Class Diplopoda

Millipedes have a long body and many legs. Millipedes have two pairs of legs per (diplo)segment, while centipedes have one pair per segment.

There are 33 species in Singapore[1].

The most commonly recognisable type is this red millipede - Trigoniulus corallinus. It has a cylindrical body and curls into a coil when threatened.

The other type that one might encounter are the plated millipedes (Order Polydesmida). Anoplodesmus saussurii, often confused with Harpaphe haydeniana[2], is very common in newly developed lands. But it is an introduced species. Another introduced species is Chondromorpha xanthotricha[3], which looks like Anoplodesmus saussurii, but is not glossy and has less yellow.

The other plated millipedes can be found in the forests. One such species is Opisthodolichopus scandens[4].
