This picture shows also a specimen of Facelinidae sp. 04.
It looks somehow similar to Catriona sp. in IPN at page 371,
which differs by the cerata, which are swollen subapically, with a narrow tip, and by the thin subapical orange band, broad in Tenellia sp. 18.
The size of the above specimen was not recorded.
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 30 July 2011 at these websites as Trinchesia sp. 18 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 31 December 2016 Trinchesia sp. 18 Genus: von Ihering, 1879 to the Genus Tenellia A. Costa, 1866.
