REMARKS

Frenulina sanguinolenta is a common and widely distributed species in the Pacific region and has been recorded by many authors (see Bitner 2006 a, b, 2008, 2009, 2010, 2014). Apart from a contentious occurrence of a single specimen from the eastern Mediterranean ( Taddei Ruggiero 2000; Logan et al. 2004) the species appears to be otherwise restricted to the Pacific Ocean . Cooper (1973a) described Frenulina cruenta from the coast of Mozambique and Somalia in the western Indian Ocean and distinguished it from F. sanguinolenta by its greater size, more intense colour banding and conjunct deltidial plates, in contrast to the disjunct deltidial plates usually seen in F. sanguinolenta . Here we record F. sanguinolenta for the first time from the Indian Ocean and also note the presence of several specimens attached to corals from shallow reefs of Toleara, South-West Madagascar collected by Bernard Thomassin in 1975 and presented to A. Logan for study.
