Lachnophorini
Lachnophorini is a tribe of ground beetles (family Carabidae) comprising approximately 18 genera and more than 190 described species. The tribe exhibits remarkable morphological diversity and divergent ecological habits, with most species being very small (less than 3.74 mm in adult body length). A 2014 taxonomic synopsis added a new genus (Peruphorticus) and 24 new species, significantly expanding known diversity. The tribe shows distinct biogeographic patterns, with Neotropical species in the Amazon Basin and Middle and South America, and additional representatives in the Paleotropics and Australia. Recent research indicates local ecological adaptation and morphological convergence related to habitat use within the Amazon Basin radiation.
