Exogenous sperm duct narrow, running from junction of vaginal duct and bursa copulatrix to fertilisation chamber within female gland mass. Small, rounded, exogenous sperm sac opening about one-third of the way along exogenous sperm duct. From ovotestis, spermoviduct expands into ampullar region, distended with endogenous sperm. Inside female gland mass, spermoviduct divides into two short ducts; the oviduct, opening into the fertilisation chamber; the sperm duct, opening into relatively short prostate gland. Vas deferens joins prostate gland to bulbous penial sac.

the body is opaque white except for a pair of translucent bands on the head running forward from beneath the anterior lateral papilla on each side. There are some large orange patches on the head, some of which are irregularly edged in brownish purple. An orange band, mottled with purple and white, runs back between the rhinophores expanding to form large patch over much of the mantle, anterior to the gills. An orange band, irregularly bordered with purple, runs along each side of the body, beneath the mantle, to the tip of the posterior foot, which has brownish purple patches. The lateral papillae are white with an orange tip and subapical purple band. The rhinophores have a translucent whitish base, an orange-brown tip and the rest is mottled with patches of translucent purple, pigmented purple, and orange-brown, with two or three white spots down the anterior face. The gills are translucent with brown and white pigmentation. In the Red Sea specimen, the orange-brown bands described for the Tanzanian specimen are replaced with translucent colourless bands, except along the leading edge of the head, and the purple patches on the body are reduced to the anterior head and the posterior tip of the foot. Scattered over the body are small rounded orange spots. Small purple spots are also present on the lateral papillae, rhinophores and posterior tip of the foot.
