Mycomya cissa sp. n. , male hypopygium. A–B tergal and sternal views, C tergal combs, posterior view with both outer and inner combs visible, twice enlarged, D tergal lateral appendage, twice enlarged, E gonostylus, twice enlarged, F tergite 8. Scale 0.2 mm. Description. ♂. Head. Palp brownish, other mouthparts and face yellowish, posterior parts of head brownish. Antenna brownish, scape, pedicel and base of 1st flagellomere yellow. Length of 1st flagellomere about 4x , 2nd flagellomere 2.5x, its width. Thorax. Pronotum yellow, with 3–4 long setae. Scutum yellowish with 3 indistinct brownish longitudinal stripes. Anepisternum yellow. Preepisternum yellow, ventral half brownish. Scutellum brownish, with 4 long setae. Laterotergite brownish. Mediotergite brownish, bare. Wing. Length 3.6–3.8 mm . Wing hyaline. Sc ending in R1 proximad of middle of small cell, Sc1 missing. Apical part of Sc bearing no small setae. Small cell shorter than its width. Cu fork slightly distal to M fork. M ratios: 0.75–0.90, 1.03–1.21. Cu ratios: 0.86–1.00, 1.37–1.56. Small setae: M petiole: 0; M1: 0; M2: 0; Cu petiole: 0; Cu1: 0; Cu2: 0. Halter apically brownish. Legs. Coxae and femora yellow, tibiae and tarsi brownish to brown. Coxa 2 without spur. Leg ratios: bt1:t1 = 0.79–0.81, bt2:t2 = 0.69–0.70, bt3:t3 = 0.60. Abdomen. Tergites brownish, sternites slightly paler. Hypopygium. Figs.1 A–F: yellowish. Tergal part with 1 very wide outer comb of short spines. Some spines also between wide outer comb and 2 inner combs ( Fig.1 C). Inner combs wide, each with 12–14 spines. Only lateral parts of base of outer comb with some setae, its median part bare. Dark inner spur of tergal part apically blunt. Tergal lateral appendage long, relatively slender, about 4x as long as wide, setose, with some slightly flattened, relatively short (slightly longer than width of tergal lateral appendage) subapical setae on inner side ( Fig. 1 D; also Fig. 1 A, on both sides of outer comb). Sternal submedian filament ( Fig. 1 B, narrow basal extensions of deeply bilobed sternal synsclerite along medial side of its both lobes) relatively short, hardly reaching apex of sternal synsclerites, slightly curved. Gonostylus tapering towards its apex, with 4 subapical teeth, 1 strong apical seta, and relatively large membranous lobe only slightly shorter than main branch of gonostylus ( Fig. 1 E). Aedeagus long, slender, with 2 very long slender lateral appendages extending slightly beyond its apex ( Fig. 1 B, mid-upper part). Discussion. Mycomya cissa differs readily from the other species of the subgenus Cesamya in the unique shape and structure of the tergal combs formed by stronger spines ( Figs. 1 A, 1C) than in the other species. Other diagnostic features include tergal lateral appendage ( Fig. 1 D) lacking the curved flattened setae and sternal submedian filament not extending beyond the apex of the sternal synclerite ( Fig. 1 B). Etymology. The species name is a noun in apposition and refers to the green magpie (genus Cissa F. Boie).
