Abstract

Two new species of Hybristodryinus Engel, 2005, are described from mid-Cretaceous amber of northern Myanmar: H. castaneussp. nov. (based on one male) and H. zaifuisp. nov. (based on one female). Keys to the females and males of Hybristodryinus species are modified to include the two new taxa. A syninclusion, a nymph of Cixitettiginae (Perforissidae), present in the same amber piece containing H. zaifui, is studied. This syninclusion, together with the presence of Antennal Dorsal Organs (ADOs) in Hybristodryinus, suggests that Perforissidae are possible hosts of Hybristodryinus.
