The main goal of this study was to improve a phylogeny and classification for species referable to Sparganothina. Sparganothina was originally described on the basis of the following five characters: reduction to a trace or loss of the ocelli; reduction to a trace or loss of vein CuP in the forewing; the rudimentary and joined gnathos; the heavily sclerotized sacculus, enlarged distally with a free tip or projecting spur; and the nearly closed collarlike signum of the females. It is not possible however to use these characters to define Sparganothina as monophyletic when the array of new species is considered and if the four originally included species remain in the genus. The reduced gnathos serves more adequately than the other four characters to define the tribe as a whole. Additionally, undescribed species are recognized, but the unique male specimen is too badly damaged to be described or illustrated with accuracy.
