A64D48606526FFDCFD9A83B2FB436F16.taxon	discussion	Remarks Scelolabes is similar to Hoplopeza by the antenna inserted above the mid-height of the head, wing with anal lobe not developed and Rs vein very short, arising near the apex of bm cell. Both genera are different by apical strong setae in hind tibia present in Hoplopeza, vs weak or absent in Scelolabes, right surstylus with bifid apex, chela-like in Scelolabes, vs simple in Hoplopeza, and tergite 10 absent in females of Scelolabes, while it is present in Hoplopeza. Additionally, in Scelolabes the acrostichal setae are always multiserial, while in Hoplopeza they may be either uniserial or multiserial.	en	Barros, Luana Machado, Freitas-Silva, Rafael Augusto Pinheiro de, Ale-Rocha, Rosaly (2023): Revision of Neotropical Scelolabes Philippi (Diptera, Hybotidae, Ocydromiinae): two new species and a proposal of delimitation.

A64D4860652CFFD4FD8C8380FC366B7B.taxon	discussion	Remarks Scelolabes bivittatus is similar to S. verasilvae sp. nov. by the scutum with a black intra-alar stripe and the abdominal tergites weakly sclerotized anteriorly. In addition, S. bivittatus has the scape and pedicel yellow and the black stripes on the scutum are restricted to intra-alar region, whereas in S. verasilvae the scape and pedicel are brown and the darker marks on the scutum are broader and occupy the dorsocentral region. Also, in S. bivittatus the hind femur is strongly swollen, whereas in S. verasilvae the hind femur is only slightly swollen.	en	Barros, Luana Machado, Freitas-Silva, Rafael Augusto Pinheiro de, Ale-Rocha, Rosaly (2023): Revision of Neotropical Scelolabes Philippi (Diptera, Hybotidae, Ocydromiinae): two new species and a proposal of delimitation.
