Havelockia ferali ferali Cherbonnier, 1988

Havelockia ferali Cherbonnier, 1988: 183 , text-fig. 78 A–M.

Diagnosis (after Cherbonnier 1988). A small, sclerodactylid holothuroid, yellowish in colour, sometimes with some brownish spots. Body in-curved, length 13–17 mm. Tube feet long, scattered, with some apparent serial arrangement. Tentacles 10, mid-ventral two greatly reduced. Calcareous ring unfragmented but processes clearly subdivided. Polian vesicle and stone canal single, madreporite not calcified. Body wall ossicles as tables with fusiform or triangular disc pierced by four central holes accompanied by two or more supplementary holes; spire of two arched-pillars terminating in a non-perforate, spinous crown; smooth multilocular plates also present. Anal tables with smaller disc but usually with perforated crown to spire. Tube feet ossicles as tables with a curved disc and a toothed, terminally pierced spire. Introvert supported by tables with large multilocular disc. Tentacles with rosettes or rosette-like plates.

Holotype. MNHN EcHh 3544, Tuléar, Madagascar.

Paratypes. MNHN EcHh 7077, 7076, 7077 and 3591 (all from Nosy Bay, Madagascar).

Remarks. This is the nominal subspecies of Thyone ferali and is not represented in the material at hand. It was described from the holotype and several paratypes but Cherbonnier (1988) mentioned that his description related only to the holotype. The author has had the opportunity to study all the type material at the MNHN and his observations are here contained in the remarks section under the new subspecies described below.
