Foram feitas provas de cruzamento entre espécimes de uma população de A. glabratus e de outra de A. nigricans, utilizando o fator de albinismo como mercador genético. O resultado dessas provas revelou completo isolamento reprodutivo entre ambas, permitindo separá-las como boas espécies de acôrdo com o critério biológico. Crossing experiments were made between specimens from one population of A. glabratus and another of A. nigricans, the factor of albinism having been used as genetic marker. The results of those experiments revealed a complete reproductive isolation between both population, thus indicating their specific distinctness according to the biological criterion.
