Goniobranchus tumuliferus is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.[2]

Distribution

This species was described from Slut Island, Haitan Straits, China. Additional specimens were found by Collingwood at Labuan, Borneo.[1] It has been reported from Thailand, Singapore, Japan, Hong Kong,[3] Indonesia, Fiji and New Caledonia.[4]

Description

Chromodoris tumuliferus is a chromodorid nudibranch with a translucent white mantle and large, carmine-red spots. There is a submarginal line at edge of the mantle which is yellow, either continuous or broken into yellow blotches, with a translucent or white extreme edge. In this outer margin there may be more red blotches or an almost continuous red margin. The wide distribution and variable colour pattern suggest a possible species complex.[4][5] This species was transferred from Chromodoris to Goniobranchus on molecular (DNA) evidence.[6] It is very similar in appearance to Goniobranchus kitae but that species has small white spots on the gills and rhinophores.[7]
