Semispecies relationships between Heliconius erato cyrbia Godt. and H. himera Hew. in southwestern Ecuador

Abstract

"As Bernardi (1980) stressed, the study of "semispecies" (quasi and vice species, according to the terms he and ourselves consider correct) is of strategic importance to clear up the mechanisms of speciation. However, in the present case, and though Heliconius are becoming the best genetically known butterflies, one may cast doubts about the observations and experimental facilities offered by populations flying in remote parts of southern Ecuador, while it is already difficult to reach conclusive evidences in more accessible countries."
