Eutrichodesmus Monodentus
''Eutrichodesmus'' is a genus of millipedes in the family Haplodesmidae. Containing 54 species, this genus is among the genera with the greatest number of species not only in the family Haplodesmidae but also in the order Polydesmida. This genus includes the species '' E. peculiaris'', notable for featuring sexual dimorphism in segment number: The adult females have 20 segments (counting the collum as the first segment and the telson as the last), but the adult males have only 19 segments. Millipedes in this genus are found in southern Japan, Taiwan, southern China, mainland Southeast Asia, Indonesia, and Vanuatu. Description Millipedes in this genus are small, ranging from 3.5 mm to 14 mm in length. These millipedes can have 19 or 20 segments. Species in this genus are capable of volvation, which is usually complete but sometimes incomplete. The basal element of the gonopod (coxa) in adult males in this genus usually features abundant setae. The distal element of t ...

Doratodesmus
''Doratodesmus'' is a is a genus of flat-backed millipedes in the family Haplodesmidae. These millipedes are found in China, Indonesia, and Papua New Guinea. This genus includes two species that are notable for including adult males with only 18 segments (counting the collum as the first and the telson as the last) rather than the 20 segments normally observed in the order Polydesmida: '' D. hispidus'' features only 18 segments in adults of each sex, whereas '' D. pholeter'' exhibits sexual dimorphism in segment number, with 19 segments in adult females but only 18 segments in adult males. Discovery, taxonomy, and distribution The American biologist Orator F. Cook proposed the name ''Doratodesmus'' in 1895 for two species previously described under the name ''Doratonotus'', which was already occupied. In 1894, the British zoologist Reginald I. Pocock described the type species ''Doratonotus armatus'' as a new species discovered on the island of Java in Indonesia. In 1895, t ...

Seta
In biology, setae (; seta ; ) are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Depending partly on their form and function, protostome setae may be called macrotrichia, chaetae, Scale (insect anatomy), scales, or Common name, informally, hairs. The setal membrane is not Cuticle, cuticularized, so movement is possible. Annelid setae are stiff bristles present on the body. They allow earthworms and their relatives to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (the group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. The setae on polychaete worms are referred to as chaeta due to their differing morphology. Crustaceans have mechano- and chemos ...
