Trinchesia sp. 03 has a whitish body with a bluish-pink tinge. The smooth rhinophores are translucent orange, with a broad white median band. There is a distinctive white patch on the head between the rhinophores and the oral tentacles. the "tail" and the edge of the foot are pale violet. The oral tentacles are translucent orange. The cerata are white with diffuse pale bluish apices.
This shot shows a specimen feeding on a hydrozoan, probably genus Corymorpha, this shot shows its egg-mass. It is very common at Dauin, Negros Oriental.
This species is most likely as Cuthona sp. 14 in IPN at page 364.
It was posted on 27 September 2003 at these websites as AEOLIDINA sp. A Suborder: Odhner, 1934, I was pretty sure that it is Cuthona sp. 14 in IPN and
changed it into Cuthona sp. C  Genus: Alder & Hancock, 1855, I followed Miller (2004) and moved it on 14 June 2011 into the genus Trinchesia von Ihering, 1879,
and changed it on 15 July 2011 into Trinchesia sp. 03  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 11 January 2017 Trinchesia sp. 03  Genus: von Ihering, 1879 as #40 into the genus Tenellia  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 22 October 2017 into Trinchesia sp. 03  Genus: von Ihering, 1879.
