Tenellia sp. 07 is translucent red, between the cerata opaque white. The cerata are wine-red with diffuse whitish apices and diffuse dark red subapical rings. Some of the cerata have a few minute white spots. The smooth rhinophores and the oral tentacles are purple.
This specimen lacks the minute white spots on the cerata.
This species is as Cuthona sp. 34 in IPN at page 369, it was posted on 20 June 2011 at these websites as Trinchesia sp. G  Genus: von Ihering, 1879,
and changed on 15 July 2011 into Trinchesia sp. 07  Genus: von Ihering, 1879.
For some genera, such as Trinchesia was the alphabet almost through. I had to change the distinguishing alphabetic character into a number. I had chosen 2-digit numbers, even though '01' looks a little bit stupid, and now is only the genus italic written.
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 24 December 2016 Trinchesia sp. 07  Genus: von Ihering, 1879 to the Genus Tenellia  A. Costa, 1866.
