Armina sp. 06 can be distinguished from other arminaceans by the black foot with an pale yellow margin followed by pale blue, and the transverse black patches on the mantle. The mantle has an orange-red margin. The oral veil is black with an orange margin and a diffuse blue patch on the anterior portion. The rhinophores are black with an orange-red apex, between the rhinophores is a small diffuse blue patch.
Pretty similar are:
Armina sp. 02 which lacks the diffuse blue patch on the anterior portion of the oral veil and has a black foot with an orange-red margin followed by an interior diffuse blue band,
Armina magna which has an orange margin of the black foot, and has black rhinophores with a yellow apex, and
Armina sp. 08 which differs by its greyish foot with a diffuse whitish margin, by the greyish oral veil with a pale orange margin, and by the orange rhinophores.
It was posted at these websites before as Armina sp. F Genus: Rafinesque, 1814.
For some genera, such as Trinchesia was the alphabet almost through. I had to change the distinguishing alphabetic character into a number. I had chosen 2-digit numbers, even though '01' looks a little bit stupid, and now is only the genus italic written.
