From Peng et al. 2015, p. 2: "The systematics of Mesozoic psychopsoids is very complicated and confused. This group of Neuroptera includes taxa with broad and multi-veined wings that are currently classified in five families, i.e. Osmylopsychopidae, Brongniartiellidae, Psychopsidae, Kalligrammatidae and Aetheogrammatidae (Makarkin et al. 2013). Kalligrammatidae and Aetheogrammatidae are easily distinguished from other psychopsoids, whereas the Mesozoic members of the three other families (i.e. Osmylopsychopidae, Brongniartiellidae and Psychopsidae) hardly differ from each other.". Determined in Mai 2023 by Dr. Vladimir N. Makarkin, Institute of Biology and Soil Sciences, Far Eastern Branch of the Russian Academy of Sciences, Vladivostok, Russia: "This is a species of Osmylopsychopidae, possibly new."

Extinct Big Water Predator Insect, Chresmodid, in Burmite?
Biotalker posted a topic in General Fossil Discussion
Chresmodidae are a family of insects that reigned from Middle Jurassic to Late Cretaceous. They are medium to large insects with very long legs and superficially resemble extant water striders. While they were common in water environments, like Daohugou, they are exceedingly rare in land environments like burmite. They are puzzling critters, since scientists suggest it is unlikely these weighty insects had the buoyancy necessary to be water surface predators like water striders (Gerridae, Hemiptera). These are samples of Daohugou Chresmodid fossils.

Insect non det. (Mecoptera or Scorpionfly?) Middle Jurassic Daohugou Nei Mongol China -
Hi everyone, My friend bough some of Daohugou fossils for his museum and he asking to help for the ID. The only information that we got these fossils came from Nei Mongols, China. So do you have any idea about these fossil pls help us. Thanks for reading 1.
