Abstract

Detailed descriptions and illustrations are provided of the ultimate instar larvae of Argia medullaris and Argia variegata from Colombia. The principal features are outlined and compared with other species. Argia medullaris differs from other species of the genus by the parallel width of the lateral gills and prominent ligula; the A. variegata larva can be separated from other species by the absence of setae and spines on male and female gonapophyses and its peculiar madicolous habit.
