Lumbricus is a genus of earthworms that includes around 700 species . It is characterized by afirst body segment ( peristomium )completely dividedby the prostomium and grooves that form the edge of the prostomium and run up to the groove between the first two segments ( tanylobic head anatomy). The testes and vas deferens are surrounded by a small pouch and are present in segments nine, eleven, and twelve. The bristles are closely paired. The nephridial bladders are J-shaped.
Common species from Central Europe are:
- Lumbricus rubellus (red forest earthworm) , a usually red-brown or red-purple worm 7 to 15 cm in length
- Lumbricus castaneus (brown leaf eater) is chestnut brown to purple brown and about 3 to 5 cm long
- Lumbricus terrestris (dewworm) or common earthworm, a 9 to 30 cm long worm with a dark body at the top and dark vertical stripes at the back
- Lumbricus festivus is red-brown and 5 to 10 cm long
- Lumbricus badensis (Baden giant earthworm) is similar to L. terrestris and reaches a length of 34 to 60 cm
