Millipedes from the Gres a Voltzia, Triassic of France, with comments on Mesozoic millipedes (Diplopoda: Helminthomorpha: Eugnatha)

摘要

Hannibaliulus wilsonae, n. gen., n. sp. is described from a series of ten specimens from the early Triassic Gres a Voltzia Lagerstatte of north-east France. The best specimens (holotype and paratype) show a probably equal number of around 44 diplosegments. The affinities of the new species appear to be with the Order Callipodida, but clear apomorphies of that order are not observable on the specimens, both of which appear to be female. Other records of Mesozoic diplopods are briefly discussed and evaluated.
