Unidentified
Discodorid #20

Maximum size: about 8-9 mm.
Identification:
This
is
a cream dorid with very small,
rounded tubercles that are slightly darker than the background. The
tubercles are surrounded be rings of minute white flecks and dark brown
flecks are present both between and on them. The rhinophores have white
tips
and subapical brown pigment. The branchia are bi-colored with cream
pigment on the anterior plumes. There's a low, mid-dorsal crest and the
margin is slightly frilly.
Natural history:
Unidentified
discodorid
#20 is known from one animal found in a tide pool at an exposed, rocky site.
Distribution: Maui.
Taxonomic notes:
It may be a Carminodoris sp. based on the rounded tubercles and
bi-colored branchia. However, a mid-dorsal crest and frilly margin would
be atypical for the genus. The tubercles are proportionately smaller than in Carminodoris sp. #2 and the color is different on several points. The branchia differ from Unidentified Discodorid #19. It was first recorded
in Hawaii from the north shore of Maui by Britt Daniels on Aug. 9,
2021. (Note 1)

Observations and comments:
Note
1: It's possible that this animal is a
juvenile of one of the other listed species. But, there doesn't seem to
be an obvious match.
