The complete mitochondrial genome of rare and Critically Endangered Anilany helenae (Microhylidae) of Madagascar

Anilany helenae is a Critically Endangered frog native to the central highlands of Madagascar. Due to ongoing habitat loss of its known range, this species’ population is considered declining, while little is known about its ecology, behavior, and taxonomy. Within the context of developing tools that can aid the conservation of Madagascar’s amphibian fauna, and add to the continued understanding of their taxonomy, we assembled its complete mitochondrial genome (Genbank Accession number MZ751042). This contributes the first complete mitochondrial genome of a microhylid from Madagascar, despite there being over 100 species in the Cophylinae subfamily alone. Anilany helenae’s circular mitochondrial genome is 17,519 bp long, contains 37 genes, and exhibits differences in gene arrangement compared with other microhylids, including the placement of protein coding genes nad1 and nad2. A phylogeny of the 13 protein coding genes of the few Madagascan anuran mitogenomes available, along with species from Africa and East Asia, places A. helenae along with the New Guinean Mantophryne lateralis in a basal position with respect to the other microhylids in the tree.
