Fairy shrimps (Anostraca) constitute an important component of seasonally aquatic habitats, but few complete mitochondrial genomes have been published for this group. Here, we report the mitogenome of a common southern African species, Streptocephalus cafer, from Botswana (accession number: MN720104). Low-coverage shotgun sequencing recovered two contigs 15653 bp and 1347 bp in length that are separated by a repetitive region of unknown length within the non-coding control region. The mitogenome's GC content is 31.80%. Phylogenetic analysis using protein-coding genes confirms the sister taxon relationship of S. cafer with the only other congener whose mitogenome has been reconstructed to date, the Asian S. sirindhornae.

“…MitoZ annotation reported several instances of non-canonical start codons and truncated stop codons, consistent with other studies on arthropods (Monsanto et al. 2019 ).…”

“…The GC content of the assembly was estimated at 33.52%. Several instances of non-canonical start codon and incomplete stop codons were observed, as for other arthropods (Monsanto et al 2019;Jagatap et al 2019). Protein coding sequences from the studied species, eight closely related species with complete mitogenomes in the NCBI database, and an outgroup (Dysdercus evanescens) were aligned in MAFFT v7.429 (Katoh et al 2009).…”

Clam shrimps (Spinicaudata) are a widespread and diverse crustacean group that frequent temporary aquatic habitats, but few complete mitochondrial genomes have been published for this group. Here, we report the mitogenome of an undescribed Gondwanalimnadia species from Botswana. Raw sequences were assembled into a single circular genome with a total length of 15,663 bp. Thirteen proteincoding genes, 22 tRNAs, and 2 rRNAs were identified using the MITOS pipeline. The mitogenome's GC content is 33.52%. Phylogenetic analysis using protein-coding genes confirmed that Gondwanalimnadia sp. is closely related to another member of the Limnadiidae, Limnadia lenticularis.

“…Annotation of the reconstructed mitogenome in MITOS webserver (Bernt et al 2013) identified 13 protein-coding genes, 22 tRNAs, and 2 rRNAs, as is typical of all crustaceans. Instances of noncanonical start codons and truncated stop codons were observed (Jagatap et al 2019;Monsanto et al 2019). The protein-coding DNA sequences of the study species were aligned with those of eight closely related crustaceans in MAFFT v7.429 (Katoh and Standley 2013).…”

Spinicaudatan clam shrimp are a widespread and diverse group of branchiopod crustaceans, yet few mitochondrial genomes have been published for this taxonomic group. Here, we present the mitogenome of Leptestheria brevirostris from a rock pool ecosystem in Botswana. Massively parallel sequencing of a single specimen facilitated the reconstruction of the species' 15,579 bp circularized mitogenome. The reconstructed phylogenetic tree confirms that L. brevirostris forms a monophyletic group with other diplostracan branchiopods, and that these are the sister taxon to Notostraca. The mitogenome reconstructed here is the first to be reported from a leptestherid clam shrimp.
