New records and distribution of the tiger fly Eristalinus (Eristalodes) taeniops (Wiedemann, 1818) (Diptera: Syrphidae) in Paraguay

Abstract

The exotic species Eristalinus taeniops is recorded for the first time in Paraguay from specimens collected in the cities of Asunción (Capital District) and Hernandarias (Alto Paraná Department). In addition, the records of the species on the iNaturalist citizen science platform were reviewed, confirming its presence in San Lorenzo, Luque and Fernando de la Mora (Central Department). The impact that the presence of this foreign species could generate in the country’s natural ecosystems is briefly discussed.
