The Oxyporinae are a subfamily of the Staphylinidae discovered in 1839 by Erichson.[1] One genus, Oxyporus Fabricius, with 132 species, is found worldwide.[2]
All Oxyporinae have prominent mandibles. Their apical labial palpomeres are very large and strongly securiform. Their tarsi, like most Staphylinidae, are 5-5-5.
Most Oxyporinae are fungivores. Their whole lifecycle involves fungi, as females construct egg-laying chambers in fungi and reproduce in them. Thus, most scientists inspect mushrooms and fleshy fungi to find these creatures.
