| Sumario: | [EN] Making use of the distance to the source, an anylisis of the longitudinal distribution of 32 taxa of Hydraenidae and Elmidae frorn lotic environments is carried out. By means of a statistical method, the indicator species in relation to this factor have been identified. Three groups of taxa have been distinguished according to their distribution: species of upper reaches, those of lower reaches and those widely distributed. Both families are compared in terms of their longitudinal zonation; Hydraenidae have been found to be more closely related to upper reaches, whereas Elmidae show, as a whole, a wider ecological amplitude and a preference to areas near the confluence |
