Brachypauropodidae
''Brachypauropodidae'' is a family of pauropods. Like most adult pauropods in the order Tetramerocerata Tetramerocerata is an order of pauropods containing 12 different families and about 480 different species. Tetrameroceratans have a 12 segmented body, 4 segmented antennae, 6 tergites, and 8 to10 legs pairs of legs as adults. Most pauropods in ..., most adults in this family have 9 pairs of legs, but adults in a few species in two genera, ''Aletopauropus'' and ''Zygopauropus'', have only 8 pairs of legs.

Pauropods
Pauropods are small, pale, millipede-like arthropods. Around 830 species in twelve families are found worldwide, living in soil and leaf mold. They look rather like centipedes, or millipedes, and may be a sister group of the latter. However, this is controversial, as a close relationship with Symphyla has also been posited. Anatomy and ecology Pauropods are soft, cylindrical animals with bodies long. They have neither eyes nor hearts, although they do have sensory organs which can detect light. The body segments have ventral tracheal/spiracular pouches forming apodemes similar to those in millipedes and Symphyla, although the trachea usually connected to these structures are absent in most species. There are long sensory hairs located throughout the body segments. Pauropods can usually be identified because of their distinctive anal plate, which is unique to pauropods. Different species of pauropods can be identified based on the size and shape of their anal plate. The antenn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetramerocerata
Tetramerocerata is an order of pauropods containing 12 different families and about 480 different species. Tetrameroceratans have a 12 segmented body, 4 segmented antennae, 6 tergites, and 8 to10 legs pairs of legs as adults. Most pauropods in this order have 9 leg pairs as adults, but four genera (''Cauvetauropus'', ''Aletopauropus'', ''Zygopauropus'', and ''Amphipauropus'') have only 8 pairs, and adult females in the genus ''Decapauropus'' (in the Pauropodidae Pauropodidae is a family of pauropods. It contains over 20 genera and 650 species, as well as the only known fossil pauropod, '' Eopauropus''. Like most adult pauropods in the order Tetramerocerata Tetramerocerata is an order Order, ORDER or ... family) have either nine or ten pairs of legs. Pauropods in this order are generally 0.5 mm to 2 mm long, and are usually white or brown. Tetramerocerata has a subcosmopolitan distribution, occurring nearly worldwide.

Myriapod Families
Myriapods () are the members of subphylum Myriapoda, containing arthropods such as millipedes and centipedes. The group contains about 13,000 species, all of them terrestrial. The fossil record of myriapods reaches back into the late Silurian, although molecular evidence suggests a diversification in the Cambrian Period, and Cambrian fossils exist which resemble myriapods. The oldest unequivocal myriapod fossil is of the millipede ''Pneumodesmus newmani'', from the late Silurian (428 million years ago). ''P. newmani'' is also important as the earliest known terrestrial animal. The phylogenetic classification of myriapods is still debated. The scientific study of myriapods is myriapodology, and those who study myriapods are myriapodologists. Anatomy Myriapods have a single pair of antennae and, in most cases, simple eyes. Exceptions are the two classes symphylans and pauropods, and the millipede order Polydesmida and the centipede order Geophilomorpha, which are all eyeless ...
