Chromodoris petechialis Gould,
1852

Maximum size: 70
mm (Gosliner, et. al., 2008).
Identification:
This
species
has
a
pale-salmon
notum
spotted
with
red
and
margined
with
yellow.
The rhinophores are yellow and the gills are white
with red lines on their inner and outer surfaces.
The notum is decorated with low, conical pustules
that distinguish it from the similar appearing Chromodoris
sp. #1. It differs from Chromodoris
sp. #5 in its darker background color and
spotted (as opposed to reticulate) notum.
Natural history:
Chromodoris
petechialis is known from one animal found
at Honolulu in the 1800s (the basis of the 1852
description) and two animals photographed on Oahu in
1959. The 1959 animals may have come from Kaneohe
Bay, a shallow highly protected site.
Distribution:
Oahu.
Taxonomic notes:
This
species
was
first
reported
from Hawaii in Gould, 1852 and appears to be closely
related to Chromodoris
sp. #5 with both species being part of the
Indo-Pacific Chromodoris
tinctoria complex. For further discussion
see The
Sea Slug Forum. There is some possibility Chromodoris sp.
#5 might ultimately prove to be a color form of C. petechialis.
The name means “blood vessel hemorrhages” referring
to the pattern on the notum.
