Trinchesia sp.

Trinchesia cf. caerulea by Enric Madrenas

Data:
This species is very similar to Trinchesia caerulea, quite frequent in the Western Mediterranean. It is probably a different cryptic species. The ceratas have a band of yellow or golden coloured dots below the blue band, and there are bands of iridescent white or yellowish white along the back and sides of the body; the dorsal band usually reaches the front of the head and down to the tip of the tail.

It is present in the Mediterranean from Greece to the Western basin. In the Iberian Peninsula it is found in all its coastal areas, including Portugal. It has also been cited in Balearic islands. In the Catalan coast it has been observed in many localities of the Costa Brava, from the Port de la Selva to Blanes.
