New records of the genus Temnostoma Le Peletier & Serville, 1828 (Diptera: Syrphidae) in the NW Balkans
The genus Temnostoma comprises saproxylic hoverflies whose larvae develop by boring into wet, decaying wood, where they feed on microorganisms. Records of these species in the northwestern Balkans are sparse in the literature and nearly absent from openaccess databases. To enhance knowledge of their distribution in the region, we present new records of four Temnostoma species from Croatia, Bosnia and Herzegovina, and Serbia. Three species were recorded in all three countries, while T. apiforme was found exclusively in Croatia. This discovery marks not only the first record of this species in the country but also the first for the entire Balkan Peninsula. Furthermore, Temnostomameridionale was documented in Bosnia and Herzegovina for the first time. Given thatthese hoverflies are large and visually striking, we hope this study will inspire interestamong citizen scientists and encourage future contributions to the documentation ofthis genus in the region.
