Ypsolopha japonica Moriuti : Zinchenko & Ponomarenko, 2008 : 58 ; Sohn et al. , 2010 : 32 . Type locality: Japan (Honsyû). Description. Adult ( Fig. 5 ): Wing expanse 24.0−25.0 mm. Forewing with R4 and R5 separated ( Fig. 56 ). Male genitalia ( Fig. 106 ): Uncus inconspicuous. Socius slender, dilated before apex, ending in point. Ventral plate of gnathos broadly tongue-shaped. Valva relatively slender, narrowed at base, arched along dorsal margin. Saccus 4/5 length of socius, dilated before apex. Anellus with width about 1/3 length of phallus, extremely broad and densely hairy on distal half. Phallus somewhat broad, slightly longer than valva, dilated at inception of ductus ejacuiatorius; coecum a quarter length of phallus; cornuti about half length of phallus, composed of two rows of microspines, each row with two or three larger thorns at apex. Material examined. 1 ♂ , 2 ♀♀, Neixiang County ( 33°02′ N , 113°50′ E ), Henan Province, 1350 m , 14−15.vii.1998 , coll. Houhun Li; 1 ♀, Laotudingzi, Huanren County ( 41°15′ N , 125°21′ E ), Liaoning Province, 8−9.viii.2009 , coll. Weichun Li & Jiayu Liu. Distribution. China (Gansu, Henan, Liaoning, Shanghai), Japan , Korea , Russia . Diagnosis. This species is similar to Y . amoenella ( Christoph) externally and internally, but can be distinguished by the separation of R4 and R 5 in the forewing ( Fig. 56 ), the specific cornuti composed of two rows of microspines that are about half length of the phallus in the male genitalia ( Fig. 106 ), and the intersegmental membrane between the papilla analis and the 8th abdominal segment longer than the abdomen in the female genitalia ( Fig. 156 ). In Y . amoenella ( Christoph) , R4 and R5 of the forewing are stalked ( Fig. 57 ), the male cornuti consist of two long thorns that are about 4/5 length of the phallus ( Fig. 107 ), and the female intersegmental membrane between the papilla analis and the 8th abdominal segment is just 3/5 length of the abdomen ( Fig. 157 ). Remarks. Byun & Bae (2001) recorded one male specimen from Gwangleung, Korea , but did not provide the structure of male genitalia. The male genitalia are described for the first time in this paper.
