Project description:The genus Boehmiella was initially described as a member of the family Trichostrongylidae. Subsequently, it was assigned to the subfamily Haemonchinae in the family Haemonchidae. We analyzed parasites of spiny tree-rats, Mesomys hispidus, collected in the Amazon rainforest, which were identified as B. wilsoni based on integrative taxonomy. Using morphology, morphometry, and scanning electron microscopy (SEM), we added new data to the original description of the species. We also inferred phylogenetic hypotheses for its relationships within the Trichostrongylina, based on partial nuclear 18S and 28S rRNA genes, through Maximum Likelihood and Bayesian analyses. In conclusion, B. wilsoni does not belong to the family Haemonchidae, nor is it closely related to any other trichostrongylin family, and therefore, we propose the establishment of a new family, Boehmiellidae fam. nov., to which the genus Boehmiella is allocated.
Project description:Chaenodraco wilsoni, a species of Channichthyidae, inhabits in southern ocean. The total length of complete mitochondrial genome of C. wilsoni is 17,432?bp, which encoded 37 genes. Similar to most Antarctic fishes, the ND6/tRNA (glu) translocation and an additional non-coding region linked with ND6 have also occurred in C. wilsoni. The ML tree supports that C. wilsoni has closer relationship with Chionodraco species. Our research will provide more molecular biology information about C. wilsoni and deepen the understanding of Antarctic fishes.
