 Atagema scabriuscula
(Pease, 1860)
 
Atagema scabriuscula
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).
