New species of Pseudonannolene Silvestri, 1895 from Brazilian limestone caves with comments on the potential distribution of the genus in South America (Spirostreptida: Pseudonannolenidae)

Abstract

Ten new species of Pseudonannolene Silvestri, 1895 are described from Brazilian limestone caves. The species are separated by the morphology of their gonopods and the processes of the first pair of legs of males. A pictorial identification key for the cave-dwelling species from Brazil is provided, besides comments on the distribution of the genus with a potential distribution map of Pseudonannolene and Epinannolene in South and Central America.

Annotated checklist of the millipede family Chelodesmidae Cook, 1895 from São Paulo state, Brazil (Diplopoda: Polydesmida)

“…This pattern is highly related to the species of Chelodesmidae from São Paulo, since most of the material was collected in farms and Research Stations (Schubart, 1944(Schubart, , 1960. It is important to highlight that these regions are also relevant for other millipedes groups in the state, especially for Paradoxosomatidae (Schubart, 1944(Schubart, , 1945aNguyen & Sierwald, 2013), Spirostreptida (Spirostreptidae and Pseudonannolenidae) (Krabbe, 1982;Jeekel, 2004;Iniesta & Ferreira, 2014), and Spirobolida (genus Rhinocricus) (Schubart, 1951c;Marek et al, 2003).…”

“…Aparentemente a espécie não apresenta características troglomórficas. A espécie foi observada em toda a caverna, associada a depósito de folhiço e guano carcaças de gafanhoto (Iniesta & Ferreira, 2014).…”

Pseudonannolene canastra sp. nov. (Diplopoda, Spirostreptida) – a new troglobitic millipede from the southwestern state of Minas Gerais, Brazil

“…Among the 60 species known, 49 were reported in Brazil and 25 among these occur in caves, while three are considered troglobitic (Iniesta and Ferreira 2014) i.e., the source population is exclusively subterranean (Trajano and Carvalho 2017). Most of the described species are in the states of Minas Gerais and São Paulo (Gallo and Bichuette 2019).…”

“…Most of the described species are in the states of Minas Gerais and São Paulo (Gallo and Bichuette 2019). In Brazil, the known troglobitic species include P. spelaea Iniesta & Ferreira, 2013, from Pará state, P. ambuatinga Ferreira, 2014, andP. lundi Iniesta &Ferreira, 2015; these last recorded in the Minas Gerais state.…”
