Mantle wide, covering an entire foot. Dorsal surface of mantle covered by caryophyllidia and ornamented by minute black or white specks. White specks arranged along the mantle edge. Gills seven to ten in number, tripinnate, arranged in a gill circle surrounding anus on dorsal surface of mantle.
GenBank accession number. OK143201.
Distribution. Korea, Hong Kong, Japan, Australia, Hawaii, Malaysia, Philippines (Indo-Pacific), Tanzania (Africa).
Remarks. Rostanga species are characterized by having reddish-orange body color and caryophyllidia, specialized sensory tubercles on the dorsal surface of mantle. R. bifurcata and R. orientalis are commonly found in the northwestern Pacific and morphologically very similar, but distinguished by the lamellae in rhinophores. R. bifurcata has horizontally arranged lamellae in rhinophoral clubs, while R. orientalis has rhinophoral lamellae that are vertically arranged.
