Trigoniulus corallinus
Rusty Millipede, Common Asian Millipede
Trigoniulus corallinus is a large millipede native to the Indo-Malayan region that has become established as an introduced species across multiple continents. Adults reach 50–75 mm in length and are characterized by a uniform reddish-brown coloration. The species inhabits moist terrestrial environments, particularly areas rich in decaying organic matter. It was the first millipede to have its genome sequenced (2015), and subsequent research has identified an XX/X0 sex chromosome system with males possessing modified seventh-leg pairs (gonopods) used for mating.
