Holotype MZS Po0924, geounit Central Kuroshio Current [details]
Type material Tabachnick (2002) stated that the type material was 'unavailable' to him, but mentioned a 'syntype' (2 specimens) from 500 m depth in Sagami Bay. These data were not provided by F.E. Schulze, who described a a single dried specimen collected by L. Döderlein in Sagami Bay without any depth data. The BMNH specimen portal lists no specimen(s) of Rhabdocalyptus mollis, nor of Acanthascus (Rhabdocalyptus) mollis, and the reg.nr. provided by Tabachnick also is not listed in the BMNH portal (and seems to be not in the format of BMNH numbers). The Strassbourg Museum does contain a specimen collected by Döderlein in Sagami Bay with the label Rhabdocalyptus mollis and F.E. Schulze in his Preface of the Challenger Report on the Hexactinellida mentioned Döderlein and the Strassbourg Museum as contributors to his work. We conclude that the MZS material is the holotype and that the 'syntypes' of Tabachnick are not type material. Possibly the mentioned specimens from BMNH and MNHN concern fragments or slides taken from the holotype. [details]
