Reasoning recorded at review

• •Elongate Elysia body with paired rolled rhinophores and broad closed parapodia
• •Translucent whitish ground created by dense opaque-white pigment
• •Numerous yellow-orange spots, several arranged into short longitudinal rows
• •Distinct pale neck patch behind the rhinophores
• •Yellow-orange pigment at the rhinophore apices and along parts of the parapodial edge

Alternatives considered

• Elysia asbecki

  Why plausible: The overall white, orange-spotted, row-patterned morph and pale neck patch closely match the original description

  Comparison: The characteristic dark-then-yellow rhinophore rings, tiny black parapodial dots and reddish patches at the parapodial bases and tail are not all resolved in this frame

• An undescribed white-and-orange Elysia

  Why plausible: The Indo-West Pacific genus contains substantial unresolved and pseudocryptic diversity

  Comparison: A second view, host alga, preserved anatomy and DNA would test whether the missing E. asbecki colour elements are genuinely absent

• Elysia trisinuata

  Why plausible: Can be pale green-white with minute orange spots and white parapodial papillae

  Comparison: E. trisinuata is expected to show a green digestive network, three-fold undulating parapodia and blunt greyish rhinophore tips rather than the strongly white striped-spotted appearance here
