El Genero Nacobbus Thorne & Allen, 1944 en Argentina. 3. Caracterizacion Morfologica y Morfometrica de Poblaciones de N. aberrans (Thorne, 1935) Thorne & Allen, 1944
A study was conducted in Argentina to characterize seven Nacobbus aberrans populations having different host preference and geographical origin. Statistical evaluation of morphological and morphometric parameters of these populations showed a wide range of variability within each population. No evidence of morphological differences was detected among the populations. However, morphometric parameters of these populations were different (P = 0.05) and distinct according to the geographical origin of each population.
