Remarks :
 Identification confirmed by Terry Gosliner
According Terry Gosliner : " I am quite certain that the Trapania is not T. euryeia as that species has small spots on the surface of the notum, not on the extrarhinophoral and extrabranchial processes. I am pretty sure you animal represents and undescribed species. "
This species looks like Trapania sp 16 of Rudman Seaslug forum, Trapania sp 5 from Gosliner Indo-Pacific field guide (2008) and some photo of Trapania sp from Nudipixel... but there are some consistent differences...
Bibliographic data :
This species looks like T. brunnea and T. euryeia, but in these two species the
background is white to cream with dark brown patches sparsely scattered with irregular white or
straw coloured small dots.
