* Carminodoris cf. bifurcata Baba, 1993 Figure 12D

Material examined.

Two specimens 9-17 mm, HF.

Ecology.

Among rubble in shallow coral reef habitats. Depth 3-8 m.

Distribution.

Carminodoris bifurcata is recorded across the Indo-Pacific including from Mozambique ( Tibiriçá et al. 2017), the Red Sea (Yonow 2008), Korea (Koh 2006), the Philippines, Japan, and Hawaii (Gosliner and Fahey 2011) and Carminodoris flammea is recorded from Indonesia (Gosliner and Fahey 2011). Neither species has been previously recorded from Thai waters.

Remarks.

Specimens from Koh Tao resemble both Carminodoris bifurcata Baba 1993 and Carminodoris flammea (Gosliner and Fahey 2011). They differ from the descriptions of the former by lacking any black spots on the dorsum and having a brown rather than grey ground colour and they differ from the latter in having brown rather than grey gill leaves, with white tips, and a tan median colouration instead of the bright red for which the species is named. A very similar looking specimen from Vietnam was identified as Hoplodoris bifurcata by Martynov and Korshunova (2012: pl. 31E). However, see discussions regarding Carminodoris pustulata (Abraham, 1877) by Jensen (1994), Yonow et al. (2002), and Yonow (2017) and indeed by Baba in the original description.
