Tenellia 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 Flabellina sp. 01, which differs by the papillate rhinophores.
This species was posted on 25 May 2003 at these websites as Cuthona sibogae (Bergh, 1905), I followed Miller (2005) and placed it on 7 December 2010 in the genus Trinchesia von Ihering, 1879.
Cella et al. (2016) moved it to the Genus Tenellia  A. Costa, 1866 in the Family Fionidae  J.E. Gray, 1857.
