, apically rounded ( Fig. 7View FIGURE 7 B). Sternal submedian filament long, apically narrow and slightly curved ( Figs. 7View FIGURE 7 A –B). Aedeagus apically rounded in lateral view ( Fig. 7View FIGURE 7 C). Female. Wing length 4.5 mm. Sc ending in R 1, Sc 1 almost or totally missing. Cu fork slightly distal to M fork. Thorax yellow, scutum with brown median longitudinal stripe, scutellum, ventral half of preepisternum, laterotergite and mediotergite yellowish. Abdomen yellowish, anterolateral corners of tergites yellow. Leg ratios: bt 1:t 1 = 0.79, bt 2:t 2 = 0.68, bt 3:t 3 = 0.60. Terminalia yellow. The Indian Ƥ (which may represent another closely related species) has darker thorax with only the pronotum, anepisternum, and dorsal half of preepisternum yellow.

Discussion. Mycomya panthera  is a large species and has a large hypopygium compared to the other Himalayan species of the subgenus Cymomya  . The shapes of the sternal lateral appendage and sternal submedian filament are diagnostic. The sternal submedian filaments of M. panthera  are slightly shorter than the sternal lateral appendages ( Fig. 7View FIGURE 7 A –B), which are wide, apically rounded of the shape of a reversed U ( Fig. 7View FIGURE 7 B) and the apex of the aedeagus is about 2 x as wide as its subapical narrowest part in the lateral view ( Fig. 7View FIGURE 7 C), whereas in the other Himalayan species the apex is only slightly wider than its subapical part ( Figs. 4View FIGURE 4 C, 5 D, 6 C).

Etymology. The species name is a noun in apposition and refers to the big Asian members of the cat family.
