DESCRIPTION. ( Orneodes beinongdai after Yang, 1977; translated here from Chinese to English). “Body length about 3 mm. Wingspan about 10 mm, small size and light color. Body silver white. Labial palpus with outer side slightly light brown at base; basal two segments long cylindrical, covered with scales; terminal segment very short. Abdomen with segment II-V light brown except white apically. All other parts colored in white including antennae and legs etc. Forewing with a column of paired small brown spots only on costa not covered the lobes; other patches and spots indistinct but the boundary between white and light brown caused by cilia visible. Hindwing sacttered with some small brown dots. Patches and spots more obvious on the underside of wing; forewing with a column of small brown spots; outerlines of median fasciae and subterminal fasciae visible”.

MALE GENITALIA. Uncus tubular, terminal slightly wide; anterior margin slightly expanded laterally, with two small finger-shaped processes centrally. Gnathos strongly sclerotized, Y-shaped, arms equal to uncus in length. Tegumen simple, arched. Valva narrow; cucullus with a finger-shaped process, nearly reaching to gnathos. Anellus nearly quadrate at arms straight, about 1.5 times of uncus in length. Vinculum banded, about 2 times of uncus in length. Saccus nearly triangular. Aedeagus straight; length equal to sum of uncus and tegumen, width nearly equal to uncus; opening of ductus ejaculatorius at middle of aedeagus.

REMARKS. The male genitalia and habitus of both taxa are completing identical, therefore a new synonymy is proposed: Alucita beinongdai ( Yang, 1977) = Alucita ussurica Ustjuzhanin, 1999 , syn. n.

DISTRIBUTION. China ( Beijing), Russia ( Primorsky Krai).
