Tenelliasp. 02 is characterized by its brownish colour with lighter club-shaped tips of the cerata. The rhinophores are basally brownish, the outer half has a yellowish tinge. It feeds like all species of this genus on hard corals.
To my knowledge is the above picture the only one of this species, or it is are strange colour form of Phestilla sp. 2 in IPN page 372 and Gosliner et al. (2015) page 357 which has "undulating opaque white patches on the notum and opaque white lines on the relative cylindrical cerata. Ceratal apices club-shaped."
This species was posted on 28 October 2016 at these websites as Phestilla sp. 02  Genus: Bergh, 1874,
Cella et al. (2016) moved it to the Genus Tenellia  A. Costa, 1866 in the Family Fionidae  J.E. Gray, 1857. References:
