Paraphrasing by Ann Hendrickson:
The recent publication by Matson and Wagner referenced below states that L. subfervens is the most common and wide-ranging species in the United States. My understanding is that if the forewings are sprinkled with red scales, they are L. subfervens.
They also discuss how difficult the Genus has been for many years and that many images of the Genus have been misidentified for years.
Both L. basistriga and the newly identified L. rubritegula have very limited ranges and have pearly white wings with distinct red markings.
L. basistriga is confined to deep South Texas and the newly identified L. rubritegula is found principally in limestone areas in the vicinity San Antonio, Texas, westward through
the southern Hill Country - however they consider the range to still be in flux as the species my have been heretofore neglected.
