because it was thought to be this species. Gosliner et al. (2015) says this is not the case and calls it Cuthona sp. 13 at page 345, there is a very similar Cuthona sp. 14 at the same page.
I changed it on 18 January 2016 into Trinchesia sp. 41 Genus: von Ihering, 1879.
Cella et al. (2016) moved it to the Genus Tenellia A. Costa, 1866 in the Family Fionidae J.E. Gray, 1857.
let me quote Cella et al. (2016):"Cuthona is polyphyletic although most Cuthona species included in this study clustered together in a large clade.... Within this major clade, two undescribed species, erroneously identified as Cuthona yamasui Hamatani, 1993 appeared here as not one, but two distinct sister species: as Cuthona sp. 13 and Cuthona sp. 14".
This "major clade" is the Genus Tenellia A. Costa. I moved Trinchesia sp. 41 on 19 December 2016 as #04 into the genus Tenellia.
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 18 October 2017 into Trinchesia sp. 41 Genus: von Ihering, 1879.
