Amphinemura verrucosa sp. n. (Figs. 12-15) Holotype çf , paratype 1 çf : Korea, Prov. Kanwon, Diamond Range, Hotel Go-song, 31. V. 1970 (No. 73). Length 8.5 mm, body 5 mm, fore-wing 6.5 mm long; expanse 14 mm. Unicolorous brown species, wings shghtly infuscated, veins brown, darkly bordered. An indistinct central patch on head a little hghter, reddish-brown. Surface of pronotum covered with fine hairs, a httle rugose, with silky shine. çf (Fig. 12-15) : Tergite 9 little elevated in middle, tiny spicules scattered all •over its posterior half. Tergite 10 bare, but with two strongly elevated tubercles beset with spicules, one on either side of epiproct, Epiproct moderately slender in •dorsal view, sides a httle concave, narrowed to indistinctly trilobate tip, a small bifid filament protruding from it. In lateral view, epiproct triangular, since ventral •spinuliferous sclerites elevated to form a high ventral keel, abruptly lowered at epiproct's narrow base. Ventral lobe of sternite 9 slender, widest at base. Subgenital plate elongate, distal portion bearing a keel and very high in lateral view. Sternite 10 reduced, paraprocts highly modified. Inner lobe rather wide, blade-like, middle lobe rod-like but with a wide base. Rod bent upward and sharply outwardly at tip, supporting membranous subanal lobe beset with numerous black spicules along its outer margin. Outer lobe of paraproct only partly visible in ventral view, its distal end being sharply bent upward and a httle anteriorly, supporting anterior edge of membarnous subanal lobe. In dorsal view, tip of outer paraproctal lobe visible as a dark stripe delimiting paraproct anteriorly. Cerci short, conical, one-segmented. 9 : Not known. Differential diagnosis — Belongs to a group of species characterized by the membranous subanal lobe fringed with marginal spines ; this group comprises A. decemceta OKAMOTO, A. flavostigma OKAMOTO, A. zonata OKAMOTO, A. megaloba (KAWAI) and possibly others, all from Japan. According to available descriptions and figures, A. megaloba is closest to the present species, which differs, however, in the presence of the terminal filament of the epiproct, the warts on tergite 10, and the absence of the small outer chitinous plate on the subanal lobe. None of the related species has the tips of the paraprocts bent so sharply outwards, almost anteriorly, hke in A. verrucosa. Amphinemura sp. (Fig. 16) • 1 $ : Korea, Prov. Kanwon, Diamond Range, Hotel Go-song, 29. V. 1970 (No. 54). The specimen resembles A. verrucosa sp. n. in size and coloration and has been taken together with the 2 çfçf of the former. However, the genitaha of this 9 differ so much from the pattern met among the closest relatives of A. verrucosa that conspecif ity seems improbable. Since a number of species from China is known only in the male sex, the female is not named. 9 (Fig. 16) : Subgenital plate on segment 8 with bisinuate posterior margin, lateral edges slightly longer than middle. Plate pigmented except a narrow median band failing to reach segment's anterior border. Sclerotized area narrowed a httle anteriorly, continuous with a sclerotized nipple projecting from posterior margin
