lipotyphla

A hedgehog, a mole, and a shrew are all members of the order Lipotyphla.

Definition

Noun 1. An obsolete taxonomic order of mammals: "Lipotyphla" was a scientific classification for a group of small, insect-eating mammals, primarily characterized by a simple, smooth brain structure and the absence of a cecum. This order historically included families such as moles, hedgehogs, and true shrews. It is now considered an invalid grouping in modern taxonomy.

Usage Notes
  • The term "Lipotyphla" is used almost exclusively in scientific and historical biological contexts.
  • It is a taxonomic term, meaning it is used for the classification of living organisms.
  • This word is now considered obsolete. In modern biological classification, the animals once grouped under Lipotyphla are now distributed within the larger order Eulipotyphla.
Examples of Usage
  • Noun:
    • The order Lipotyphla was distinguished by its members' primitive skull and dental features.
    • Early 20th-century zoology texts often classified shrews within the Lipotyphla.
Advanced Usage
  • Historical Context: The term is useful when reading older scientific literature. A modern reader might encounter "Lipotyphla" and need to understand it refers to what is now called Eulipotyphla.
    • The fossil record suggests members of the former Lipotyphla were widespread in the Eocene epoch.
Variants and Related Words
  • Eulipotyphla (n): The modern, valid taxonomic order that includes the families formerly placed in Lipotyphla (e.g., shrews, moles, hedgehogs, solenodons).
    • The order Eulipotyphla contains some of the world's smallest mammals.
Synonyms
  • Insectivora (in part): An older, broader, and also obsolete order that included lipotyphlan families along with others like tenrecs and golden moles.
  • Eulipotyphla: The modern, accepted synonym for the core group of animals.
Key Distinction
  • Lipotyphla vs. Eulipotyphla: "Lipotyphla" is the obsolete term. "Eulipotyphla" is the current, accepted scientific order. They refer to largely the same group of animals, but "Eulipotyphla" reflects updated phylogenetic understanding.
