Abstract:

We describe a new species of Thylacocephala, Ankitokazocaris chaohuensis sp. nov., from the Upper Spathian (Early Triassic) of Chaohu, Anhui Province, China. It is diagnosed by its unique outline of the carapace, small size, and the narrow and asymmetrical anterior notch. Fine preservation reveals at least 14 posterior appendages, traces of gills and raptorial appendages, and remains of trunk segments and muscles in Ankitokazocaris for the first time. This is the first report of Thylacocephala from the Early Triassic of China, confirming the wide distribution of this group in the Tethys. The new species is closer to the type species of Ankitokazocaris, which is stratigraphically somewhat older, than to a recently described almost coeval species from Japan.
