* Favorinus sp. 1 Figure 17K

Material examined.

One specimen 5 mm, CB; one specimen 5 mm, MH.

Ecology.

Documented in habitats ranging from shallow reef rubble and soft sediments to deeper soft sediment habitats. Depth 5-18 m.

Distribution.

Favorinus sp. 8 ( Gosliner et al. 2018) is known from Papua New Guinea and Palau. Here documented as a first record for Thai waters.

Remarks.

Similar to Favorinus sp. 8 in Gosliner et al. (2018) which they record as feeding on the eggs of Stylocheilus striatus under ex-situ conditions. While the prey of the present species has yet to be documented, its range almost directly overlaps with the range of S. striatus from Koh Tao, which grazes on cyanobacteria in shallow and deeper soft sediment habitats at sites CB and SRB.
