Description
Body 3–10 mm long, elongate and convex, lacking a notal margin. Widest at the branchial region. Oral tentacles are relatively short and cylindrical with rounded apices. Rhinophores are relatively short with 7–8 lamellae and have an elongate tip. Extra-rhinophoral appendages are relatively short, thin and curved. Extra-branchial appendages are curved and slightly longer than the extra-rhinophoral appendages. Gill of three bipinnate branches.The body is pale yellow with brown patches showing white or pale yellow punctuated spots through the brown. The bases of the oral tentacles are brown with white dots, and the apices are white. Extra-rhinophoral and extra-branchial appendages are creamy white with a few brown spots. Rhinophores and gill leaves are the same pale yellow as the body with random brown blotches.
Distribution
The most widespread Trapania species, ranging from Reunion to Papua New Guinea, Indonesia (Sulawesi, Bali), Okinawa, Marshall Islands, Midway Atoll and Hawaii.Etymology
Verbatim from the original description (Gosliner & Fahey, 2008, p.77):The specific name euryeia is from the Greek word meaning 'widespread' to describe the wide geographic range of this species.
Remarks
Described as one of 16 new Indo-Pacific Trapania species in Gosliner, T.M. & Fahey, S.J. 2008 Zoological Journal of the Linnean Society 152: 53-111. Externally most closely resembles T. brunnea from Australia, T. dalva from Florida and T. goddardi from Mexico, but T. euryeia "has minute yellow, punctuated dorsal spots that are absent in T. brunnea" and a continuous white mid-notum band rather than the long lateral extensions found in T. brunnea (p.77-78). Japanese animals figured by Ono 1999 and Nakano 2004 as T. brunnea are referred here as misidentifications (p.75).References
