摘要：
A new species of dance fly, Alavesia tripudii sp. nov., (Diptera, Empidoidea, Atelestidae), archived in a piece of mid-Cretaceous Burmese amber was described and illustrated based on two individuals of different genders, and a cladistics analysis was also performed to establish its phylogenetic position. Furthermore, our specimen showed a remarkable variation in extremely inflated antennas, which might be used by males for enticing females as nuptial gifts. The new finding not only added additional document to the diversity of dance flies in Burmese amber, but also might be related to possible interactions in dance flies. (C) 2020 Elsevier Ltd.
