Harlequin toads (Atelopus) are distributed over a wide range in the Amazon Rainforest, mostly associated with streamlets in dense ombrophilous forests in lowland and sub-montane regions. Atelopus hoogmoedi Lescure, 1974a was considered as bearing full species status by Lötters et al. (2005), although until that moment this species had been assigned to a subspecies of A. pulcher (Boulenger, 1882) (Lescure 1974a, 1976) or of A. spumarius Cope, 1871 (Lescure et al. 1980; Lescure Marty 2000; Lötters et al. 2002). More recently, Noonan Gaucher (2005) subscribed to Lötters et al. (2005)'s statement that A. s. hoogmoedi should belong to a distinctive species (A. hoogmoedi), based on phylogeographic evidence. The species' range is currently restricted to the Guiana Shield of French Guiana, Suriname, Guyana, and in adjacent regions of northern Brazil (Lötters et al. 2005).
小丑蟾蜍（Atelopus属）分布于亚马逊雨林的广泛区域，大多与低地和亚山地地区茂密的雨林中的小溪流有关。1974年，Lescure将Atelopus hoogmoedi认定为一个独立物种，Lötters等人（2005年）也认同这一观点，不过在此之前，该物种一直被归为A. pulcher（Boulenger，1882年）（Lescure，1974年a，1976年）或A. spumarius Cope，1871年（Lescure等人，1980年；Lescure Marty，2000年；Lötters等人，2002年）的一个亚种。最近，Noonan和Gaucher（2005年）根据系统地理学证据，认同了Lötters等人（2005年）的观点，即A. s. hoogmoedi应属于一个独特的物种（A. hoogmoedi）。该物种目前的分布范围仅限于法属圭亚那、苏里南、圭亚那的圭亚那地盾以及巴西北部的相邻地区（Lötters等人，2005年）。
