G. R. Graves, 1993,
Description based on a specimen purchased in Bogotá, Colombia, in 1909. This was thought to be an example of what had been named Neolesbia nehrkorni, type specimen of which had been lost; for a long time, latter was considered by most authorities to be a hybrid between Aglaiocercus kingii and probably Thalurania (T. furcata or T. colombica), although some argued that it was more likely a valid and probably extinct species related to H. regalis. Recent molecular study#R indicates that it is an independent species, belonging alongside Aglaiocercus and Taphrolesbia griseiventris; the generic affiliation thus probably needs to be changed. Monotypic.
Not known. Specimen suspected to have been collected in E Andes of Colombia, possibly in submontane forest towards Magdalena Valley.
