* Goniobranchus sinensis (Rudman, 1985) Figure 10D, E

Material examined.

Three specimens 20-55 mm, CP.

Ecology.

Among rocks and corals at offshore rocky pinnacles. Depth 9-22 m.

Distribution.

Across the Indo-Pacific including the Gulf of Oman ( Fatemi and Attaran 2015), India ( Sreeraj et al. 2012), Malaysia, Indonesia, China, and Japan ( Gosliner et al. 2008). Recorded from the Gulf waters of Thailand ( Chavanich et al. 2013).

Remarks.

Incorrectly identified as Goniobranchus trimarginatus (Winckworth, 1946) by Mehrotra and Scott (2016). Subsequent observations indicate that specimens from Koh Tao are Goniobranchus sinensis , with individuals being recorded with marginal and submarginal bands ranging from complete to broken.
