Trioza dispar Low 1878

Trioza dispar Löw, 1878 Notes Together with T. foersteri Meyer-Dür, 1871, T. megacerca, T. proxima and T. tatrensis Klimaszewski, 1965, T. dispar forms a group of morphologically and biologically similar species and the records of T. dispar published before the revision of the group by Burckhardt (1983) should be re-examined (see also Lauterer and Malenovský (2002)). This also applies to the only record of T. dispar from Bulgaria (Rila Mts.) by Joakimov (1909), as it could be, for example, T. megacerca or T. proxima, which have been confirmed more recently from this country. As the specimens were not available for revision (Pramatarova et al. 2023), we consider the occurrence of T. dispar in Bulgaria to be doubtful.
