Thuridilla cf gracilis (Risbec, 1928)
20mm

We cannot make up our minds on whether these more closely match Thuridilla gracilis or T. ratna as redescribed in Martín-Hervás, et al (2021). Our specimens differ from both in the presence of a central white band on the rhinophores. Some of our photos show red tips to the rhinophores while others do not. Where the anterior pedal edges can be seen, they appear to be tinted with orange. We are going to call them T. cf gracilis, but it will probably take DNA analysis to properly identify them. We saw at least four of these in shallow water at Tulamben and another at Bayu.
