Lecithocera daebuensis Park & Lee, 1999

[Japanese name: Debudou-hosoba-higenaga-kibaga]

( Figs 1c , 2b , 3b , 4b )

Lecithocera daebuensis Park & Lee, 1999: 121 ; Sakamaki, 2013: 222.

Type locality: Daebu Is., Korea , Type specimen in KNA .

Diagnosis. The species is distinguished from its allies by the following characteristics: forewing with two obscure discal spots; ground color of forewing dark grey; cucullus of the male genitalia broad, 2/3 times as wide as long. The species is superficially very similar to L. metacausta Meyrick, 1910 but it can be distinguished by the following characteristics: forewing more greyish with a pair of small discal spots; male genitalia with a bundle of long setae between basal parts, and the valva with a round apex. It is also very similar to L. goniometra Meyrick, 1929 in genitalia, but it is distinguished by the wingspan smaller than the latter, antenna yellow, the single outer discal stigma of forewing. It is also similar to L. shanpinensis Park, 1999 in genitalia, from which it differs by the wingspan larger than the latter, and forewing vein R3 from basal 1/3.

Description. See Park & Lee (1999) for detailed description of the adults and genitalia. Female genitalia unknown.
