Taxonomic history

This species was synonymised with Pleurolidia juliae by Rudman.[3] A careful study by Carmona et al. using DNA sequencing showed that these were really two sister species and that they were not members of the family Aeolidiidae.[4]

Distribution

This species was described from Kasajima, Sagami Bay, Japan. It is also known from Korea.[4]

Description

Protaeolidiella atra is an aeolid nudibranch with a burgundy to black coloured body and numerous cerata with white tips.[4] It is confused with Pleurolidia juliae in many works but can be distinguished by the lack of a dorsal white line on the body and more numerous, ungrouped cerata.[5]

gollark: Peer pressure!
gollark: _is incredibly indecisive, as usual_
gollark: Getting four reds as hatchlings is much more convenient then messing around with growing them for ages.
gollark: 2G prizekin.
