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 to the Genus Tenellia.
