Description
Body slug-like, with the dorsum not differentiated from the sides; rhinophores entire (not perfoliate), retractile into a cavity protected by a small valve; the gill is non-retractile and protected by a dorsal velum. Labial armature absent. The skin is very rough — "very rugose and of a rigid coriaceous texture" — and carries abundant spicules. The alcohol-preserved type measured 18 mm long, 12 mm wide and 11 mm high. In life the animal is uniformly lemon yellow, strongest on the dorsum, with a fine mantle-margin border (bluish-grey within, black outside); the rhinophore lamellae and the edges of the gill leaves are brownish. The dorsum slopes down both anteriorly and posteriorly; in front it forms a large frontal veil; the non-retractile gill consists of about seven leaves protected by a notched dorsal velum.Distribution
Type locality: Rarotonga, Cook Islands. Subsequently re-described from a Palau specimen and now known to range across the tropical Indo-West Pacific.Etymology
The specific epithet citrina is the feminine form of Latin citrinus ("citron-coloured, lemon-yellow"), referring to the uniform lemon-yellow colour of the living animal. The genus name Notodoris is a Latinised compound of Greek noton ("back") and Doris, alluding to the diagnostic feature that the gill is non-retractile and is protected by a special dorsal velum.Remarks
The species was described as the type species of the new genus Notodoris. It has subsequently moved between Aegires and Notodoris and is currently placed in Notodoris (Aegiridae).References
