Similar Taxa
- Abedus herbertiClosely related congeneric with similar and paternal care ; distinguished by subtle pronotal differences
- Belostoma speciesOther giant water bugs in Belostomatidae with similar body plan and aquatic predatory habits; Belostoma generally larger with different -carrying (some on vegetation rather than male backs)
