Discussion : No other known species of Lita has the strongly marked, 

 angular line on the forewing. L. invariabilis has, as the name implies, 

 a stable color pattern. Observed variation occurs on the forewings 

 with the dorsal half basally and the apical third ranging from pale to 

 dark red brown.
