Remarks.Campiglossa sororcula was previously placed in the genus Dioxyna Frey, 1945. However, a study on DNA barcoding by Smit et al. (2013) showed that this genus was placed within the genus Campiglossa and was recently formally synonymized by Han & Ro (2019). This species is distributed in tropical and subtropical regions. Larvae attack flower heads of Bidens sp. and other weeds (Kapoor 2005; Starr & Starr 2011). This fly can be found in a variety of habitats from natural to urban areas (Kapoor 2005) and is the most common and widespread tephritid in Madeira Island (Smit 2006). Our records from Porto Santo are the first reported for the island.
