“…The genus Neurigona Rondani, 1856 belongs to the subfamily Neurigoninae within Dolichopodidae . They usually have non-metallic yellow coloration on much of the thorax, legs, and abdomen, and can be separated from other Dolichopodidae genera by the following features: proboscis with a pair of long and pale ventral hairs; posterior mesonotum distinctly flattened; legs slender and long, and anterior preapical setae on mid and hind femora absent; sternite 5 sometimes with a ventral projection in males; fore tarsomere 1 usually elongated; vein M gently or strongly bent apically and convergent with R 4+5 ; surstylus divided into dorsal and ventral lobes; cercus with digitiform internal median projection ( Naglis 2003 ; Kazerani et al 2022 ). Adults of most species are regularly observed on tree trunks where the males also exhibit their courtship behavior, sometimes in large numbers ( Parent 1938 ).…”
