Resumo: Abstract Amblydectes is a problematic genus proposed more than a century ago for several pterosaur specimens from the Cambridge Greensand. Its problematic nature is due to the fragmentary preservation of the referred specimens, limited to several rostral tips. In the present work is reassessed the validity of Amblydectes crassidens based on new anatomical comparisons and phylogenetic analysis, as well as the description of a new specimen. The results of this work confirm the validity of the species as belonging to the clade Tropeognathinae, a recently proposed group of robust anhanguerids which have only been known so far from Gondwanan landmasses. Amblydectes is proposed as a monospecific genus, whilst one the former attributed species is assigned to a new genus, Draigwenia, which is proposed as a non-anhanguerian lanceodontian taxon of uncertain placement. The presence of a tropeognathine anhanguerid in the Cambridge Greensand suggests that anhanguerid diversity was really complex both locally and globally.
