El cladismo o escuela taxonomica dadista, destaca el valor fundamental de la cladogenesis (historia de los sucesos de especiacion por ramificacion) y da un lugar secundario a otros elementos componentes de la filogenia mas relacionados con la anagenesis: polaridad evolutiva (direccion de cambio o serie de transformacion), relaciones patristicas o divergencia evolutiva (cantidad relativa de cambio), cronologia de la historia evolutiva de los organismos basada en registro fosil y diversificacion en nuevos ambientes siguiendo una radiacion evolutiva (Llorente-Bousquets y Vega 1994; Quicke 1993).

For groups of butterflies such as the Satyridae, the study of the lengths of the palpi segments is quite variable and it does not allow the subtraction of characters of important taxonomic value at any hierarchical level, mainly to establish homologies, since said structures could have been originated in multiple and independent ways in the cladogenesis of the Rhopalocera (VILORIA, Op.
