Summary

Platydesmida is an order of millipedes that includes around 60 species in two families. They are characterized by their flattened bodies, lack of eyes, and unique reproductive behavior among some species, such as paternal care.

Physical Characteristics

Body flat with tiny heads and 30‒192 body rings. Eyes absent. Paranota always present. Body usually pink with a rough dorsum and a narrow groove. Up to 60 mm in length.

Identification Tips

Look for flattened body shape and lateral extensions (paranota) on each segment. Absence of eyes is a key identification feature.

Habitat

Typically found in decomposing leaf litter and associated environments; some may specialize in fungal habitats.

Distribution

North America, Central America, Mediterranean region of Europe, Japan, China, southeast Asia, and Indonesia.

Diet

Primarily feed on dead or decomposing leaf litter; some species may specialize in feeding on fungi.

Reproduction

Some species exhibit paternal care, with males coiling around eggs and young.

Ecosystem Role

Evolution

The only described fossil of the order is from the Mid Cretaceous (~100 Ma) Burmese amber, belonging to the genus Andrognathus.
