Earthworms (Oligochaeta: Acanthodrilidae and Lumbricidae) associated with Hornsby Bend Biosolids Management Plant, Travis County, Texas, USA
Earthworm populations were surveyed in soils from a variety of habitats associated with the Hornsby Bend Biosolids Management Plant, Austin, Texas, from November 2009 through March 2010. Seven species of terrestrial Oligochaeta, including one species new to science, are reported from two families, each represented by one genus: Acanthodrilidae: Diplocardia caroliniana, D. fusca, D. invecta, D. smithii, D. sp. nov., and Lumbricidae: Aporrectodea rosea and Ap. trapezoides. Additional oligochaete specimens, mostly diplocardians, were also collected but species identification was not possible. Invasive Asian species of earthworms were not observed. Ap. rosea was the only prominent nonnative invasive earthworm species found in the soils of Hornsby Bend Biosolids Management Plant during this survey.
