Abstract in Portuguese
Uma revisão taxonômica e análise cladística do gênero Pseudonannolene Silvestri, 1895 é apresentada. A análise compreende 53 terminais como grupo-interno e 10 como grupo-externo. 91 caracteres morfológicos foram codificados. Três sinapomorfias em comum suportam o monofiletismo de Pseudonannolene: presença de sutura longitudinal no promentum, conexão entre as bandas do pênis e ramo interno circundando telopodito; e duas transformações homoplásticas: collum densamente estriado e cerdas distribuídas até o ápice do processo pré-femoral do primeiro par de pernas dos machos. Pseudonannolene é recuperado como grupo-irmão de Epinannolene Brölemann, 1903 em Pseudonannoleninae. O clado é suportado por duas sinapomorfias: processo pré-femoral desenvolvido e tarso alongado do segundo par de pernas dos machos; e uma transformação homoplástica: telopodito estreito. Grupos mais inclusivos do gênero são detalhados e discutidos. Espécies de Pseudonannolene apresentam ampla distribuição ocupando a região Neotropical. Como revisto aqui, o gênero compreende 56 espécies, incluindo oito novas espécies. P. brevis Silvestri, 1902 e P. rugosetta Silvestri, 1897 são consideradas species inquirendae. Neótipo de P. alegrensis Silvestri, 1897 é aqui proposto e macho descrito pela primeira vez. As seguintes espécies são sinonimizadas: P. canastra Gallo & Bichuette, 2020 e P. saguassu Iniesta & Ferreira, 2013 com P. ambuatinga Iniesta & Ferreira, 2013; P. marconii Iniesta & Ferreira, 2013 com P. longicornis (Porat, 1888); P. chaimowiczi Fontanetti, 1996, P. gogo Iniesta & Ferreira, 2013, P. rosineii Iniesta & Ferreira, 2014, P. taboa Iniesta & Ferreira, 2014 e P. longíssima Iniesta & Ferreira, 2014 com P. microzoporus Mauriès, 1987; P. tricolor gracilis Brölemann, 1902 e P. tricolor rugosus Schubart, 1945 com P. tricolor Brölemann, 1902; P. auguralis Silvestri, 1902 com P. rocana Silvestri, 1902; e P. abbreviata Silvestri, 1902 com P. typica Silvestri, 1895. P. inops Brölemann, 1929 como novo status a partir de P. bovei inops. Fêmeas são descritas pela primeira vez para P. albiventris Schubart, 1952, P. borelli Silvestri, 1895, P. bovei Silvestri, 1895, P. buhrnheimi Schubart, 1960, P. curtipes Schubart, 1960, P. halophila Schubart, 1949, P. leucocephalus Schubart, 1944, P. leucomelas Schubart, 1947, P. marítima Schubart, 1949, P. meridionalis Silvestri, 1902, P. occidentalis Schubart, 1958, P. ophiiulus Schubart, 1944, P. parvula Silvestri, 1902, P. paulista Brölemann, 1902, P. pusilla Silvestri, 1895, P. robsoni Iniesta & Ferreira, 2014, P. rocana Silvestri, 1902, P. sebastianus Brölemann, 1902, P. segmentata Silvestri, 1895, P. silvestres Schubart, 1944, P. strinatii Mauriès, 1974, P. tricolor Brölemann, 1902, P. typica Silvestri, 1895, P. urbica Schubart, 1945 e P. xavieri Iniesta & Ferreira, 2014. Uma chave para as espécies de Pseudonannolene e mapas de distribuição são fornecidos.

Abstract in English
A taxonomic review and cladistic analysis of the millipede genus Pseudonannolene Silvestri, 1895 is presented. The analysis is based on a dataset including 53 species of the genus as ingroup and 10 species as outgroup. 91 morphological characters were scored for the analysis. Three common synapomorphies support the monophyly of Pseudonannolene: presence of longitudinal suture on promentum, connection between the bands of penis and internal branch surrounding telopodite; and two homoplastic transformation: collum densely striate and setae located at the apex of prefemoral process of the first legpair of males. Pseudonannolene is recovered as adelphotaxon of Epinannolene Brölemann, 1903, comprising the subfamily Pseudonannoleninae. This clade is supported by two synapomorphies: well-developed prefemoral process and elongated tarsus of the second legpair of males; and one homoplastic transformation: narrow telopodite. Some internal clades within the genus are detailed and discussed. As revised here, the genus comprises 56 species, including eight undescribed species. P. brevis Silvestri, 1902 and P. rugosetta Silvestri, 1897 are considered species inquirendae. Neotype of P. alegrensis Silvestri, 1897 is herein proposed and male described for the first time. The following taxa are synonymized: P. canastra Gallo & Bichuette, 2020 and P. saguassu Iniesta & Ferreira, 2013 with P. ambuatinga Iniesta & Ferreira, 2013; P. marconii Iniesta & Ferreira, 2014 with P. longicornis (Porat, 1888); P. chaimowiczi Fontanetti, 1996, P. gogo Iniesta & Ferreira, 2013, P. rosineii Iniesta & Ferreira, 2014, P. taboa Iniesta & Ferreira, 2014 and P. longissimi Iniesta & Ferreira, 2014 with P. microzoporus Mauriès, 1987; P. tricolor gracilis Brölemann, 1902 and P. tricolor rugosus Schubart, 1945 with P. tricolor Brölemann, 1902; P. auguralis Silvestri, 1902 with P. rocana Silvestri, 1902; and P. abbreviate Silvestri, 1902 with P. typical Silvestri, 1895. P. inops Brölemann, 1929 as new status from P. bovei inops. Females are described for the first time for P. albiventris Schubart, 1952, P. Borelli Silvestri, 1895, P. bovei Silvestri, 1895, P. buhrnheimi Schubart, 1960, P. curtipes Schubart, 1960, P. halophile Schubart, 1949, P. leucocephalus Schubart, 1944, P. leucomelas Schubart, 1947, P. maritima Schubart, 1949, P. meridionalis Silvestri, 1902, P. occidentalis Schubart, 1958, P. ophiiulus Schubart, 1944, P. parvula Silvestri, 1902, P. paulista Brölemann, 1902, P. pusilla Silvestri, 1895, P. robsoni> Iniesta & Ferreira, 2014, P. rocana Silvestri, 1902, P. sebastianus Brölemann, 1902, P. segmentata Silvestri, 1895, P. silvestris Schubart, 1944, P. strinatii Mauriès, 1974, P. tricolor Brölemann, 1902, P. typical Silvestri, 1895, P. urbica Schubart, 1945 and P. xavieri Iniesta & Ferreira, 2014. A key to species of Pseudonannolene and distribution maps are provided.
