NEW PHREODRILIDAE (ANNELIDA: CliTELLATA) FROM TASMANIAN ESTUARIES
A new species of Phreodrilidae from Macquarie Harbour, Tasmania is described. Astacopsidrilus ostiensis sp. nov. is unique in possessing the combination of long, tightly folded atria, modified spermarhecal chaetae and ventral chaetae that are almost simple pointed. These are the first phreodrilids to be recorded from estuarine or intertidal habitats, other than two species collected from beache...
متن کاملTwo species of Naididae (Annelida, Clitellata) from southern Tibet, China
One new species of Naidinae (Oligochaeta, Naididae), Naisbadia sp. n. and one new record species from China, Tubifexmontanus Kowalewski, 1919 (Tubificinae) are found in southern Tibet. The new species is distinguished from congeners by its large area of reddish brown pigment in the anterior segments I-VIII, serrate hairs, pectinate needles with 1-2 intermediate teeth, ventral chaetae partly wit...

متن کاملMolecular phylogeny, biogeography, and habitat preference evolution of marsupials.
Marsupials exhibit great diversity in ecology and morphology. However, compared with their sister group, the placental mammals, our understanding of many aspects of marsupial evolution remains limited. We use 101 mitochondrial genomes and data from 26 nuclear loci to reconstruct a dated phylogeny including 97% of extant genera and 58% of modern marsupial species. This tree allows us to analyze ...
متن کاملThe systematic position of Opistocystidae (Annelida, Clitellata) revealed by DNA data.
Opistocystidae Cernosvitov, 1936 is a largely Neotropical oligochaete taxon containing seven species. Its familial status has never been formally challenged, although possible close relationships with Naididae and Phreodrilidae have been noted. Mitochondrial 12S and 16S rDNA, and nuclear 18S rDNA, of a range of aquatic oligochaete taxa, including Trieminentia corderoi (Opistocystidae), were ana...
