Polydesmidae
Polydesmidae is a family of millipedes in the order Polydesmida. These millipedes range from 4 mm to 30 mm in length. This family includes species notable for featuring sexual dimorphism in segment number: Adult females in the genus ''Perapolydesmus'' have the usual 20 segments (counting the collum as the first segment and the telson as the last), but the adult males have only 19.

Brachydesmus
''Brachydesmus'' is a genus of millipedes belonging to the family Polydesmidae Polydesmidae is a family of millipedes in the order Polydesmida. These millipedes range from 4 mm to 30 mm in length. This family includes species notable for featuring sexual dimorphism in segment number: Adult females in the genus ''Perapolydes .... Millipedes in this genus are found mainly in Europe. Species in this genus have only 19 segments as adults (counting the collum, the telson, and the rings in between), one fewer than found in most polydesmid species. Accordingly, adults in this genus have two fewer legs than most polydesmid adults have: Females have only 29 pairs of legs, and males have only 28 pairs of walking legs, excluding one pair of gonopods. Species in this genus arrive at these lower numbers of legs and segments by going through the same stages of teloanamorphosis observed in other polydesmids but reaching maturity one moult earlier. Species Species within this genus include: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polydesmida
Polydesmida (from the Greek ''poly'' "many" and ''desmos'' "bond") is the largest order of millipedes, containing approximately 3,500 species, including all the millipedes reported to produce hydrogen cyanide (HCN). Description Members of the order Polydesmida are also known as "flat-backed millipedes", because on most species, each body segment has wide lateral keels known as paranota. These keels are produced by the posterior half (metazonite) of each body ring behind the collum. Polydesmids have no eyes, and vary in length from . Many of the larger species show bright coloration patterns which warn predators of their toxic secretions. Adults usually have 20 segments, counting the collum as the first ring and the telson as the last ring. Juveniles have from 7 to 19 rings. In species with the usual 20 segments, adult females have 31 pairs of legs, but in adult males, the eighth leg pair (the first leg pair of the 7th ring) is modified into a single pair of gonopods, leaving o ...
