Ipelates
Ipelates is a genus of primitive carrion beetles in the family Agyrtidae. The genus contains at least four described species. These beetles are classified within the superfamily Staphylinoidea and are considered among the more basal lineages of carrion-associated beetles. Species in this genus have been documented from fossil and extant contexts.
Malthodes
soldier beetles
Malthodes is a genus of soldier beetles in the family Cantharidae, containing at least 120 described species. The genus has a long evolutionary history, with fossil relatives dating back to the Late Cretaceous (~99 million years ago). Extant species are distributed across the Palaearctic region, including Europe, the Caucasus, and East Asia. The genus is taxonomically active, with new species described recently from Japan and the Greater Caucasus.
Pseudopsinae
Pseudopsinae is a small subfamily of rove beetles (Staphylinidae) containing four extant genera—Pseudopsis, Nanobius, Asemobius, and Zalobius—with approximately 55 species. The subfamily is distinguished by longitudinal carinae on the head, pronotum, and elytra, and a fine stridulatory file on the genital segment. Fossil records extend to the Lower Cretaceous (~125 Ma), indicating an ancient origin. Members inhabit moist microhabitats including forest leaf litter, fungi, and riparian moss.
Zopheridae
Ironclad beetles
Zopheridae is a family of beetles in the superfamily Tenebrionoidea, commonly known as ironclad beetles. The family has expanded considerably in recent years to include the former families Monommatidae and Colydiidae as subfamilies or tribes. It comprises approximately 190 genera and 1700 species distributed worldwide. Members are characterized by exceptionally hardened exoskeletons that make specimens difficult to pin for collection. The family includes diverse feeding habits, with many species associated with rotting wood or fungus, while some Colydiinae are predatory or feed on living plant tissue.
