Halgerda sp. 1

( Figure 16 K )

Material examined. Two specimens. MB28-004661, ZD, 26 Mar. 2013, 32m, 16mm. MB28-004721, ZT, 11 Aug. 2013, 42m, 42mm.

Habitats. Subtropical rocky reefs.

Occurrences. Zavora.

Geographic distribution. Western Indian Ocean. South Africa ( Coleman 2008) and Mozambique.

Remarks. This species is similar to H. maricola ( Fahey & Gosliner 2001) from Western Australia; it differs externally by the presence of much larger spots between the ridges and linned as opposed to spotted gills. Debelius and Kuiter (2007, pg. 235) illustrate a photograph of a Halgerda from western Australia which is externally more similar to this species than to the description of H. maricola , nevertheless without further examination of such a specimen is not possible to confirm its identity.
