Forty‐four cnchytraeid species and one parergodrilid species are reportcd from terrestrial habitats in Sweden. Eighteen of the Enchytraeidae are ncw records, including Achueta bifollicula sp.n. Thc new species has 4046 segments; dorsal sctal follicles; follicle‐like bodics vcntrally at IV and V; clitellum dorsally interrupted, with fields of hyaline cells; three pairs of primary septa1 glands, and one pair of secondary ones behind 5/6; dorsal blood vessel originating in VII; anteclitellar nephridia in three pairs at 6/7‐8/9; long, large spermathecae reaching to X‐XII; sperm funnels with a 1ength:width ratio G7:l; seminal vesicles extending through three scgments. The usefulness of the clitellar structure of A chaeta species as a taxonomic critcrion is discussed.
