Mycotretus
Mycotretus is a large American genus in the pleasing fungus beetle family (Erotylidae). They are small, oval beetles, and often very colorful and boldly patterned in yellowish, orange-red to chestnut-brown, and black hues; historically, they were popular with insect collectors. Among its family, this genus is placed in subfamily Tritominae, or – in taxonomic arrangements that prefer a more comprehensive subfamily Erotylinae – in tribe Tritomini of the Erotylinae.
These beetles are found throughout the Neotropics except on high mountain ranges. Some isolated records from temperate North America presumably refer to introduced specimens. One species (M.nigromanicatus) ranges as far north as the Chiricahua Mountains of Arizona, USA, while in the south of the genus' range, several species are found in Paraguay and northern Argentina. While some species, such as M.ornatus, M.pygmaeus and M.scitulus, occur almost across the entire range of the genus, many are restricted to a single range of hills or to one area bordered by large rivers, with Mexico and the Amazon Basin having the highest diversity of Mycotretus. Like some of their relatives, they do not eat mainly polypores (shelf fungi) as most pleasing fungus beetles do, but prefer gilled Agaricales fungi; unlike in the close relative Pselaphacus, larvae of Mycotretus species feed individually and do not receive parental care.
