Tenellia sp. 32 has a translucent body which is covered with minute orange spots giving an orange appearance, and smooth rhinophores which are basally orange, followed by a translucent whitish patch,then again orange, the outer third is translucent whitish. The oral tentacles are translucent white. The cerata are yellowish-grey, with purple apices, and opaque white cnidosacs.
Pretty similar is Tenellia sp. 27 which has an orange body and white oral tentacles, but differs by the cerata which are red with yellow spots.
There are some pictures of this species from Bali, Indonesia as Tenellia sp. 17 at the Mediterranean Slug Site.
This species was posted on 29 November 2014 at these websites as Trinchesia sp. 32  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 moved on 8 January 2017 Trinchesia sp. 32  Genus: von Ihering, 1879 to the Genus Tenellia  A. Costa, 1866.
