A neotype was not established until 2010 when one based on specimens collected in the type locality was established. At that time, L. venusta was declared a senior synonym of L. argyrobapta, but in 2018, argyrobapta was removed from that synonymy, and is now recognized as a separate species. These two species are grossly differentiated by geographic range (venusta is more northern and found in temperate climes, while argyrobapta is typically more tropical and coastal).

Although there may be some generalized marking difference, more precise determination requires microscopic examination of the genitalia. "Surprisingly,", according to Ballesterosa and Hormiga, 2018,these are not sister species, as their "estimated age of divergence implies that the morphologies in this two species...have remained seemingly invariable for at least 10 million years.
