Vitellius
Vitellius is a genus of click beetles in the family Eucnemidae, established by Bonvouloir in 1871. The genus belongs to the order Coleoptera and is part of the false click beetle family, which is distinguished from the true click beetles (Elateridae) by certain morphological features. The genus name is derived from Aulus Vitellius, a Roman emperor who ruled briefly in 69 AD during the Year of the Four Emperors. As of current records, the genus has 14 observations documented on iNaturalist, though detailed biological information remains limited.
Xylobiini
Xylobiini is a tribe of false click beetles within the family Eucnemidae, subfamily Melasinae. Members of this tribe are associated with decaying wood habitats and are part of the diverse elateriform beetle fauna. The tribe was established by Reitter in 1911 and includes genera characterized by particular morphological features of the prosternal process and antennae. Xylobiini represents one of several tribes within the predominantly saproxylic subfamily Melasinae.
Xylophilus
Xylophilus is a genus of beetles in the family Eucnemidae, first described by Mannerheim in 1823. The genus belongs to the tribe Xylobiini within the subfamily Melasinae. Eucnemidae, commonly known as false click beetles, are a family of elateroid beetles characterized by larvae that develop in decaying wood. The genus name Xylophilus (from Greek xylon "wood" and philos "loving") reflects an association with woody substrates. The name Xylophilus is also used for a bacterial genus (Willems et al. 1987), but this taxon record refers to the beetle genus.
Xylophilus cylindriformis
Xylophilus cylindriformis is a species of false click beetle (family Eucnemidae) in the order Coleoptera. The species is known from a single observation record, indicating extreme rarity or limited detection in the field. Members of the genus Xylophilus are typically associated with dead or decaying wood, where larvae develop as saproxylic feeders. Adults are generally small to medium-sized beetles with elongated, cylindrical body forms.
