Diplomaragnidae
Diplomaragnidae is a family of millipedes belonging to the order Chordeumatida. These millipedes range from 9 mm to 24 mm in length and are found from the Volga, Volga River region in Russia to Japan and Taiwan. All known adult females in this family have 32 segments (counting the collum as the first segment and the telson as the last) rather than the 30 segments typically found in this order; in most species, adult males also have 32 segments (e.g., ''Altajosoma kemerovo''), but in some species, adult males have only 30 segments (e.g., ''Diplomaragna reducta'').

Chordeumatida
Chordeumatida (from the Greek word for "sausage") is a large order of millipedes containing some 1200 species with a nearly worldwide distribution. Also known as "sausage millipedes," they possess around 30 body segments behind the head (including the telson) as adults and reach about in length. Description Chordeumatidans are relatively short-bodied, with only 26 to 32 body segments (including the telson) behind the head. They range in length from . A key feature is the presence of 6 large bristles (setae) on the dorsal surface of each body segment. The first segment ( collum) is relatively narrow, giving the appearance of a distinct "neck" in many species. The body tapers towards the rear, and the rearmost tip (telson) contains silk-producing organs (spinnerets). A dorsal groove runs down the length of the body, and some species possess paranota, lateral extensions of the exoskeleton. Paranota are also found in some other millipedes, notably Polydesmida, from which Chordeumat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
