Remarks

This species can be easily distinguished from other species by the shorter ribbon-like setae and forked setae, similar to another genus Rhadinoscelidia . We assigned this new species to Loboscelidia because it has the developed wing venation; however, other characteristics (e.g., long scape with dense erect or suberect setae; cervical expansion with shorter ribbon-like setae; pronotum with forked erect setae; and tibiae without flanges) are rather similar to those of Rhadinoscelida.
