[I.C.Z.N., Opinion 2347, Case 3589 (2014) use of Hemerodromia Meigen, 1822 preserved, excluding all type-species including in Hemerodromia Meigen, 1822 before Tachydromia oratoria Fallén, 1815 , by Rondani, 1856]; Câmara et al. 2014: 27 (description); Câmara et al. 2015: 18 (description); Câmara et al. 2016: 66 (revision); Plant 2020: 12 (description).

Diagnosis. Head dorsoventrally flattened (but spherical in H. brevicercata ); eyes with upper ommatidia larger than lower ommatidia (especially in males); postpedicel lanceolate, stylus not longer than postpedicel, proximal article poorly differentiated; thorax with only well-developed notopleural and sometimes scutellar setae; acrostichal and dorsocentral setae usually present but minute; wing with bifurcated R 4+5 and M 1 and M 2 present (M 2 absent in H. bradleyi sp. nov.); cells bm and dm fused; cell cua absent; subcostal vein fused proximally with costal vein, separated at level of radio-cubital node; h vein absent; fore femur with 2 rows of tiny black denticles, with adjacent antero- and posteroventral rows of setae more developed ( Câmara et al. 2016).
