Description
The Socotra specimen is an almost perfect replica of the type specimen, with two incomplete median circles of small tubercles. First lateral encircling band of tubercles composed of small tubercles followed by row of single isolated tubercles and narrow black line before pink margin; long black rhinophores (Fig. 21A). Large fused oral tentacles tinged with black in life; pigment still remains on Madagascar specimens 20 years later (Fig. 21B).
Remarks
Although easily recognized, Phyllidiella meandrina is not a common species in the western Indian Ocean; it has not been recorded from the Maldives (contrary to my statement in Yonow et al. 2002[1]: 864). Eliot’s (1904) species recorded as Phyllidiella nobilis from East Africa is here identified as Phyllidiella meandrina: his description and illustrations of the outer two to three rows of tubercles are typical of Phyllidiella meandrina.
