Lumbricidae
The Lumbricidae are a family of earthworms. About 33 lumbricid species have become naturalized around the world, but the bulk of the species are in the Holarctic region, from Canada (e.g. ''Bimastos lawrenceae'' on Vancouver Island) and the United States (e.g. ''Eisenoides carolinensis'', '' E. lonnbergi'', and most '' Bimastos'' spp.) and throughout Eurasia to Japan (e.g. ''Eisenia japonica'', ''E. koreana'', and ''Helodrilus hachiojii''). An enigmatic species in Tasmania is '' Eophila eti''. Currently, 670 valid species and subspecies in about 42 genera are recognized. This family includes the majority of earthworm species well known in Europe and Asia. Genera The family consists of these genera: * '' Allolobophora'' Eisen, 1874 * '' Alpodinaridella'' Mršić, 1987 * '' Aporrectodea'' Orley, 1885 * '' Bimastos'' Moore, 1893 * '' Castellodrilus'' Qiu & Bouché, 1998 stat. nov. * '' Cataladrilus'' Qiu & Bouché, 1998 * '' Cernosvitovia'' Omodeo, 1956 * '' Creinella'' Mršić, ...

Earthworm
An earthworm is a soil-dwelling terrestrial invertebrate that belongs to the phylum Annelida. The term is the common name for the largest members of the class (or subclass, depending on the author) Oligochaeta. In classical systems, they were in the order of Opisthopora since the male pores opened posterior to the female pores, although the internal male segments are anterior to the female. Theoretical cladistic studies have placed them in the suborder Lumbricina of the order Haplotaxida, but this may change. Other slang names for earthworms include "dew-worm", "rainworm", "nightcrawler", and "angleworm" (from its use as angling hookbaits). Larger terrestrial earthworms are also called megadriles (which translates to "big worms") as opposed to the microdriles ("small worms") in the semiaquatic families Tubificidae, Lumbricidae and Enchytraeidae. The megadriles are characterized by a distinct clitellum (more extensive than that of microdriles) and a vascular system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aporrectodea
''Aporrectodea'' is a genus of earthworms in the family Lumbricidae. The genus includes some of the most common earthworms in the Palearctic realm and in agricultural soils across the temperate regions of the world.Pérez-Losada, M., et al. (2009)Phylogenetic assessment of the earthworm ''Aporrectodea caliginosa'' species complex (Oligochaeta: Lumbricidae) based on mitochondrial and nuclear DNA sequences.''Molecular Phylogenetics and Evolution'' 52 293–302. Several species are found throughout the world today, having been widely introduced via agriculture. One of these widespread species, ''A. trapezoides'', was also transported across continents as a popular fishing bait.Fernández, R., et al. (2010)Life cycle and reproductive traits of the earthworm ''Aporrectodea trapezoides'' (Dugès, 1828) in laboratory cultures.''Pedobiologia'' 53 295–99. Some species of this genus are known to be important in the process of soil formation. Among the most familiar species is ''Aporrec ...
