"T. ceperoi" males are able to distinguish between similar species, but not between sexes, due to a rather large sexual dimorphism. Sexual dimorphism is the different characteristics present in individuals of the same species, but opposite sexes. The sexual dimorphism between the two sexes is a result of a single additional instar in the female larval stages. This indicates the male emerges sooner than the female and therefore can link the larger size to the additional period of growth.
