Tenellia sp. 33 has a translucent whitish body with a bluish tinge. The smooth rhinophores are basally translucent, the outer half is yellowish/orange. The oral tentacles are frosted white. The cerata are basally translucent merging in the outer half to yellowish/orange, and are in the whole length covered with minute white spots giving a frosted appearance.This 3 mm specimen is most probably a juvenile.
This species was posted on 29 January 2015 at these websites as Trinchesia sp. 33  Genus: von Ihering, 1879.
Cella et al. (2016) restricted the genus Cuthona  Alder & Hancock, 1855 to the type species, C. nana (Alder & Hancock, 1842) just like Miller (2004) did, and synonymised the genera
- Catriona  Winckworth, 1941,
- Phestilla  Bergh, 1874,
- Cuthona  Alder & Hancock, 1855 (partim), and
- Trinchesia  Ihering, 1879
with Tenellia  A. Costa, 1866 in the Family Fionidae  J.E. Gray, 1857.
I moved on 9 January 2017 Trinchesia sp. 33  Genus: von Ihering, 1879 to the Genus Tenellia  A. Costa, 1866.
