Description
The dorsum is keeled with transverse ribs. Unlike most other Miamira, the species lacks frontal and caudal veils and the lamellate ventral lateral mantle lobes; the foot is somewhat wider. In the alcohol-preserved type (4 cm long), the mantle margin projects up to 10.5 mm beyond the body sides; a knobby median ridge runs along the front half of the dorsum and at least two pairs of stout transverse ridges run out to the mantle margin; another transverse pair lies in front of the gill area. The rhinophore clubs bear about 25 leaves; the gill is tripinnate (sometimes nearly quadripinnate) with about 12 leaves. The dorsal ground colour in life is a mixture of leek-green, blue and grey, with brown ocelli with bluish-green pupils and whitish tubercles. The mantle is bordered with yellowish, and below it is verdigris with whitish spots throughout. Rhinophores brown with white-spotted lamellae; mouth and oral tentacles verdigris; gill yellowish. Flanks purplish-brown with blue spots; foot leek-green.Distribution
Type locality: Tahiti (French Polynesia). A large specimen from Zamboanga, Mindanao (Philippines) was used for anatomical re-description, and the species is treated as a widespread Indo-West Pacific element.Etymology
The specific epithet miamirana is the feminine form of an adjective formed from the genus name Miamira plus the Latin adjectival suffix -anus, -a, -um, meaning "Miamira-like". The species was originally placed in a new genus Orodoris and named for its external similarity to Miamira; when Orodoris was later synonymised with Miamira, the epithet remained in place, producing the present unusual genus-and-epithet repetition Miamira miamirana.Remarks
Original combination: Orodoris miamirana. Orodoris was subsequently placed in synonymy with Miamira; the parentheses in the author citation reflect this generic transfer.References
