Richard Willan writes on this species: "Evidently from your photos it has large simple rhinophores, relatively small oral tentacles, a rounded foot border, and cerata in transverse rows. All these features point to it being one of the large Trinchesia (formerly called Cuthona) species in the family Tergipedidae."
This species was posted on 31 May 2011 at these websites as Cuthona sp. D Genus: Alder & Hancock, 1842, on 14 June 2011 changed into
Trinchesia sp. D Genus: von Ihering, 1879, and on 15 July 2011 changed into Trinchesia sp. 04 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 11 January 2017 Trinchesia sp. 04 Genus: von Ihering, 1879 as #41 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 23 October 2017 into Trinchesia sp. 04 Genus: von Ihering, 1879.
