Elliptera zipanguensis zipanguensis Alexander, 1924

Alexander, 1924: 559; Savchenko and Krivolutskaya, 1976: 113; Savchenko, 1983: 108.

General coloration of male dark brown to brownish black, female generally lighter than male. Body length of male 4.7-6.9 mm, that of female 5.3-6.7 mm. Wing length of male 6.9-9.6 mm, that of female 6.7-9.5 mm.

Head black, anterior part of vertex sparsely pruinose with grayish pubescense. Vertex between eyes broad, with a compressed median ridge immediately behind antennal bases. Antenna ( Fig. 4F ) dark brown to black, 16-segmented. Length of male antennae 2.0- 3.6 mm, female 2.1-2.6 mm. Male antenna, if bent backward, nearly reaches base of wing, that of female reaches middle of prescutum. Scape uniformly dark brown or with blackish apex. Pedicel uniformly dark brown or black. Flagellar segments covered with a dense gray pruinosity, oval, with distinct apical pedicels, covered with dense and short whitish pubescence in both sexes. Because female antenna is shorter than male, female flagellomeres as well as apical pedicels are shorter than in male. Apical segment cylindrical. Longest verticils approximately as long as respective segments. Rostrum dark brown to brownish black dorsally, light brown ventrally. Three basal palpal segments brownish black, distal segment light brown, tip same color as basal segments.

Thorax dark brown laterally, black dorsally. Pronotal scutum dark brown. Mesonotal prescutum shiny brownish black, the lateral margins paler, but also shiny brown, covered with grayish pruinosity. Mesonotal scutum dark brown, lateral angles light brown. Scutellum dark brown or black basally, redish brown apically. Specimens in ethanol have lateral and posterior margin light brown. Mediotergite dark brown with blackened posterior margin. Some specimens have lighter spot in the middle. Pleura brownish black with a longitudinal gray stripe across dorsal margin of sternopleura. Fronto-ventral angle of anepisternum, right behind frontal coxae distinctly blackened. Ventral part of katepisternum blackened. Dorsopleural membrane dark brown. Spiracles surrounded by black. Wing ( Fig. 4C ) distinctly and uniformly tinged with brown. No other darker spots, except elongate stigma, which is slightly darker than the rest surface of wing. Wing apex extended into an angle, round- ed. Vein Rs long and straight, and is very close to vein R. Cross-vein r beyond branching point of Rs, light, thus probably was overlooked by Savchenko and Krivolutskaya (1976, Fig. 46b). Discal cell open by the atrophy of the outer deflection of M 3. Basal deflection of CuA 1 at branching point of M. Both anal veins long and straight. Haltere brownish, the base of stem whitish. Frontal coxae brown frontally, whitish yellow posteriorly, middle and posterior coxae whitish yellow. Trochanters of all legs whitish yellow stained with blackish and with narrow dark brown rim at apex. Femur light brown with yellowish base and very narrow blackened rim at articulation with trochanter. Tibiae and tarsus brown. Male claw with a single, very slender subbasal spine. Spine is completely missing on female claw.

Abdomen dark brown, covered with grayish pruinosity. Abdominal tergites dark brown to black, sternites yellowish brown, subterminal segments blackish. Male genitalia ( Fig. 4E ) dark brown. Ninth tergite with distinct lateral lobes on posterior margin. Both gonostyles long and slen- der. Outer gonostylus dark brown with yellowish base, strongly sclerotised and hairless. Inner gonostylus fleshy and hairy. Ovipositor ( Fig. 4H ) with cercus yellow, short and very strongly upcurved. Tip hardened. Hypovalvae yellow, wide and blunt-apexed.

Flight period. lasts from April through middle of November in Korea.

Habitat. Adults are found at waterfalls, on wet rocks, along rocky streams and rivers in deciduous and mixed forests.

Distribution. Decsribed from Japan and Far East of Russia. Collected from the elevation 90-1800 m in Korea.
