Fig, 1. Adult of Eana incanana (Stephen sr),
nus and the short oblique dark brownish gray band from basal 114 of costa to middle of
wing (Fi g1.). The male genital iarae characterized by a slender uncus with spinulose basal
]obes, Iarge socij, blade-shape vdalvae, and a sacculus with a pointe dapex (Fi g2.). The fe-
male genjtal iarae characterized by enlarged papilla aenales (fiorico movoipuossitor) and a
dentat eband-shaped signum (Fi g3.) .Japanes especimens are smaller than European (wing
expanse 17-23 mm, of d1escriptio nofRazowski (2002)),
The species is distinguisha bflreom it scongeners of Japan by the median dark brownish
gray band and short band on basal 114 of costa of the forevving ,the blade-shape vdalva, and
the sacculus with a pointe dapex,
Remarks, The genus Eana Billberg ,1820 (tri Cbneepahsiin ii)s widely disnibuted in the
Holoarcti rcegion and North Africa ,with 38 described species (Brow n2,005) .In Japan two
species, E. argentana (Cler c1k7,59) and E. vetulana (Christ o1p8h8,1) ,have hithert boeen
recerded (Kawab e1,982; Jinbo ,2004-2007) .Both species were recorded from Japan by
Wtilsingham (1900 )for the firs ttime; however no specimen regarded as E, vetulana has
since been collected from Japan .Yasuda (1975 )recorded a specimen of E. sp, similar to E
atgentana from Hokkaido, but it is now recognized to be E, angentana,
