This species is characterized by the absence of the cu-a vein and having a submedially curved medial vein, characters shared with Loboscelidia cinnamonea  . It can be distinguished from Loboscelidia cinnamonea  by Rs 3 × as long or longer than R, scape 3 × or shorter as long as broad, scrobal sulcus present and the fore and midtibiae without flanges.
