Description
Stemmiulids are small to medium sized millipedes, reaching a maximum length of 50 mm (2 in). The body tapers gradually, and is laterally compressed, so is taller than wide. A dorsal groove is present and runs from head to tail. The eyes consist of two large ocelli on each side of the head, and some members are capable of jumping.[1][2] The living species lack Tömösváry organs, although a fossil species from the Miocene epoch possesses them.[3]
Classification
Stemmiluda contains 6-10 living genera and at least one fossil genus, all in the family Stemmiulidae. Species estimates range from about 120 to 150 species.[4][5] The taxonomy is controversial, with some authors lumping species into as few as three genera.[5] The most liberal classification is presented below.[6]
