Trigoniulus is a of millipedes in the Trigoniulidae, established by Pocock in 1894. The genus contains at least 90 described distributed primarily across tropical and subtropical regions of Asia. Species such as Trigoniulus corallinus and T. lumbricinus have been studied for their , revealing seasonal abundance patterns correlated with rainfall and temperature. The genus serves as a for gut-associated microbes, including bacteria isolated from decaying plant .

Habitat

occur in open land rich in organic matter and in decaying coconut trees. correlates with minimum temperature and rainfall.

Distribution

Asia; specific distribution varies by . Trigoniulus corallinus described as the "common Asian millipede."

Seasonality

and late stadia abundant in June, October, and November; August include all developmental stages. population peaks occur May–July for some .

Host Associations

  • Pseudomonas schmalbachii - gut Bacterial isolated from digestive tract of Trigoniulus corallinus

Life Cycle

Developmental stages show length progression factor 1.11–1.98 (mean 1.43) and width progression factor 1.10–1.56 (mean 1.31). Females exhibit higher weight progression factor than males, attributed to accumulation of -forming tissue.

Behavior

Aggregated distribution pattern during peak abundance periods, driven by patchy food distribution, soil moisture, and sexual attraction.
