What is "paederinae"

The Paederinae are a subfamily of the Staphylinidae, rove beetles. The Paederinae include two tribes, Paederini and Pinophilini.

Three of the genera of a subtribe of the Paederini are associated with a skin irritation called Paederus dermatitis, due to a potent vesicant in their haemolymph. This irritant, pederin, is highly toxic, more potent than cobra venom. Thirty-six genera and 436 species are found in North America, generally in damp places, under logs, in caves and ant nests, in litter, or on foliage. Major genera include Rugilus.
