Cryptic biodiversity, the presence of suborganismal variation in isomorphic populations of organisms, can have implications for management and conservation. Ecological variation in habitat and host species of populations of the black fly Simulium johannseni suggested the potential for cryptic biodiversity. Polytene chromosomes of larvae belonging to the S. johannseni group of black flies were characterized to discover fixed and polymorphic rearrangements. Larvae of S. johannseni from Wisconsin, South Carolina, and Alabama and of the closely related S. parmatum from South Carolina and Florida were analyzed. Simulium johannseni can be divided into two cytoforms corresponding to geographic location. Cytoform A, found …
