The genus Acanthaspis (Hemiptera: Reduviidae) comprises predatory insects of ecological importance, yet mitochondrial genomic resources for this group remain limited. Here, we present the complete mitochondrial genome of Acanthaspis geniculata (Hsiao, 1976). The mitogenome is 16,226 bp in length and contains the standard set of 37 mitochondrial genes (13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes), along with a control region (D-loop). The nucleotide composition is A (40.4%), T (29.6%), C (17.9%), and G (12.1%), with an overall AT content of 70.0%. Phylogenetic analyses based on partitioned mitochondrial datasets strongly support the monophyly of the subfamily Reduviinae and reveal that A. geniculata forms a close sister-group relationship with A. ruficeps and A. pedestris. This study provides a fundamental mitogenomic resource for future evolutionary and systematic studies of the Reduviidae.
