Complete mitochondrial genome of Neochalcosia remota (Walker, 1854) (Lepidoptera: Zygaenidae)

The Zygaenidae family comprises diurnal moths recognized for their bright coloration and chemical defenses. Despite its ecological and evolutionary significance, mitochondrial genome (mitogenome) data remain scarce. Here, we present the mitogenome of Neochalcosia remota, the first to be elucidated in members of the Neochalcosia genus, in the Chalcosiinae subfamily. The complete mitogenome is 15,246 bp and contains the standard set of 37 genes, with 13 protein-coding genes (PCGs), 22 tRNAs, and 2 rRNAs, as well as an A + T-rich region. An inverted translocation of the trnE-trnS1 block (underlined gene names indicate a counter-clockwise transcriptional direction), instead of the typical trnS1-trnE arrangement in Lepidoptera, present in all Zygaenidae species, was also detected in N. remota. Phylogenetic analyses based on the 13 PCGs and two rRNAs in the Zygaenidae strongly supported the monophylies of this family and its subfamilies (Chalcosiinae, Procridinae, and Zygaeninae), placing N. remota as a sister taxon to Eterusia aedea. As a new contribution to the mitogenome database, the mitogenome of N. remota could provide valuable genetic data leading to a diverse taxonomic hierarchy in phylogenetic studies.
