Description
Summary:<i>Encarsia protransvena</i> (Hymenoptera: Aphelinidae) is recorded here for the first time in Italy as a parasitoid of the whitefly <i>Singhiella simplex</i> (Hemiptera: Aleyrodidae), one of the most invasive alien pests of exotic <i>Ficus</i> species. <i>Singhiella simplex,</i> originating from the Oriental region, has established a global presence. Monitoring of the whitefly and its parasitoids was conducted in the southern areas of Italy, providing crucial insights into their distribution and interactions. The taxonomic identity of <i>E. protransvena</i>, was confirmed by scrutiny of morphological and molecular taxonomic characters. At the time of writing, we also obtained some specimens of <i>Encarsia hispida</i> from the host collected in Campania. We reserve the right to provide bio-ethological information on the species in the future. Comprehensive illustrations and diagnostic features are provided for the host and the parasitoids. An identification key is included for all <i>Encarsia</i> species associated with <i>S. simplex</i>, which provides a valuable tool to distinguish these aphelinid wasps for future research and applications in biological control programs.
