Similar to M. curtus, M. biporus comprises a complex of many species of quite distinct morphology, but their relationships, distribution and diagnostic characters are poorly understood. The name-giving character of the type specimens of M. biporus is a the presence of double rudiments of femoral glands in females, and of the populations studied by us, such glands have only be observed in specimens from Fierenana and near Moramanga which we therefore consider to represent the real species M. biporus.
