Arbela? dea Swinhoe, 1890 , Trans. ent. Soc. London, 1890: 199.

Type locality: Rangoon [ Myanmar] .

Type material. Holotype (male) in NHMUK, examined.

Material examined. Holotype, male, Rng [Rangoon], 5/[18]86 ( NHMUK, slide Cossidae # 259).

Redescription. Male. Length of fore wing 10 mm. Antenna bipectinate, setae 2.5‒3 times longer than antenna rod diameter. Body gracile. Fore wing brown, with poorly expressed pattern of black strokes postdiscally and submarginally, border very thin, black. Fringe light-brown, unicolorous. Hind wing dark-brown with light-brown anal edge. Fringe light-brown, unicolorous.

Genitalia. Uncus long, with parallel lateral sides, slightly extended apically, with triangle notch on apex; gnathos arms thin; subscaphium spindle-like, elongated; valve semicircular, saccular edge strongly sclerotized, lamellar, small mastoid harpe and fold-shaped harpe on saccular third of inner surface of valve; juxta wide, lamellar; saccus reduced; phallus shorter than valve, almost straight, basally swollen, apically narrowing, hooky cornutus closer to apex.

Female unknown.

Diagnosis. Judging from the characteristic features of the male genitalia, namely – the poorly extended uncus and the strongly swollen basal end of the phallus, the species belongs to the genus, recently described by us – Marcopoloia Yakovlev & Zolotuhin, 2021 , which leads to the establishment of a new combination: Marcopoloia dea ( Swinhoe, 1890) comb. n. Currently, the genus includes 6 species, distributed in southeastern Asia ( Yakovlev & Zolotuhin, 2021b). Externally, M. dea is most close to M. leloi Yakovlev & Zolotuhin, 2021 (type locality: C. Vietnam, Gia Lai Prov., Kon Ka Kinh NP), from which it differs in the slightly extended apex of the uncus and in the less expressed harpe on the saccular edge of the valve.

Distribution. Myanmar.
