round-backed millipedes
Trigoniulidae is a family of round-backed millipedes in the order Spirobolida, comprising approximately 171 species across 25 genera. The family was established by Attems in 1909. Members are found in tropical and subtropical regions where they inhabit leaf litter and soil environments. Population studies of at least one species, Trigoniulus lumbricinus, indicate seasonal fluctuations correlated with rainfall patterns.
