Tenellia sp. 22 is characterized by its transparent foot which has brownish-orange pigment at the posterior end, and by the opaque white body. The slightly annulate rhinophores are brown with a diffuse whitish medial band. The oral tentacles are orange with white spots, and white apices. The ceratal wall is transparent covered with minute opaque white spots merging into an opage white subapical region, the apices are translucent, distinctive is the brown highly branched ceratal core.
This specimen was identified by David W. Behrens, he wrote: "Cuthona sp. new", thanks!
To my knowledge are these the only pictures of this species, it is not in IPN nor at the internet!
This species was posted on 13 September 2011 at these websites as Trinchesia sp. 22  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 2 January 2017 Trinchesia sp. 22  Genus: von Ihering, 1879 to the Genus Tenellia  A. Costa, 1866.
