154 those parts of the material (the serial sections), on which the original description was based, with most other undissected material being para(lecto)types. This turned out to be essentially crucial in case of Dorymenia/Proneomenia antarctica Thiele and Labidoherpia/Pruvotina spinosa Thiele (for details see under the species). Lectotype designation are here done in accordance with the purpose of Article 74.7.3. of the current issue of the ICZN in order to ensure the name’s proper and consistent application.

Section A – Alphabetic list of Solenogastres type material in the Malacozoological Collection of the Berlin Museum of Natural History No type material of the second major aplacophoran group, the Caudofoveata, is held in the ZMB (but see remark under Chaetoderma productum). However, some non-type material of Chaetodermomorpha is present which is listed together with non-type material of the Solenogastres in section B.

C o m m e n t s : Re-examination and determination as Dorymenia antarctica (Thiele, 1913a) by Salvini-Plawen (1978), who was then provided, unfortunately, with only part of the holotype serial sections by R. Kilias (n ¼ 3 slides, with label “Q1925 g–i), thus his statement “von der Original-Schnittserie liegen drei Objektträger vor (Hinterende part.)” (Salvini-Plawen 1978: 247). We verify herewith that the holotype is completely extant, mentioned by Thiele originally as “untersuchtes Tier” in his publication, with serial sections of the animal’s anterior and posterior part. Re-examination by LvS-P of the postradular sections reveals that Thiele’s description is brief but correct.

Mitt. Mus. Nat.kd. Berl., Zool. Reihe 81 (2005) 2 / http://museum-zool.wiley-vch.de 155 Fig. 1. Johannes Thiele (1860–1935) made numerous histological serial sections of aplacophoran molluscs, deposited in the Malacozoological Collection of the Berlin Natural History Museum today. Illustrated here are two examples of his original serial sections: – A –“Proneomenia” (¼ Dorymenia) hoffmani (Salvini-Plawen, 1978), two microscopic slides with cross-sections of Thiele’s series Q 1926 a–k (ZMB Moll. 105.420); Thiele originally assigned this material to “Proneomenia” antarctica (Thiele, 1913a), but later separated it from this species (see Salvini-Plawen 1978). – B –“Proneomenia” (¼ Epimenia) australis (Thiele, 1897), two slides with cross-sections of series 3070 (ZMB Moll. 105.407). Note Thiele’s handwriting on the original labels glued onto the slides.

Ty p e m a t e r i a l : ZMB Moll. 105.407a, parts of holotype, serial sections on 48 slides, Thiele fec. (labelled 1–36, anterior part, “Q 3070a–LL; and 1–12 posterior part, “Q 3070 mm–xx); ZMB Moll. 105.407b, 2 parts of holotype. C o m m e n t s : Transferred by Nierstrasz (1908) as type species, by monotypy, to his new genus Epimenia, which is characterized by unusually large (up to 300 mm) and bright coloured species that occur on the continental shelf and are found even close to shore at diving depths. Six named congeneric species are known today, with more taxa to be described within the family Epimeniidae (see Scheltema 2001: 10).
