The mitogenome of the Northern Hemisphere native terrestrial flatworm <i>Rhynchodemus sylvaticus</i> (Leidy, 1851) (Platyhelminthes, Geoplanidae)

<i>Rhynchodemus sylvaticus</i> (Leidy, 1851) is a tiny terrestrial flatworm of the subfamily Rhynchodeminae (Platyhelminthes, Geoplanidae) generally found in Europe and North America. Its mitogenome is 16,891 bp long, contains 12 protein-coding genes, two rRNA genes and 21 tRNA genes. No <i>tRNA-Thr</i> was found, <i>ND6</i> starts with ATT, <i>cob</i> is longer at its 3’ ending. Unlike the other eight species of Rhynchodeminae with sequenced mitogenomes, there is a real stop codon for <i>ND5.</i> Also, the position of tRNA-Met differs. Multiprotein phylogeny shows <i>R. sylvaticus</i> within a clade including species of the tribe Rhynchodemini from Oceania, but distinguished by a long branch.
