Etymology

The generic name derives from the combination of the Latin acutus, meaning "sharp edge", and the Greek carpos, meaning "sac", in reference to the sharp edge of its left thecal margin. The specific epithet of A. delticus references the triangular outline of the theca, while the one of A. republicensis references Republic Creek, Wyoming, the collection place of its holotype.^[1]
