New barklice (Psocodea, Trogiomorpha) from Lower Cretaceous Spanish amber

Barklice are insects belonging to the order Psocodea. They are herbivorous or detritivorous, and inhabit a wide range of environments. Their oldest fossil record dates back to the late Carboniferous, but it was not until the Cretaceous that they became much more diverse. However, their fossil record...

description Barklice are insects belonging to the order Psocodea. They are herbivorous or detritivorous, and inhabit a wide range of environments. Their oldest fossil record dates back to the late Carboniferous, but it was not until the Cretaceous that they became much more diverse. However, their fossil record could be affected by taphonomic processes due to their tiny size and soft bodies. Here, we present new psocid specimens from five amber-bearing outcrops in Spain that are Albian in age. One of the specimens, a well-preserved psocid nymph assigned to ¿Archaeatropidae, lacks evidence of debris-carrying behaviour. Some of the specimens belong to the previously known species Archaeatropos alavensis Baz & Ortuño and Preempheria antiqua Baz & Ortuño (Trogiomorpha: Atropetae), providing new anatomical and biogeographical information.
