Thuridilla
cf. vatae (Risbec. 1928)
 
Thuridilla cf. vatae
Maximum size: about 25 mm.

Identification:  This species has a cloudy-blue body variably decorated with diffuse black and yellow patches. The rhinophores are bluish-cream with brick-red tips and the parapodia may have yellow/orange marginal lines.

Natural history:  Thuridilla cf. vatae is known from four animals. Three were found at a depth of 2-3 m (3-10 ft) in a mixed habitat. The other was found at 13 m (44 ft) on dead coral.

Distribution:  Maui: Thuridilla vatae is widely distributed in the Indo-Pacific.

Taxonomic notes:  This species may be T. vatae. However, the bluer background and yellow/orange marginal lines on the parapodia suggest some degree of genetic isolation from populations found elsewhere in the Indo-Pacific. It was first found in Hawaii outside the Ko'ie'ie Fishpond, North Kihei, Maui by Tara Branham on Nov. 23, 2018.
