Revisão taxonômica dos Seirinae (Collembola, Entomobryi-Dae) em remanescentes urbanos de Mata Atlântica no Rio Grande do Norte - Brasil. 2019. 86f. Dissertação (Mestrado em Sistemática e Evolução) - Centro de Biociências, Universidade Federal do Rio Grande do Norte, Natal, 2019.https://repositorio.ufrn.br/jspui/handle/123456789/27294The northeastern region of Brazil, specifically Rio Grande do Norte state, holds several spots of Atlantic Rainforest with potentially large biological diversity, nevertheless still with a quite limited number of registers of springtails, particularly, of the subfamily Seirinae. At the same time, urban remnants of forested areas present great anthropic influence and the recognition of this diversity is the first step for their maintenance. This study had for main objective to perform a taxonomic study of the Seirinae species in such urban remnants, through the analysis of specimens deposited at the Collembola Collection of UFRN, collected between the July 2013 to July of 2017 with entomological aspirators and pitfall traps. Four species of Seira were redescribed in detail: S. paraibensis, S. arenicola, S. harena and S. brasiliana. S. dapeste, recently described from the study area was also included in the study. S. arenicola when compared with S. brasiliana, S. coroatensis and S. mataraquensis is dissimilar especially in number of macrochaetae on dorsal head as well as in the quantity of spines of the metatrocanteral organ. S. paraibensis was compared with another three species: S. harena, S. dapeste and S. diamantine signaling differences in the number of macrochaetae on “An” series of the cephalic chaetotaxy and quantity of spines on metatrocanteral organ. S. harena compared to S. dapeste, S. diamantinae and S. prodiga differs in the quantity of the macrochaetae of cephalic region, Abd I, Th III, pseudopores in the manubrial plate and thorns on metatrocanteral organ. S. potiguara was identified as a junior synonym of S. brasiliana and it was compared with S. arenicola, S. jiboiensis e S. tinguira, and all species differ in number of the macrochaetae of Abd II and ventral tube chaetotaxy. This study contributes with the increase of knowledge of Entomobryoidea fauna from Northeastern region of Brazil, producing metadata which can be used for maintenance of Parque Estadual Dunas do Natal.Acesso AbertoEntomobryinaeEntomobryoideaRiqueza taxonômicaSeiriniSeiramasterThesisCNPQ::CIENCIAS BIOLOGICAS
