Part and counterpart of a well-preserved specimen of Gondekia lancifer (Reimann, 1945a), and a well-preserved specimen of Pseudohydnoceras erraticum Reimann, 1935, are described from the Wanakah Member of the Middle Devonian, Givetian, Ludlowville Formation, of western New York State. The specimen of Gondekia is only the second articulated specimen known and is more complete than the holotype. It has an intact skeleton of felted sexiradiates of three orders of spicules; the largest has rays approximately 2 mm long. The specimen of Pseudohydnoceras has preserved hexactine-based spicules in a dictyid skeleton, described for the species for the first time.

AbstractMicrodecemplex rolfei, gen. and sp. nov., a new microarthropleuridean less than 5 mm long, is described from the Middle Devonian Panther Mountain Formation of New York State, U.S.A. The specimens consist of organically preserved cuticle, with some preserving the only cephalic structures known for arthropleurideans. A new order, Microdecemplicida, and a new family, Microdecemplicidae, are established. The probable phylogenetic position of the Microdecemplicida as one of the basal clades of Diplopoda is proposed.
