Abstract
AbstractWe herein present the first reliable record ofLepidosirafrom Neotropical Region.Lepidosira neotropicalissp. n. from Brazil is described and illustrated in detail, including its complete mitochondrial genome. We perform a Bayesian phylogenetic analysis to place the new species within the Entomobryidae, and at the same time to test previous contrasting hypotheses onLepidosiraposition within the Entomobryinae versus Seirinae for the first time. Phylogenetic analyses were based on one mitochondrial and two nuclear genes, Cytochrome Oxidase subunit I, 18S ribosomal RNA and 28S ribosomal RNA, respectively.Lepidosira neotropicalissp. n. resemblesL. sundanaYoshii and Suhardjono andL. nigropunctata(Nguyen) in dorsal chaetotaxy of abdominal segments I and II, but differs from all other species by the combination of head (dorsally and ventrally) and dorsal trunk chaetotaxy, plus empodial complex morphology. Our phylogenetic analyses support the placement ofLepidosirawithin Entomobryinae, as the sister group ofLepidocyrtoides. Overall, our revision enables a more objective diagnosis toLepidosiraand suggests that the genus is in need of a full revision due to its variable morphology, and lack of data needed to evaluate its monophyly. Finally, we provide an identification key for Neotropical genera of Entomobryinae.
