Chamaesomatidae Explained

Chamaesomatidae is a family of millipedes belonging to the order Chordeumatida.^[1] This family contains 28 species distributed among 11 genera. These millipedes are found in Europe and North Africa.^[2]

Description

These millipedes range from 3.3 mm to 12 mm in length. The paranota are small and humplike. Many species lack pigment and dwell in caves. Adult millipedes in this family have 26, 28, or 30 segments (counting the collum as the first segment and the telson as the last). This family includes the species Chamaesoma broelemanni, notable as one of only a few chordeumatidan species with only 26 segments in adults, four fewer segments than typically found in adults in this order.^{[3] [4]}
