Trinchesia sp. 42 has a translucent whitish body. The annulate rhinophores are translucent whitish, the annulae are whitish. The oral tentacles have a diffuse mid-central golden band. The cerata are translucent whitish with yellow pigment near the apices.
Pretty similar is
Trinchesia sp. 14  Genus: von Ihering, 1879 which differs by smooth rhinophores, by the oral tentacles which have a more vividly coloured band, and by the cerata which have a swelling near the apices.
Trinchesia sp. 42 was posted on 13 September 2016 at these website as Trinchesia sp. 42  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 changed on 23 December 2016 Trinchesia sp. 42  Genus: von Ihering, 1879 into Tenellia sp. 05  Genus: 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 21 October 2017 into Trinchesia sp. 41  Genus: von Ihering, 1879.
