L. licina
L. venusta
Identification
Comparison of L. argyra (left) and L. venusta (right):

The markings of L. venusta and L. argyrobapta are generally similar in shape. Where their ranges overlap (coastal southeast US except for most of Florida, where L. venusta is not found), a distinction can typically be made by looking at the markings on the dorsal posterior abdomen:
L. argyrobapta has bright orange/red markings.
L. venusta has silver or yellow markings.
This distinction is generally not visible in alcohol-preserved specimens.

If performing identification via genitalia, a mature male palp is needed to distinguish L. venusta from L. argyrobapta, as there are no reliable differences in female epigyna.(1)
Range
L. argyra - Florida to Brazil
L. argyrobapta - Coastal southeastern US to Brazil
L. licina - West Indies, now in south Florida
L. venusta - USA, Canada
