Euplastius
A genus of click beetles (Elateridae) described by Schwarz in 1903. The taxonomic status is currently marked as doubtful, indicating uncertainty about its validity as a distinct genus. Limited information is available about its constituent species and biology.
Pinaxister decipiens
clown beetle
Pinaxister decipiens is a species of clown beetle in the family Histeridae. It occurs in North America, with records from Arizona and Texas. As a member of the subfamily Haeteriinae, it belongs to a group of histerid beetles often associated with social insects, though specific ecological relationships for this species remain poorly documented.
Scarabaeoidea
Scarabs, Stag Beetles, Dung Beetles, Fruit and Flower Chafers
Scarabaeoidea is a superfamily of beetles comprising approximately 35,000 described species, with around 200 new species described annually. It is the sole superfamily within the infraorder Scarabaeiformia. The group includes diverse families such as Scarabaeidae (scarabs, dung beetles, chafers), Lucanidae (stag beetles), Geotrupidae (earth-boring scarabs), and Bolboceratidae. Many species exhibit distinctive circularly polarized light reflection from their cuticles, produced by helicoidal stacks of chitin microfibrils. The superfamily is currently undergoing taxonomic revision at the family level.
