Description
A small phyllidiid 4-14 mm long, oval-elongate in shape, with blue and black stripes on the dorsum. Three median, longitudinal, low, granular blue ridges extend to the vicinity of the anus. On either side of the ridges run four narrow black stripes in total. The mantle perimeter is also blue and granulose with a few tiny black spots. Notal tubercles occur in the blue areas, are tiny and rounded, and are most numerous around the margins. The anal opening is black. The rhinophores are black with grey bases, each clavus bearing 7-10 lamellae (10-14 mm specimens). Ventrally, the hyponotum is white with black spots. The gills are dark grey. The foot is uniformly grey, and the oral tentacles are black dorsally and ventrolaterally, grey midventrally.Distribution
Northern Papua New Guinea (Madang) and southern Thailand. Type locality: Phi Phi Island, southern Thailand (10 m).Etymology
Verbatim from the original description (Brunckhorst, 1993, p.72):This species is named for my mother, Anne.
Remarks
Described as a new species in the Brunckhorst 1993 revision of the Phyllidiidae Records of the Australian Museum, Supplement 16: 1-107. Phyllidiopsis striata also has dorsal ridges, but they are white, with a white mantle margin (blue in this species) and lemon yellow rhinophores. Phyllidiopsis sphingis shares blue pigmentation, but the blue is confined to the margins, and its median ridges are granulose rather than blue.References
