What taxonomic practices based on the typological species concept are retained in systematics today?

Modern systematics has largely moved away from the typological species concept, which classifies species based on fixed traits of type specimens. However, some practices from this concept persist, such as the use of type specimens as reference points for species identification and description. Additionally, the concept of type locality remains important for understanding species distribution and ecology. While contemporary systematics emphasizes evolutionary relationships and genetic data, the historical influence of typological practices can still be seen in how species are formally described and categorized.
