158 Fig. 2. Habitus of one juvenile of Ocheyoherpia kerguelensis Salvini-Plawen, 2005 (ZMB 105.395b; paratype); the complete material of this new taxon, including three juvenile animals, was originally labelled “Pruvotina kerguelensis“ by Thiele, but only recently validly named and described by Salvini-Plawen (2005); see text for more details. Scale ¼ 0.5 mm. Ty p e l o c a l i t y : “Neapel”; Mediterranean Sea: Gulf of Naples. Ty p e m a t e r i a l : ZMB Moll. 105.429, holotype, serial sections on 14 slides, from animal (c. 3 cm in length and 1.5 mm thick according to Thiele (1894: 244)); Thiele fec. (labelled “CCII a–o”). C o m m e n t s : Type-species, by monotypy, of Amphimenia Thiele, 1894; as new subgenus of Proneomenia Hubrecht, 1880. Currently transferred to the Amphimeniidae. This taxon, described together with Neomenia grandis and Rhopalomenia eisigi by Thiele (1894), was long missing from the ZMB collection as was also Proneomenia vagans. Uncovering the odyssee of all this material from the available evidence, we reconstruct that it was given by Thiele in the late 1920th/early 1930th on loan for the preparation of the Naples monograph to H. F. Nierstrasz at the University Museum in Utrecht (Nierstrasz in Nierstrasz & Stork 1940: 1). After Nierstrasz’ death (Sept. 1937) the material remained in Utrecht until the university stopped its systematic research. Thiele’s material was sent in 1956 to the then curator at the Zoological Museum in Amsterdam, T. Van Bentem-Jutting (while other material from Utrecht was transferred at the same time to the Natural History Museum in Leiden). In search of the type-material, it was traced out in May 1977 by LvS-P together with S. Van der Spoel, the then curator at the ZMA, on the occassion of a visit to the collection of the ZMA. LvS-P made exact notes about the boxes in which Thiele’s original material in the ZMA were deposited. Triggered by this forwarded information, the material was finally rediscovered in the ZMA and thankfully sent back # 2005 WILEY-VCH Verlag GmbH & Co.
