Atagema scabriuscula (Pease, 1860)
Maximum size: 25 mm.
Identification:
This
is
a firm, dingy-gray species. The notum is covered by a network
of papillate ridges that vary in height creating a series of
broad depressions. The papillae may be tipped in white and the spaces
between
the ridges in the depressions are filled with brown pigment. The
rhinophores are blotched with brown.
Natural history:
Atagema scabriuscula
is a moderately common nocturnal species found in tide pools and the
low intertidal at protected to moderately exposed rocky sites. Rarely,
it can be found subtidally to 10 m (33 ft) at highly exposed sites. It
lays
a cream egg mass that hatches in about six days in the laboratory.
Distribution:
Big Island, Maui, Oahu and Kauai: probably
widely distributed in the Indo-Pacific.
Taxonomic notes:
This
is
the species that Kay, 1979 as well as Kay & Young, 1969 list as Trippa
scabriuscula. It was first
reported from
Hawaii in Pease, 1860 (as Doris scabriuscula).
