Indo-West Pacific, from East Africa and Madagascar to the Philippines and the Great Barrier Reef
Description
A small, pale chromodorid of the Chromodoris quadricolor colour group, described by Rudman in 1982 from the Great Barrier Reef and the Comoro Islands. The name means 'streaky', after the longitudinal black lines on its back.
Pale bluish-white mantle with black longitudinal lines of irregular width – typically a thin midline, a pair flanking the rhinophores and outer lines next to the border. The mantle edge has a watery-orange band into which tongue-like extensions of the bluish-white ground colour project. Gills and rhinophores are orange; the body sides are pale bluish-white with two black lines.
Similar species
Chromodoris elisabethina and C. quadricolor have a deeper blue ground colour and a solid orange or yellow border without the bluish 'tongues'; C. strigata is noticeably paler.
