First representatives of the extinct family Eoptychopteridae (all males), belonging to Leptychoptera dimkina and L. vovkina gen. et spp. nov. (subfamily Eoptychopterinae), from the Early Cretaceous Lebanese amber are described. Many of their characters are similar to extant Ptychopteridae, among them the presence of prehalter is the most interesting. The larval mite in the feeding position is found on the abdomen of the L. dimkina sp. nov. holotype.
