Description
Reaches about 45 mm in length. Ground colour is highly variable, ranging through green, reddish purple and white. The dorsum bears blotches of contrasting colour and a longitudinal midline ridge from which several lateral ridges run transversely; where these lateral ridges reach the mantle edge, the margin extends outward as a series of lobes. Rhinophores and gills are sprinkled with fine white dots, distinguishing this species from the otherwise similar Miamira flavicostata.Distribution
Indian Ocean to the western and central Pacific. Records include Tanzania, the Red Sea, Maldives, Thailand, Australia, the Solomon Islands, Papua New Guinea, Indonesia, Malaysia, the Philippines, Japan, the Marshall Islands and Hawaii. The type locality is Anyer Bay (Anjer-baai), west Java, Sunda Strait, Indonesia.Etymology
The specific epithet sinuata is the Latin for "sinuated" or "wavy" (from sinuare, "to bend or curve"), referring to the scalloped mantle margin. Van Hasselt's diagnosis specifies "pallii margine sinuato, sinubus 6 aut 7" — a mantle margin with six or seven sinuses.Remarks
Originally described as Doris sinuata by van Hasselt in his Java mollusc letter (Bulletin des Sciences Naturelles et de Géologie, vol. 1: 239, 1824), based on material from Anyer Bay in the Sunda Strait. Van Hasselt regarded the species as "rarissima" (very rare) and noted a distinctive tri-cusped dorsal keel and blue ocelli on a green ground. Subsequently transferred to the genus Miamira Bergh, 1874.References
