Sclerodoris
sp. #2

 
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 and secondary 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. 2008).
