Halgerda cf. wasinensis Eliot, 1904

( Figure 16 J )

Material examined. Nine specimens. MB28-005076, POA, 10 May 2014, 41m, 29mm; MB28-005077, POA, 0 8 May 2014, 41m, 19mm; MB28-005078, POA, 0 8 May 2014, 41m, 29mm. MB28-005079, POA, 0 8 May 2014, 41m, 18mm; MB28-005080, 5 spcs., POA, 10May 2014, 40m, 16–45mm.

Habitats. Subtropical rocky reefs bellow 40m.

Occurrences. Ponta do Ouro.

Geographic distribution. Western Indian Ocean. Mozambique .

Remarks. This morphotype differs from the other H. wasiniensis morphotypes by the presence of a midline on the dorsum rather than the typical network, as well as by large dark spots under the mantle. Moreover, they are found only bellow 38m and on a particular reef in the extreme south of Mozambique. No clear internal differences could be found between this morphotype and the other H. wasinensis and our prelimary molecular analyses do not clearly distinguish these morphotypes. Thus, until additional molecular analyses are completed we cannot know if this morphotype is a variation of H. wasinensis or a recently diverged species.
