The complete mitochondrial genome of the long-tailed mole: Scaptonyx fusicaudus (Eulipotyphla, Talpidae)

Abstract

The long-tailed mole (Scaptonyx fusicaudus) belongs to a monotypic genus within the family Talpidae. It is a small semi-fossorial mammal mostly distributed in south-western China. In this study, we obtained the complete mitochondrial genome of S. fusicaudus. The genome is a total of 16,602 bp in length, containing 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNA), 2 ribosomal RNA genes (rRNA) and 2 non-coding regions, with a base composition of 33.51% A, 28.73% T, 23.68% C and 14.08% G. The nucleotide sequence data of 13 protein-coding genes of S. fusicaudus and other 14 insectivora species were used to reconstruct a Bayesian phylogenetic tree. The tree shows that S. fusicaudus belongs to the subfamily Talpinae and is closely related to Urotrichus talpoides.
