摘要
Xenotrichomyia newjerseyiensis a new genus and species belonging to Trichomyiinae within Psychodidae is characterized, described, illustrated and its taxonomic position is discussed. It shares some similarities with Trichomyiinae of group B, but retains some archaic features, such as normal and non-excentric flagellomeres, and possesses an autapomorphy in wing venation that distinguish it from all remaining Trichomyiinae. This discovery represents the first Trichomyiinae (Psychodidae) from the Upper Cretaceous New Jersey amber, and adds more evidence on the very high palaeodiversity of the psychodids since at least the Lower Cretaceous. An updated check list of fossil Trichomyiinae is given.
