Bibliographic data :
The body shape is elongate and convex. The body is widest in the branchial region. The head is rounded anteriorly and oral tentacles are relatively short and cylindrical with a rounded apex. The posterior end of the foot is sharply tapered.
The, non-retractile, perfoliate rhinophores are relatively short with 7–8 lamellae and have an elongate tip. The extrarhinophoral appendages are relatively short, thin and have a curved apex.
The gill consists of three bipinnate branches. The extra-branchial appendages are curved, and slightly longer than the extra-rhinophoral appendages.
The extra-rhinophoral and extra-branchial appendages are creamy white with a few brown spots.
The bases of the oral tentacles are brown with white dots and the apices are white.
This species is similar to Trapania brunnea from Australia T. dalva from Florida and T. goddardi from Mexico
Etymology : The specific name euryeia is from the Greek word meaning ‘widespread' to describe the wide geographic range of this species.
