Twelve families of earthworms occur in North America north of Mexico - Acanthodrilidae, Criodrilidae, Lutodrilidae, Glossoscolecidae, Komarekionidae, Lumbricidae, Eudrilidae, Megascolecidae, Octochaetidae, Ocnerodrilidae, Sparganophilidae, and Haplotaxidae (most often considered an aquatic microdrile family, with one genus and one nominal species in North America); we recognize 40 genera and 159 nominal species in these families. Of these, 47 nominal species representing 22 genera in 8 families occur in Illinois. Several of these primarily terrestrial oligochaetes - Eisenia foetida and Eiseniella tetraedra (Lumbricidae), and some of the enchytraeids (Enchytraeidae) - frequently are collected from freshwater systems; these and a few others are commonly collected from moist and muddy (limicolous) habitats as well. Haplotaxis cf. gordioides (Haplotaxidae), a species that has not yet been collected in its sexually mature state in North America, is most commonly associated with groundwater habitats (springs, cave streams, wells, cisterns).

In addition to terrestrial oligochaetes, one semi-terrestrial leech - Haemopis terrestris (Forbes, 1890) (Hirudinea, Haemopidae) - also occurs in Illinois.

Historical works focusing on one or more aspects of terrestrial oligochaetes in Illinois include those by Forbes (1890a,b), Garman (1888, 1890), the numerous studies of Smith (1895a,b, 1896, 1900a,b, 1912, 1917, 1922, 1924, 1925, 1928), and those of Smith and Gittens (1915), Smith and Welch (1913), Welch (1914), and Harman (1960).

The list below has been compiled from records that have been published in the historical or recent scientific literature. Of note here are the species from the Walter J. Harman Terrestrial Annelida Collection, graciously donated to the Illinois Natural History Survey (INHS) Annelida Collection in Champaign by Dr. Harman in the late 1980s. The list also accounts for recent nomenclatural and systematic changes. Many recent works discussing the phylogeny of aquatic Annelida also have been included in the section on classification below. References noted in the text of this document are included in the 'Literature Cited' section which follows the checklist of species.

Classification of Annelida. Several classifications for the phylum Annelida have been proposed over the last 20 years. The reader is directed to Jamieson (1978, 1980, 1988), Timm (1981), Brinkhurst (1982, 1986, 1988, 1989, 1991a, 1991b, 1991c, 1992, 1994), Kasprzak (1982, 1984), Kathman and Brinkhurst (1998), Parker (1982), Holt (1986, 1989), Erséus (1987, 1990), Sawyer (1986a, 1986b, 1986c), Brinkhurst and Nemec (1987), Coates (1987, 1989), Nemec and Brinkhurst (1987), Brinkhurst and Gelder (1989), Gelder and Brinkhurst (1990), and Purschke et al. (1993) for further discussion on the phylogenetic relationships of the annelid groups. This paper follows the division of the phylum Annelida into two subphyla: the Aclitellata (Aphanoneura and Polychaeta), and the Clitellata (including the Acanthobdellida, Branchiobdellae, Oligochaeta, and Hirudinea). The relationship of the Aphanoneura to the Polychaeta, however, remains unresolved. Nomenclature follows Reynolds and Cook (1976, 1981, 1989, 1992). Nomenclatura Oligochaetologica: Supplementum Quartum - the fourth supplement to the Reynolds and Cook series, is currently being compiled by John W. Reynolds and Mark J. Wetzel; its publication is anticipated for 2002.
