Gastrotricha (hairy-bellied worms) is a phylum of microscopic aquatic invertebrates whose traditional morphology-based classification has been challenged in recent years. We report a new genus and species found using an integrative morphological and molecular approach, which is unrelated to morphologically similar species in the genera Aspidiophorus and Heterolepidoderma. The mitochondrial genome of the new taxon has the same number of genes and gene order as the only other gastrotrich mitogenome available, suggesting the conservation of mitochondria at the family level.
