Trinchesia sp. 41 was misidentified and posted on 25 May 2003 at these website as Cuthona yamasui (Hamatani, 1993) (which was moved by Cella et al. (2016) into the genus Tenellia  A. Costa, 1866, and by Korshunova et al. (2017) into the genus Trinchesia  von Ihering, 1879),
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.
