Abstract
The large Hunsrück Slate arthropodBundenbachiellus giganteus (Broili, 1929) has been interpreted as a myriapod, a possible arthropleurid, and most recently as a distorted specimen of the arachnomorph arthropodCheloniellon. The Single specimen lacks the head region and is characterised by a narrow trunk bearing a series of biramous appendages with a segmented endopod and filamentous exopod. A reinvestigation demonstrates that it is not referable toCheloniellon but represents a distinct taxon of whichEschenbachiellus wuttkensis Briggs &Bartels, 2001, also based on a Single Hunsrück Slate specimen, is a junior synonym. Minor features ofStürmer &Bergström’s (1978) reconstruction ofCheloniellon, which were based on the holotype ofBundenbachiellus giganteus, are revised.
Kurzfassung
Der große ArthropodeBundenbachiellus giganteus (Broili, 1929) aus dem Hunsrückschiefer wurde als Myriapode, als möglicher Arthropleuride und zuletzt als verzerrtes Exemplar des arachnomorphen ArthropodenCheloniellon interpretiert. Dem einzigen bekannten Exemplar fehlt der Kopfbereich, und das Stück wird durch einen schmalen Körper charakterisiert, der eine Reihe von zweiästigen Anhängen mit segmentierten Endopoditen und fadenförmigen Exopoditen trägt. Eine Neuuntersuchung zeigte, dass das Fossil nichtCheloniellon zugeordnet werden kann, sondern eine andere Gattung repräsentiert, für die der NameEschenbachiellus wuttkensis Briggs &Bartels, 2001 — ebenfalls auf nur ein Exemplar aus dem Hunsrückschiefer gegründet — ein jüngeres Synonym bildet. Untergeordnete Elemente der Rekonstruktion vonCheloniellon durchStürmer &BergströM (1978), die auf den Holotypus vonBundenbachiellus giganteus gestützt sind, werden revidiert.
