Since its establishment, its position has been controversial but never rigorously tested. To address this perplexing issue, we are the first to present the complete mitochondrial sequence of <i>Oculogryphus</i>, using the material of <i>O. chenghoiyanae</i> Yiu & Jeng, 2018 determined through a comprehensive morphological identification. Our analyses demonstrate that its mitogenome exhibits similar characteristics to that of <i>Stenocladius</i>, including a rearranged gene order between <i>trnC</i> and <i>trnW</i>, and a long intergenic spacer (702 bp) between the two rearranged genes, within which six remnants (29 bp) of <i>trnW</i> were identified. Further, we incorporated this sequencInsectsA Mysterious Asian Firefly Genus, <i>Oculogryphus</i> Jeng, Engel & Yang (Coleoptera, Lampyridae): The First Complete Mitochondrial Genome and Its Phylogenetic Implications.PMC11277304DXK20210332270491C202220100532270491, 3177250731772507Yang YXLiu HYGe XYYuan SLLi XYKang YfalseA Mysterious Asian Firefly Genus, <i>Oculogryphus</i> Jeng, Engel & Yang (Coleoptera, Lampyridae): The First Complete Mitochondrial Genome and Its Phylogenetic Implications.The firefly genus <i>Oculogryphus</i> Jeng, Engel & Yang, 2007 is a rare-species group endemic to Asia.
