Six species are documented from the Nearctic Region, including the type species and one newly described species (A. falcata). Species-level taxonomy has been revised with morphological descriptions, genitalia illustrations, and distribution mapping.

The genus contains two described species, L. acuta and L. tergisa, both restricted to the Nearctic Region.
