Abstract

One complete mitochondrial genomes (mitogenomes) was determined for Heterochaerus australis (Acoela, Convolutidae). Its mitochondrial genome size was 13,885 bp. The sequence contains 2 ribosomal RNA genes (rrnL and rrnS), 20 tRNA genes, and 12 protein-coding genes (PCGs). The A + T content of the complete mitochondrial genome sequence was 70.8%. The base composition showed a tendency of high AT. The resulted maximum likelihood (ML) tree supported that Acoela had a distant relationship with other orders of Turbellaria and the Xenacoelomorpha.

Keywords: Acoela; Heterochaerus australis; Xenacoelomorpha; mitogenome.
