Abstract
A remarkable new genus and species, Mecocollaris simplipodus gen. et sp. nov. is described from mid-Cretaceous amber. It is the second fossil record of Nabinae from Myanmar amber. The new species is distinguished from other nabids based on labial segment Ⅲ longer than the combination of segments I, Ⅱ and Ⅳ, hind tibia without clear row of setae corresponding to stiff setae associated with the Ekblom’s organ. By comparing extant species and fossil records of Nabidae, the evolution of the Ekblom’s organ of nabids is discussed.
