Diagnosis. Smaller worm, 5-9 mm long with 24-34 segments. Chetae straight with ental hook, formula of 2,3- 2,3: 3-3. Hyalin and granular cells more or less in dense transversal rows ( Fig. 1A View Fig ), Clitellum saddle-shaped ( Fig. 1B View Fig ). Four pairs of preclitellar nephridia from 6/7. Oesophageal appendage ( Fig. 1C View Fig ) with a pair of unbranched tubes and with much coiled canal, the common opening dorsally into oesophagus behind pharyngeal pad. Coelomocytes mostly without refractile granule ( Fig. 1D View Fig ). Sperm funnels ( Fig. 1 View Fig E-G) and male copulatory organs ( Fig. 1H View Fig ) small. Ectal ducts of spermathecae shorter than ampullae, glands on distal part of ectal ducts ( Fig. 1I View Fig ). Ental ducts mostly long, open separately into oesophagus.

Remarks. The genus Enchytraeus Vejdovský, 1879 is currently composed of 49 valid species ( Schmelz and Collado, 2012). E. buchholzi is one of the largest dominant species in the soil with a cosmopolitan distribution. This species and other smaller Enchytraeus species are cultured by aquarists as fish food. They are ideal for most rainbow fishes (adults and larger fries).

Habitat and distribution. Terrestrial, except strongly acidic soils. Widespread, cosmopolitan ( Schmelz and Collado, 2010).
