Kononenko, Vladimir S., Han, Hui-Lin, Yu, Alexej & V, Ато, 2010, A review of the Eastern Palaearctic genera Paragona Staudinger, 1892 and Paragabara Hampson, 1926 with description of two new species and a new genus (Lepidoptera, Noctuidae: Aventiinae, Hypeninae), Zootaxa 2679, pp. 51-68 : 66

Remmigabara , gen. n.

Type-species: Paragabara secunda Remm, 1983 , Entomologicheskoe obozrenie 62 (3): 596, fig. 7 ( Russia, Primorye terr., Tigrovoi).

Diagnosis. Wingspan 26–28 mm. Antennae of male filiform; labial palps much shorter than in Paragabara , directed obliquely upward, covered with dense yellow scales, their 3rd segment short; palps, head and collar covered with yellow-orange scales, forming characteristic “cap”; on head; M2 on hindwing developed; forewing characteristically concave from apex to mid part; wing ground colour magenta-brown, pattern formed by oblique pale lines shadowed with dark; hindwing uniform magenta-grey. In male genitalia, uncus straight, tegumen half the length of vinculum; scaphium sclerotized, transtilla long, juxta band-like; valva narrow with distinct, well separated elongated club-like cucullus; costa with acute extension in the middle, sacculus elongated, tapered, wall of sacculus with asymmetrical extensions. Aedeagus curved, vesica relatively short, with two short diverticula, without cornuti. In female genitalia, papillae anales short, anterior and posterior apophyses equal in length, antrum broad, cup-like, ductus bursae short, corpus bursae elongated, proximally extended.

Notes. The taxonomic placement of the Manchurian genus Remmigabara is unresolved and we tentatively associate Remmigabara with the subfamily Aventiinae (sensu Holloway 2009), due to the shape and pattern of fore wing, the presence of an orange-yellow “cup” on the vertex, the structure of the labial palps and the female genitalia. The male genitalia, however, has unique structures not found yet in Aventiinae. It may be that Remmigabara is allied to Britha Walker , [1866] 1865 (type species: Britha biguttata Walker , [1866] 1865 [ India to Taiwan and Australia]); at least Japanese Britha inambitiosa (Leech, 1900) ( Figs. 16 , 28 ) shows some similarity to Remmigabara in external characters and male genitalia. Monotypic, distributed in Manchurian subregion of the Palaearctic.
