However, a newly described technique for extracting DNA from formalin-fixed material offers new opportunities for molecular phylogenies of Aplacophora (Schander and Halanych, 2003; Skage and Schander, 2007).
An annotated catalogue of Thiele's type specimens, with a brief review of "Aplacophora" classification.
Aplacophora as progenetic aculiferans and the coelomate origin of mollusks as the sister taxon of Sipuncula.
Of the two Aplacophora taxa, we believe the neomeniolds are the less derived (Scheltema, 1993, 1996; Scheltema et al., 1994; Ivanov, 1996), and are thus particularly important in considerations of the phylogeny of molluscs.
Species were selected from the following collections of Aplacophora: West European Basin (INCAL, 15 July to 11 August, 1976, Centre National de Tri d'Oc6anographie Biologique [CENTOB]; and RV Chain Cruise 106, 15 August to 6 September, 1972, Woods Hole Oceanographic Institution); off Gibraltar (BALGIM, 25 May to 22 June, 1984, CENTOB); Bass Strait (Bass Strait Survey 1979-1984, Museum of Victoria, Australia); and Argentine Basin (RV Atlantis II Cruise 60, 10.iii-30.iii.1971).
