	Classification according to Bouchet et al. (2017) Taxonomic source: World Register of Marine Species (AphiaID: 1473661).

Taxonomic note: Initially classified within the genus Tritonia, Korshunova & Martynov (2020) suggest the possibility of transferring this species to the genus Duvaucelia, but given that the description of this species indicates that it has a bilobed frontal veil, and in the absence of genetic analysis, it is most likely to belong to the genus Tritonia, following the criteria established by these authors.

Description
Small body (holotype size is 7.5 mm long), with a square section and yellow in color, with the edge of the mantle and the space between the rhinophores of a more intense yellow, with an orange hue. Towards the middle of the back there are two centered, oval and bulging white spots. The body has a uniform width from the head to the middle, then tapering to the tail. The head has a bilobed anterior veil, with five small bifurcated branches on each of the lobes, regularly spaced along the edge. On the margins of the notum there are ten pairs of branchial arborizations, the first two pairs poorly developed and then those located in odd positions (3, 5, 7 and 9) more developed and bifurcated than those located in even positions (4, 6, 8 and 10). The rhinophores are protected by a very tall, yellow rhinophoric sheath, with a rounded edge and somewhat opened to the outside; rhinophores with a well-developed yellow mucron that contrasts with the ring of surrounding papillae, which are hyaline and with a white apex. When the rhinophores are extended, the papillae can be longer than the mucron itself. Eyes located at the posterior base of the rhinophores, where they can be seen by transparency. The foot has a rounded anterior edge and otherwise it has the same shape as the body.

Biology
The only captured specimen was found among coral and hydrozoan fragments trapped in a net set at 200 meters deep. Nothing else is known of its biology.

Etymology

Taliartensis, related to Taliarte, a town located on the island of Gran Canaria, close to the point where the holotype was collected.

Distribution
It is only known based on a single specimen captured in February 1983 in Taliarte, Telde, Gran Canaria.
