Definition

Noun: - A taxonomic class within the subphylum Myriapoda, comprising arthropods characterized by an elongated body composed of many similar segments, each typically bearing two pairs of legs. This class includes millipedes.

Usage Notes

• "Class Myriapoda" is a scientific term used in zoological taxonomy and biology. It is not used in everyday conversation. When used, it specifically refers to the taxonomic grouping.
• It is often used interchangeably with "Diplopoda" in broader or less technical contexts, though "Diplopoda" is technically the class for millipedes, a major group within Myriapoda.

Examples

• Scientific Context:
  • Millipedes belong to the class Myriapoda.
  • The fossil record provides evidence for early members of class Myriapoda.

Advanced Usage

• In detailed taxonomic discussions, "Myriapoda" is sometimes treated as a subphylum containing several classes, including Diplopoda (millipedes), Chilopoda (centipedes), Pauropoda, and Symphyla. However, the term "class Myriapoda" as defined here is a specific taxonomic rank.

Variants and Related Words

• Myriapod (n): A common name for any member of the subphylum or class Myriapoda.
  • A millipede is a type of myriapod.
• Diplopoda (n): The class containing millipedes.
• Chilopoda (n): The class containing centipedes.

Synonyms

• Diplopoda (when referring specifically to millipedes, the primary members of this class in this definition)

Notes on Meaning

• The provided reference definition equates "class Myriapoda" with arthropods having double somites and two leg pairs per segment, which is the defining characteristic of millipedes (class Diplopoda). In modern taxonomy, "Myriapoda" is more commonly a subphylum. Therefore, the term "class Myriapoda" is a specific, traditional classification for these many-legged arthropods, primarily millipedes.

Noun

1. arthropods having the body composed of numerous double somites each with two pairs of legs: millipedes
