Identification
Identification to level requires examination of and pattern characteristics. The four (L. heitzmanorum, L. permagnaria, L. sinuosa, L. unitaria) differ in wing pattern details and geographic distribution. L. permagnaria and L. unitaria were described in the 19th century, while L. heitzmanorum and L. sinuosa were described by Rindge in 1971, suggesting these latter species may be more recently distinguished cryptic or localized forms.
