The species from the genus Isodontia Patton, 1880 are distributed mainly in Neotropical and Oriental Regions ( Bohart & Menke 1976). Two native species of the genus are known from Europe - I. paludosa (Rossi, 1790) and I. splendidula (A. Costa, 1858), both presented in Bulgaria ( Pulawski 2017, Guéorguiev & Ljubomirov 2009 e.g.). I. mexicana , a North American species, was established in France in the early 1960s and recently is east and north-eastwards spreading in Europe ( Ćetković et al. 2012). To date, the known range of the species in Europe include France, Italy, Spain, Switzerland, Slovenia, Croatia, Germany, Hungary, Austria, Netherlands, Serbia, Belgium, Czech Republic, Slovakia, Crimea, Greece and Great Britain ( Semelbauer 2015, Pulawski 2017).
