Description
Diaulula hispida (d'Orbigny, 1834)
Material examined. Argentina, San Matías gulf, Caleta Los Hornitos, BENTOS 2008, two specimens, 65 m (ESCM-Ma-22).
Description. Length up to 80 mm, body whitish with brown dots, or body completely brown to dark brown. Undulating dorsal ridge. Mantle covered by very thin caryophyllidia, forming a collar at the base of the rhinophores. 6-7 tripinnate gill leaves surround the anal papilla. Oral tentacles digitiform. Foot bilabiate, with upper lip notched. The radular formula is 24 x 32.0.32. The lateral teeth are simple and smooth.
Geographic distribution and depth range. Argentina, from Comodoro Rivadavia, Chubut to central Chile in Valparaiso, Chile (Schrödl 1996, 1997a, 2000, 2003). Found at 65 m depth.
Remarks. According to Valdés & Gosliner (2001) D. hispida is characterized by a notum ridge, common to the members of the genus Atagema Gray, J.E. 1850 (= Trippa see Marcus 1959). On the contrary, Marcus (1959) considered that this species fits better within the genus Diaulula, due to morphological differences in the mouth of Trippa species. Until more information is available, D. hispida should be maintained in Diaulula (Schrödl 2003).
