Taxonomic notes
In the description of the genus Sparassus, Walckenaer (1805: 40) just listed Sparassus argelasius without a description (nomen nudum) along with the following nominal species: S. samaragdulus (Fabricius, 1793) , S. pallens (Fabricius, 1794) , S. roseus (Clerck, 1757) and S. ornatus (Walckenaer, 1802) [for more details see Jäger (1999: 3)]. One year later ( Walckenaer 1806: 146, table 2) he published a description and illustration of a male under the name Sparassus argelasius , which was a misidentification and was later transferred to the genus Olios . Walckenaer’s original description of Sparassus was actually based on species of the previously established genus Micrommata Latreille, 1804 and a single male of Olios argelasius . Latreille (1818) examining two female specimens from Spain tried to describe the female of Walckenaer’s species, “ Sparassus argelasius ”, and transferred it to Micrommata (sub Micromata argelasia ), but he failed to identify it correctly. This misidentification was pointed out later by Simon (1903: 1025), who described his new genus Eusparassus and cited Latreille’s description and indicated the type species as E. argelasius Latreille. But the Latreille misidentification was based on Walckenaer (1805) and the species name was already occupied by Olios argelasius (sub Sparassus ). Later, Simon (1932: 890) realized this confusion when he described and illustrated O. argelasius (Walckenaer) and proposed E. dufouri as a new replacement name (nomen novum) to substitute the previously established name E. argelasius . Simon noted that “the species described under the name Sparassus argelasius Latreille (in Simon 1875: 334) must take the new name (nom. nov.) as Eusparassus dufouri ”. Before proposing the genus Eusparassus, Simon in his publications (1875: 334; 1880: 290) used the nominal species “ Sparassus argelasius ” for describing E. dufouri . In the literature, Sparassus itself was used to record not only different species but also different generic taxa including Micrommata , Olios and Eusparassus .
Neotype designation
According to all the facts noted, Simon (1932) did not designate any name-bearing type specimen subsequently while referring to Latreille (1818). According to Article 72.4.2 of the International Commission on Zoological Nomenclature, when a new nominal species-group taxon ( E. dufouri ) is based on a published misidentification by an earlier author ( M. argelasia Lat. ), the type series consists of the specimens that had been misidentified. No material of Latreille can be traced in MNHN and it is generally understood that none exists. Consequently, it is necessary to designate a neotype for E. dufouri at this time to establish its identity, define the nominal taxon objectively and avoid taxonomic confusion with similar and closely related species in the Iberian Peninsula (i.e. E. levantinus Urones, 2006 ), in Northern Africa [i.e. E. oraniensis (Lucas, 1846) ] and in the eastern Mediterranean (i.e. E. walckenaeri ). There are two forms in the Iberian Peninsula, E. dufouri of uncertain identity, and E. levantinus , which was described by Urones (2006). The latter species is distributed in eastern and southern Spain but is replaced by E. dufouri in the western Iberian Peninsula. Accordingly, a neotype is designated for E. dufouri from the western Iberian Peninsula on the border of Portugal and Spain, in Montalvão. Based on the distribution map presented by Urones (2006) and also using the distribution records of the present study, type locality is selected to be as far as possible from the distribution range of E. levantinus . Specimens were freshly collected and DNA samples are available.
Known geographical distribution and habitat
Western Iberian Peninsula in Spain and Portugal, mostly under stones; under old tree bark in the southeast of Portugal (Barrancos Valley), including in Eucalyptus trees. (S. Henriques, personal observation).
Doubtful record
Simon (1932: 890) stated that the single report of the species from France (Pyrenees-Orientales) was actually collected in a shipment from Spain, Iberia.
