Consideraciones sobre la identidad de Onychochaeta elegans (Cognetti, 1905) (Oligochaeta, Glossoscolecidae)

Abstract

Considerations on the identity of Onychochaeta elegans (Cognetti, 1905) (Oligochaeta, Glossoscolecidae)

Anatomical variability of Onychochaeta elegans in Cuban populations was studied. A comparison among these populations and O. elegans cubana Michaelsen, 1924 and O. cubana Zicsi, 1995 from Cuba, as well as the descriptions of the typical form of Cognetti (1905) from Panama and Colombian specimens (Righi, 1995) was made. Besides, new materials from Mexico and Panama were added. Variations in anatomical characters in Cuban populations included those present in continental forms, so, there were not any character that justifies the division of O. elegans nor subspecies neither in distinct insular and continental species.
