Tritoma is a genus of beetles in the family Erotylidae, the pleasing fungus beetles. It is distributed worldwide, mainly in the Old World. [2] There are over 100 species. [2]

Contents

Some species consume euagaric mushrooms, staying concealed amidst the gills as they feed. [3] Some feed on mushrooms growing from dead trees, as well as mycorrhizae on living roots. [4] One of the most common pleasing fungus beetles in Europe, T. bipustulata, is a black beetle with red spots which engages in autohaemorrhaging as a defensive behavior. [5]

Molecular analysis suggests that Tritoma is paraphyletic, and might be best treated as two separate genera. [3]

Erotylidae Family of beetles

Erotylidae, or the pleasing fungus beetles, is a family of beetles containing over 100 genera. In the present circumscription, it contains 6 tribes and 10 subfamilies. In other words, the narrowly circumscribed Erotylidae correspond to the subfamily Erotylinae in the definition sensu lato. There are doubts on the monophyly of lower ranked taxa within Erotylidae, with further phylogenetic studies requiring better sampling and studies of unexplored character sets, for example the metendosternite and penile flagellum, which are generally lacking detailed morphological studies within the Coleoptera literature.
