Holotype ♂ (Illinois Natural History Survey), Jirisan , Mamyanggun , Songjeon-li , Mansu-sa , [Republic of] Korea Material examined. Republic of Korea : Jirisan , Hamyang-gun , Songjeon-li , Macheon-Myeon , 700 m , 35° 20.93’ N , 127° 38.50’ E , 27 July-16 August 2004 , P. Tripotin , Malaise trap on small stream, 4♂ , 2♀ ( USNM ). Female. Forewing length 26 mm . Subgenital plate short and triangular, projecting over base of sternum 9 and bearing a small triangular notch ( Fig. 11 ). Vagina membranous except for a small sclerite at spermatheca base ( Fig.12 ); outline somewhat rectangular but with anterolateral margins slightly projecting. Spermathecal stalk forming a half-coil; spermatheca an elongate, balloon-like structure. Figs. 11-12. Kamimuria zwicki female structures. 11. Terminalia, ventral. 12. Vagina and spermatheca, ventral. Egg. Outline of body oval, length (including collar) ca. 420 µm , width ca. 347 µm ( Fig. 13 ). Collar stalked with flanged and incised rim, collar length ca. 38 µm , collar diameter across rim ca. 77 µm ( Figs. 14-15 ); anchor mushroom shaped and covered with small globular structures imbedded in follicle cell impressions ( Fig. 17 ). Chorionic surface covered throughout with hexagonal follicle cell impressions ( Figs. 13, 16 ); walls of follicle cell impressions smooth and raised above pitted floors ( Figs. 14-16 ). Micropyles form an irregular subequatorial row; each orifice surrounded by rosette of follicle cell impressions ( Fig. 18 ). Comments. The egg of this species is generally similar to that of K. lyubaretzi Teslenko ( Teslenko 2006 ) but the chorionic surface of that species is coarsely and regularly pitted throughout and the follicle cell impression walls are not elevated. In addition, the anchor of K. lyubaretzi is flattened and the female subgenital plate has no notch. Stark & Sivec (2008a) commented on the similarity of internal male genitalia for these probable sister species.
