Attus niger (usually attributed to Sundevall, but in fact described by Walckenaer) is often regarded as a synonym of the present species, but this is doubtful and most likely incorrect. Aranea nigra Walckenaer, 1802 has been described from the Paris area as a black jumping spider with gray tarsi (note that the name is a junior primary homonym of Aranea nigra Petagna, 1787 and therefore the name was much later replaced by the name Sitticus walckenaeri Roewer, 1951). From the original description Aranea nigra Walckenaer, 1802 (subsequently placed in Attus: Attus niger (Walckenaer, 1802)) cannot be identified, the type material is lost, and the taxon is therefore a nomen dubium. This, however, has not prevented subsequent authors to use the name for any "blackish jumping spider". Sundevall was only the first of a number of authors who believed that they have found specimens of "Attus niger", and this led to a mixed and confusing concept of "Attus niger". It has to be stressed that the identity of the original Aranea nigra Walckenaer, 1802 is unclear and the name is a nomen dubium (see Breitling et al. 2016), and that all subsequent reports of Aranea nigra, Attus niger, Sitticus niger or Sitticus walckenaeri refer to a variety of dark or melanistic individuals of different species. Unfortunately, in the World Spider Catalog (accessed on September 30, 2016) the use of this name by Sundevall is regarded as a separate taxon ("Attus niger Sundevall, 1833"): however, this is incorrect, because Sundevall did not describe a new species, but simply used the name by Walckenaer for what he believed to be true Aranea nigra Walckenaer, 1802. Thus, Sundevall´s use of the name is a likely misidentification, but not the description of a new species.
