Diversity and phylogeny of south-east Queensland Bathynellacea

摘要: The crustacean order Bathynellacea is amongst the most diverse and widespread groups of subterranean aquatic fauna (stygofauna) in Australia. Interest diversity biogeography Australian has grown markedly recent years. However, relatively little information relating to this group emerged from Queensland. aim study was investigate bathynellacean phylogeny south-east Relationships between Queensland their continental relatives were evaluated through analysis combined mitochondrial nuclear DNA sequence data. Bathynellaceans collected alluvial groundwater systems three catchments This revealed a with complex evolutionary relationships related elsewhere Queensland, on wider continent. multifamily assemblage here likely represent several new species, at least one genus within Parabathynellidae. These taxa have restricted geographic distributions. Interestingly, appeared be distantly north-east counterparts. Although it not possible determine generic identities closest relatives, Parabathynellidae appear closely affiliated southern eastern lineages. Together previous survey data, findings suggest that there considerable across region. Further assessment stygofauna distributions necessary understand biological implications significant use development
