INTRODUCTION
Over my career to date, I have presented 116
papers on state, provincial and territorial surveys and
checklists for North America. This paper summarizes
those papers, with references to the individual checklist
papers. Data collected or records received since the
individual checklists were published are located in
APPENDIX I, Table 1. (pp. 62–63). The geographical
location of the Canadian provinces and territories are
shown in APPENDIX II (Fig. 1, p. 64) and the American
states in APPENDIX III (Fig. 2, p. 65).

MEGADRILOGICA 61
DISCUSSION
One of the significant problems with surveys,
checklists, etc. is that the day they are printed, or soon
afterwards, they are out of date! To help alleviate this
problem, Appendix I, Table 1 (pp. 63–64) includes
species in a given jurisdiction where the information has
been received since the checklist or survey paper was
published.
Currently, the checklist and surveys of Canada
and the United States contain a total of ten families1, 432
genera, and 193 species.
Eventually, there may be sampling, or
additional sampling, in these under-collected juris-
dictions to determine the presence and distribution of
earthworms in these areas, e.g., American states of
Alaska, Idaho, Iowa, Kansas, Nebraska, west Texas,
Wisconsin; in Canada Manitoba and Saskatchewan, plus
the Northwest, Nunavut and Yukon territories.

ABSTRACT The Southern California/Northern Baja Coast Ecoregion in the United States occurs in portions of seven counties in the state of California. There are 21 species found here in 12 genera and four families (Acanthodrilidae, Lumbricidae, Megascolecidae and Ocnerodrilidae ). Six of the species are native (endemic) to North America; all others are European, Oriental, or Pantropical (exotic) introductions. A description of the ecoregion and two colour photographs are also included. Key-words: Southern California/Northern Baja Coast Ecoregion, Oligochaeta, Acanthodrilidae, Lumbricidae, Megascolecidae, Ocnerodrilidae, earthworms, distribution

ABSTRACT The Central California Foothills and Coastal Mountains Ecoregion in the United States occurs in portions of 28 counties in the state of California. There are 22 species found here in 13 genera and five families (Acanthodrilidae, Lumbricidae, Megascolecidae, Ocnerodrilidae and Sparganophilidae). Six of the species are considered native (endemic) to North America (Bimastos parvus, Bimatos tumidus, Argilophilus marmoratus, Argilophilus papillifer, Sparganophilus eiseni and Sparganophilus pearsei); all others are European, Oriental or Pantropical introductions (exotic). A description of the ecoregion and nine colour photographs are also included. Key-words: Klamath Mountains/California High North Ecoregion, Oligochaeta, Acanthodrilidae, Lumbricidae, Megascolecidae, Ocnerodrilidae, Sparganophilidae, earthworms, distribution

This survey of the earthworms from 44 of the 77 counties of Oklahoma, USA, recorded 30 species of terrestrial Oligochaeta. Eighteen of these species, Acanthodrilidae: Megascolecidae: Amynthas agrestis, A. diffringens and A. hupeiensis are reported for the first time from the state, plus three species of Diplocardia new to science. Thirty-two of the counties in the state report earthworms for the first time. Current nomenclature is applied to historical records of earthworms presented in the literature.

This survey of the earthworms from all 37 east Texas counties within the Piney Woods Ecoregion recorded 51 described species and six species new to science of terrestrial Oligochaeta bringing the number of known species to 57. Twenty-six species are reported from Texas for the first time: Acanthodrilidae: Diplocardia biprostatica, D. bivesiculata, D. caroliniana, D. conoyeri, D. eiseni, D. hulberti, D. longiseta, D. macdowelli, D. ornata, D. pettiboneae, D. riparia, D. rugosa, D. singularis, D. sylvicola, Microscolex dubius, and M. phosphoreus, Lumbricidae: Bimastos heimburgeri, Dendrodrilus rubidus, Lumbricus rubellus, L. terrestris, and Octolasion tyrtaeum, and Megascolecidae: Amynthas agrestis, A. hawayanus, A. hilgendorfi, A. hupeiensis, and Perioynx shillongensis, plus six undescribed species of Diplocardia new to science. Current nomenclature is applied to historical records of earthworms presented in the literature.

This survey of the earthworms from 51 of the 87 counties of Minnesota recorded 15 species of terrestrial Oligochaeta, five of which are reported for the first time from the state: Acanthodrilidae (Diplocardia riparia), Lumbricidae (Allolobophora chlorotica, Bimastos parvus, and Eiseniella tetraedra) and Megascolecidae (Amynthas loveridgei). The distribution of the earthworm species appears to be mildly influenced by the three physiographic regions found within the state: 1) Northern Lakes States Forest and Forage Subdivision, 2) Central Feed Grains and Livestock Subdivision and 3) Northern Great Plains Spring Wheat Subdivision.
