Geitodoris sp. #1

Maximum size: about 32 mm.
Identification:
This
is a flat species with low, even papillae. The notum is light to
dusky yellow, variably blotched with cream and brown. The rhinophores
are cream flecked with brown and frosted with white. The branchia are
yellow variably flecked with reddish brown and white. (Note 1)
Natural history:
Geitodoris sp. #1
is known on Maui from only three small animals found in the low
intertidal at a protected rocky site. However, Scott Johnson reports
it as fairly common at 10-15 m (33-49 ft) at a highly exposed rocky
site on
Oahu. It feeds on the black sponge, Tethya
(Bertsch and Johnson, 1981). One of
the Maui animals laid a yellow egg mass with a ribbon that had a
circular cross section.
Distribution:
Maui, Kauai and Oahu.
Taxonomic notes:
This
is the species listed as "yellow dorid" on page 42 in Bertsch and
Johnson,
1981. It was first recorded in Hawaii at Pupukea, Oahu by Scott Johnson
on
July 9,
1979.

Observations and comments:
Note
1: There is some possibility that
lightly blotched, yellow animals might be a second species. However,
the overall form as well as the structure of the branchia, rhinophores
and papillae appear to support lumping. On the other hand, the
difference is probably not related to age since the very small animals
from Maui were heavily blotched. More photos of the yellow form can be
seen at Scott
Johnson's
site.
