Ecitoxenidia
Ecitoxenidia is a genus of rove beetles (Staphylinidae) established by Wasmann in 1909. The genus contains five described species distributed in North America. Based on its tribal placement in Lomechusini, members are likely myrmecophiles (ant-associated), though direct host records are not documented in available sources.
Metopiasini
Metopiasini is a tribe of minute rove beetles (Staphylinidae: Pselaphinae) comprising nine genera, eight of which are restricted to the Neotropical region. The tribe is suspected to be myrmecophilous, though direct ant associations remain unconfirmed. Members exhibit morphological traits consistent with subterranean or litter-dwelling habits, including reduced eyes and elongated appendages. The genus Metopiellus, distributed from Colombia to Argentina, was recently recorded from Ecuador for the first time with two new species described from Amazonian and montane cloud forest habitats.
