Abstract
The complete mitochondrial genome of Whitmania laevis is 14,442 bp in length and contains 37 genes including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes. The almost-complete mitochondrial genome of Whitmania acranulata , consisting of 13,494 bp, contains 35 genes including 13 PCGs, 20 tRNA genes, and two rRNA genes. COI phylogenetic analyses showed that the samples reported in GenBank and analysed as Hirudo nipponia KC667144, Hirudinaria manillensis KC688268 and Erpobdella octoculata KC688270 are not the named species and they should belong to Whitmania . We compared and analyzed the characteristics of nucleotide composition, codon usage, and secondary structures of 22 tRNAs and two rRNAs from Whitmania taxa. Moreover, we analyzed phylogenetic relationships of Annelida using maximum likelihood (ML) and Bayesian inference (BI) methods, based on 11 mitochondrial genes. Our results reveal that W. laevis has a close relationship with W. pigra .
期刊介绍：
The Belgian Journal of Zoology is an open access journal publishing high-quality research papers in English that are original, of broad interest and hypothesis-driven. Manuscripts on all aspects of zoology are considered, including anatomy, behaviour, developmental biology, ecology, evolution, genetics, genomics and physiology. Manuscripts on veterinary topics are outside of the journal’s scope. The Belgian Journal of Zoology also welcomes reviews, especially from complex or poorly understood research fields in zoology. The Belgian Journal of Zoology does no longer publish purely taxonomic papers. Surveys and reports on novel or invasive animal species for Belgium are considered only if sufficient new biological or biogeographic information is included.
