Sclerodoris sp. #2
Maximum size: 70 mm (Kay,
1979).
Identification:
This
is a dusky yellow dorid with broad depressions on its notum
containing variable amounts of dark pigment. The ridges between the
depressions are flattened and decorated with small tubercles, contractile papillae and
secondary depressions. With growth, the ridges become more prominent and more dark pigment develops in the depressions.
Natural history:
Sclerodoris sp. #2
is a rare nocturnal species known from only a few animals. It shelters
under rocks or in crevices
during the day. It has been found in moderately exposed to exposed
locations from 1.5-19 m (5-63 ft).
Distribution:
Big Island, Maui and Oahu: also known from Vanuatu and Papua New Guinea.
Taxonomic notes:
The
first Sclerodoris sp. in
Kay, 1979 appears to be this species. It was first reported in Hawaii
from Ala Moana, Oahu in April
1962 (Kay & Young, 1969--as Halgerda apiculata). Some of the animals illustrated as Sclerodoris apiculata (Alder &
Hancock, 1864) on the Sea Slug
Forum are also probably this species (the two are treated as
distinct in Gosliner, et. al. 2018 with "Sclerodoris sp. 2" being this one).
