For the cladistic approach, 91 morphological characters were scored for 53 terminals as the ingroup and 10 as the outgroup. Three synapomorphies support the monophyly of the genus: presence of a longitudinal suture on the promentum, penial bases partially fused, and the internal branch of the gonopods surrounding the telopodite; and two homoplastic transformations: the lateral lobe of the collum densely striated and setae present up to the apical portion of the prefemoral process on the first leg-pair of males. The genus <em>Pseudonannolene</em> is recovered as sister-group of <em>Epinannolene</em> Brölemann, 1903 (Pseudonannoleninae). A total of 226 occurrence points were recorded for <em>Pseudonannolene</em>, with the majority of records from the Chacoan subregion, composed by Araucaria Forest, Atlantic, and Parana Forest provinces. The biogeographical searches using the Geographically explicit Event Model recovered two biogeographic reconstructions (cost of 79 000), with the vicariance events occurring more frequently in the deep clades, whereas sympatry and points of sympatry occurred in more inclusive clades. The first reconstruction recovered four vicariances, 13 sympatries, 4 points of sympatry, and 21&nbsp;founder events, and the second reconstruction recovered four vicariances, 12–13 sympatries, 4–5&nbsp;points of sympatry, and 21 founder events. The genus <em>Pseudonannolene</em> comprises 56 species, including 8 new species herein described: <em>P.&nbsp;alata</em> sp.&nbsp;nov., <em>P.&nbsp;aurea</em> sp.&nbsp;nov., <em>P.&nbsp;bucculenta</em> sp.&nbsp;nov<em>.</em>,<em> P.&nbsp;curvata</em> sp.&nbsp;nov., <em>P.&nbsp;granulata</em> sp.&nbsp;nov., <em>P.&nbsp;insularis</em> sp.&nbsp;nov., <em>P.&nbsp;morettii</em> sp.&nbsp;nov., and <em>P.&nbsp;nicolau</em> sp.&nbsp;nov.; <em>P.&nbsp;brevis</em> Silvestri, 1902 and <em>P.&nbsp;rugosetta</em> Silvestri, 1897 are regarded as species inquirendae; a neotype of <em>P.&nbsp;alegrensis</em> Silvestri, 1897 is here proposed with male described for the first time. The following taxa are synonymized: <em>P.&nbsp;canastra</em> Gallo &amp; Bichuette, 2020 and <em>P.&nbsp;saguassu</em> Iniesta &amp; Ferreira, 2013 with <em>P.&nbsp;ambuatinga</em> Iniesta &amp; Ferreira, 2013;<em> P.&nbsp;marconii</em> Iniesta &amp; Ferreira, 2013 with <em>P.&nbsp;longicornis</em> (Porat, 1888); <em>P.&nbsp;chaimowiczi</em> Fontanetti, 1996, <em>P.&nbsp;gogo</em> Iniesta &amp; Ferreira, 2013, <em>P.&nbsp;rosineii</em> Iniesta &amp; Ferreira, 2014, <em>P.&nbsp;taboa</em> Iniesta &amp; Ferreira, 2014, and <em>P.&nbsp;longissima</em> Iniesta &amp; Ferreira, 2014 with <em>P.&nbsp;microzoporus</em> Mauriès, 1987; <em>P.&nbsp;tricolor gracilis</em> Brölemann, 1902 and <em>P.&nbsp;tricolor rugosus</em> Schubart, 1945 with <em>P.&nbsp;tricolor</em> Brölemann, 1902; <em>P.&nbsp;auguralis</em> Silvestri, 1902 with <em>P.&nbsp;rocana</em> Silvestri, 1902; and <em>P.&nbsp;abbreviata</em> Silvestri, 1902 with <em>P.&nbsp;typica</em> Silvestri, 1895. <em>P.&nbsp;inops</em> Brölemann, 1929 is proposed here as new status from <em>P.&nbsp;bovei inops</em>. A dichotomous identification key is presented to facilitate the species identification.</p>}, number={1}, journal={European Journal of Taxonomy}, author={Iniesta, Luiz Felipe Moretti and Bouzan, Rodrigo Salvador and Brescovit, Antonio Domingos}, year={2023}, month={Apr.}, pages={1–312} }
