It looks somehow similar to Cuthona sp. 29 in IPN at page 368
- by the cerata, which have one single red spot subapically,
- by the rhinophores which are white with an orange-red subapical band,
- by the oral tentacles, which are orange with white tips, and
- by the large opaque white patch on the head
To my knowledge are these the only pictures of this species, it is not in IPN nor at the internet!
The pictures #3 , #4 , and #5 were originally posted on 10 October 2010 at these websites as AEOLIDINA sp. D Suborder: Odhner, 1934, with the comment: "I think it is most probably a Cuthona."
This species was posted on 14 August 2011 at these websites as Trinchesia sp. 19 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. 19 Genus: von Ihering, 1879 into the Genus Tenellia A. Costa, 1866.
Korshunova et al. (2017) restricted the genus Tenellia A. Costa, 1866 to this 3 species:
-Tenellia adspersa (Nordmann, 1845)
-Tenellia chaetopterana Ekimova, Deart & Schepetov, 2017 and
-Tenellia fuscata (Gould, 1870)
and reinstated the family Trinchesiidae F. Nordsieck, 1972 with the genera
-Catriona Winckworth, 1941
-Diaphoreolis Iredale & O'Donoghue, 1923
-Phestilla Bergh, 1874
-Rubramoena Cella, Carmona, Ekimova, Chichvarkhin, Schepetov & Gosliner, 2016
-Tenellia A. Costa, 1866
-Trinchesia von Ihering, 1879 and
-Zelentia Korshunova, Martynov & Picton, 2017
and moved it again into the genus Trinchesia von Ihering, 1879.
I changed it back on 31 October 2017 into Trinchesia sp. 19 Genus: von Ihering, 1879.
