Cryptorhopalum
Cryptorhopalum is a genus of skin beetles (family Dermestidae) known only from the Americas, ranging from North to South America. The genus includes both extant and fossil species, with several species preserved in amber. The immature stages of at least one species, C. triste, have been described in detail.
Dermestidae
skin beetles, carpet beetles, larder beetles, hide beetles, leather beetles, khapra beetles
Dermestidae is a family of beetles comprising approximately 1,700 to 1,800 described species worldwide. Adults are small (1–12 mm), typically oval to rounded, with antennae that are clubbed and usually concealed in thoracic grooves. The family exhibits exceptional diversity in feeding ecology: larvae of most species are scavengers specialized on dry organic matter, particularly keratin-rich materials including animal hair, feathers, hides, wool, and silk. Certain genera have evolved highly specific associations, such as Thaumaglossa in mantid egg cases. The family includes significant economic pests (carpet beetles, khapra beetle), forensic indicators (hide beetles), and beneficial species used in taxidermy and museum specimen preparation. Larvae of subfamily Megatominae possess distinctive defensive hastisetae—barbed, spear-tipped setae that detach to entangle predators.
Omorgus tytus
Omorgus tytus is a skin beetle in the family Trogidae, a group of beetles commonly associated with decomposing organic matter. The species has been documented across multiple U.S. states in the Nearctic region. Like other members of the genus, it is presumed to be a detritivore or scavenger, though specific ecological details remain poorly documented in the literature.
