Aedeagus . Median lobe ( Figs. 7 F–G) narrowly ovate and widest in basal fourth, apical process constricted basally and convergent at apex in ventral aspect; internal sac elongate. Apical lobe of paramerites ( Fig. 7 H) with four setae; a-seta longest, c- and d-setae shorter than b-seta, close together and positioned apically. Spermatheca . Bursa globular apically, with small umbilicus; duct simply coiled ( Fig. 7 I). Type material. Holotype , , labeled as follows: ‘ Korea 1981 Vaudo A. Szeptycki ; HOLOTYPE Liogluta pyonganica sp. n.
