Abstract
A new genus and two new species of extinct paguroid anomurans are described. Capsulapagurus christiaensi n. gen., n. sp. from the middle Albian (Lower Cretaceous) of Pargny-sur-Saulx (Marne, northeast France) is based on a fragmentary, strongly tuberculate right chela with capsulated setae on both external and internal faces of the palm and with the external and internal cutting edges of both fixed finger and dactylus morphologically clearly distinct. The encapsulated setae possibly are indicative of a complex sensory structure which served as an anti-predatory defence mechanism; this is the first mention of such structures from the fossil record. The second species, Dardanus vandeneeckhauti n. sp., from the lower Eocene (Ypresian) at Egem (northwest Belgium), is rare in retaining both coarsely tuberculate chelipeds as well as some pereiopods. This coarse ornament distinguishes the new species from all extinct congeners. Brief comments on other fossil and modern paguroids are added.
