Among the scarce Mesozoic fossils, protoischnurid scorpions (Arachnida: Scorpiones: Protoischnuridae) represent a Cretaceous extinct group. In this study, we present the description of a new protoischnurid fossil, assigned to the genus Cretaceoushormiops Loureno, from mid-Cretaceous Burmese amber. Distinguished by a median suture and a comparatively short anterior margin in its carapace, the new specimen differs from all other species within Cretaceoushormiops. Our discovery sheds further light on the high diversity of mid-Cretaceous scorpions.
