A new species of Trigonidiidae, †Qiongqi multispurous sp. nov., is described from mid-Cretaceous Kachinamber. It can be definitely attributed to the family Trigonidiidae, but excluded from the two extant subfamilies. It also exhibitsa different morphology from all reported trigonidiids genera and species from the Mesozoic, including subapical/apicalspurs on the hind tibia and setae-like processes on the hind basitarsomere. This new discovery provides novel morphologicalinformation of Cretaceous Trigonidiidae, and highlights the potential of biodiversity of Cretaceous crickets.
