Metanomeuta fulvicrinis Meyrick, 1935

( Figs 3 , 15 , 22–25 )

Material examined. 1 ♂, Russia, Primorskii Krai , Ussuriiskii district, 20 km SE of Ussuriisk, Gornotajezhnoe village, 43°41’44” N, 132°09’26” E, 05.vii 1995, (leg. M. Ponomarenko), GS 343 AT, FSCB .

Diagnosis. M. fulvicrinis is similar to M. yuexiensis and M. spinisparsula in the male genitalia by relatively wide socius tapering towards pointed apex, which is curved ventrally and bearing small thorn, valva wide in basal part, sacculus as sclerotised thorned plate and aedeagus with cornuti as spines packed in bunches. M. fulvicrinis differs from related species by male genitalia with socius wider in basal part and smoothly tapering towards the pointed apex, valva with large ventro-basal lobe rounded at apex and with sacculus bearing strong thorns on the relatively wide band-like sclerotisation, and aedeagus sinuous in basal 2/3 and curved at distal 1/3, with spiny cornuti packed into two bunches, about 1/5 of aedeagus length ( Figs 22–25 ).

Comparative morphological notes. Generally, specimen collected in the Russian Far East and identified as M. fulvicrinis Meyrick , is similar to related species by characters of external morphology. However, its wingspan 12.5 mm, which is corresponding to smaller parameters of wingspan indicated for M. fulvicrinis from China and similar to that in M. yuexiensis . Labial palpus lighter, first segment light brown, second and third segments greyish brown on outer side and lighter on inner side ( Fig. 15 ). Tegulae and thorax brown, that lighter than in related species. Forewing greyish brown, with indistinct lightened spots: large one beyond basal 1/3 on dorsal half and smaller ones at 4/5 of costal margin and at apex ( Fig. 3 ), that is similar to forewing illustrated for lectotype of M. zonoceros in Clarke (1965: plate 173, fig. 2) and for some specimens collected in China and identified as M. fulvicrinis .

Host plant. Unknown.

Distribution. Russia (south of Far East: Primorskii Krai), first record; South Korea; China ( Henan, Sichuan, Anhui, Hubei, Zhejiang, Jiangxi, Hunan, Guizhou, Fujian, Guangxi); Japan (Honshu, Shikoku, Kyushu).
