Chromodoris lineolata from Hong Kong

January 27, 2002
From: Bill Rudman & Brian Darvell

Here is some information and photos on Chromodoris lineolata from Brian Darvell's Hong Kong collections.

One of a number of very similarly coloured species found in the Indo-West Pacific (Rudman 1982) two of which are known to occur in Hong Kong. Chromodoris lineolata can best be described as black with narrow heavily pigmented longitudinal white lines. The edge of the mantle has an orange border and usually the inside edge of the orange border is alongside a black rather than a white line. Both the gills and the rhinophores are blackish, often with a reddish tinge, and spotted with white.
It is very similar in colour to C. striatella, but the distinctly pigmented white lines and the black line alongside the orange border are characteristic of the species. It grows to 50 mm in length.
