( Fig. 2f )

Notomastus (Clistomastus) anoculatus Hartmann-Schröder, 1965: 150 , fig. 78.— Magalhães & Bailey-Brock 2012: 41 –42.

Type material: * Holotype ( ZMH-P15102 ).

Type locality: Eastern Pacific, USA, Hawaii Oahu, Kaneohe Bay , Korallensand , April 17, 1959, on coral sand, littoral .

Records: Only known from the type locality.

Remarks: Magalhães and Bailey-Brock (2012) mentioned that N. (C.) anoculatus presents similarities with N. tenuis Moore, 1909 , particularly on the anterior region and thoracic segments. Based on the examination of type material of N. anoculatus (ZMH-P15102) and N. tenuis (CAS-019718), we realized that there are differences between both species as described below. Notomastus anoculatus has a prostomium with palpode, a tessellated epithelium from the first to the sixth chaetiger, abdominal notopodia very close to each other, and neuropodial lobes expanded to the dorsal part. Notomastus tenuis has a prostomium without palpode, the epithelium is smooth along the body, abdominal notopodia are widely separated and located dorso-laterally, and without neuropodial lobes. Therefore, we consider the validity of N. anoculatus .
