Tenellia sp. 06 is white, mottled with translucent spots. There are thin opaque white lines on the white cerata. It has a small number of cerata. The smooth rhinophores and the oral tentacles are translucent-white mottled, with an orange subapical ring. There is a distinctive orange line between the oral tentacles. It has rounded foot corners. There is a diffuse orange spot at the base of each ceras.
The identification was confirmed by Dr. Richard Willan.
This species was posted on 15 June 2011 at these websites as Trinchesia sp. F  Genus: von Ihering, 1879, and changed on 15 July 2011 into
Trinchesia sp. 06  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 changed on 23 December 2016 Trinchesia sp. 06  Genus: von Ihering, 1879 into Tenellia sp. 06  Genus: A. Costa, 1866.
