Abstract

ABSTRACT A new genus and species of Empididae (Diptera) in mid-Cretaceous Burmese amber is described as Neoalavesia hadroceria gen. et sp. nov. in the subfamily Atelestinae. The male is characterised by its small size, unique wing venation with reduced cell dm and the greatly expanded postpedicels that may have been used as sexual attractants. A novel feature of the fossil is a small, elongate, glutinous structure containing numerous filiform, sperm-like bodies adjacent to the abdominal terminus.
