Goodheart et al. (2016)[2] list Cadlina burnayi Ortea, 1988 as a synonym of Tyrinna evelinae, but WoRMS (2016) list it as a separate species.[3]
Distribution of Tyrinna evelinae includes Eastern Atlantic, Eastern Pacific, and Western Atlantic: Costa Rica, Venezuela, Jamaica, Puerto Rico, Dominican Republic, Brazil and Panama.[2]
Body is oval to elongate.[2] Background color is usually translucent white with a number of orange spots.[2] Mantle margin is edged by an opaque white line and white mantle glands with orange tips.[2] Rhinophores and branchial leaves are translucent white with opaque white tips.[2] It is up to 30 mm long.[2] Caribbean populations are morphologically indistinguishable from Eastern Pacific and Eastern Atlantic populations.[2]
It is found under rocks and on various sponges.[2] Minimum recorded depth is 0 m.[4] Maximum recorded depth is 5 m.[4]
Tyrinna evelinae in Brazil feeds primarily on dysideid sponges Dysidea etheria, but also upon an unidentified chalinid species (family Chalinidae) of the order Haplosclerida.[5][2] This species has planktotrophic development.[2]
