Description

• Rhysodesmus is a genus of millipedes in the family Xystodesmidae. Members typically have broad, flattened bodies with numerous segments, each bearing two pairs of legs on most trunk segments. Their bodies may be dark brown, black, or reddish, sometimes with contrasting pale markings or coloured edges along the segments. Like other millipedes, they move slowly and may coil or release defensive chemicals when threatened.

Range

• Rhysodesmus is present in Zihuatanejo, Guerrero, Mexico. The genus is primarily associated with Mexico and parts of Central America, where different species occupy distinct geographic ranges.

Habitat

• Members of Rhysodesmus are generally associated with terrestrial habitats that provide shelter and moisture, including forest leaf litter, decaying logs, soil beneath stones, and areas with decomposing vegetation. They are often found in humid microhabitats where organic matter accumulates.

Diet

• Members of Rhysodesmus are primarily detritivores, feeding on decomposing leaves, rotting wood, and other dead plant material. They may also consume fungi and associated microorganisms. Their feeding contributes to the breakdown of organic matter and nutrient cycling in forest soils.
