Orthomorpha coarctata, the long-flange millipede,[1] is a widely introduced species of Polydesmidan millipede of the family Paradoxosomatidae. It is presumed native to Southeast Asia but due to transport by humans occurs in tropical and sub-tropical areas throughout the world, including the Hawaiian Islands, the West Indies, Gulf Coast of North America, and the Galápagos Islands.[1][2][3]
Description
[edit]Males range from 14.5–20.5 mm in length and 1.5 to 2.7 mm wide while females are somewhat larger ranging from 16.5–27.5 mm long, and 1.6–3.2 mm wide.[4] O. coarctata can be distinguished from Oxidus gracilis, another widely introduced Asian millipede, by having proportionally longer and pointier paranota (lateral keels) on mid-body segments and longer gonopods (male reproductive appendages).[5]
O. coarctata is unique within the genus Orthomorpha in that the gonopods have a single, simple tip, while other species have two or three lobes. This distinction has led some authors to place O. coarctata in a separate, monotypic genus, Asiomorpha.[2][4]
