Click the thumbnail photos to enhance!

Trinchesia sibogae has a pale lilac purple body, the oral tentacles and the slender smooth rhinophores are pale lilac purple at the base, the upper half reddish purple. The cerata are pale lilac purple with a deep reddish purple to deep purple subapical band and a bright golden yellow tip. It feeds on an orange-yellow hydroid of the genus Sertularella.
Pretty similar is Coryphellina sp. 01, which differs by the orange papillate rhinophores.
This species was posted on 25 May 2003 at these websites as Cuthona sibogae (Bergh, 1905), I followed Miller (2004) and placed it on 7 December 2010 in the genus Trinchesia  von Ihering, 1879.
Cella et al. (2016) moved it into the genus Tenellia  A. Costa, 1866 in the family Fionidae  J.E. Gray, 1857.
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 T. sibogae (Bergh, 1905) again into the genus Trinchesia  von Ihering, 1879.
I changed it again on 16 October 2017 into Trinchesia sibogae (Bergh, 1905) [Hervia].
