Interpretive Summary:

Technical Abstract: Oscheius wisconsinensis n. sp. (Rhabditidae) was recovered through the Galleria bait method from a wild cranberry marsh in Jackson County, Wisconsin, USA. Morphological studies with light microscopy and scanning electron microscopy, as well as molecular analyses of the near-full-length small subunit rDNA gene (SSU), D2/D3 expansion segments of the large subunit rDNA gene (LSU), internal transcribed spacer (ITS), and mitochondrial cytochrome oxidase subunit 1 (CO1) genes revealed this as a new species, described herein as Oscheius wisconsinensis n. sp. The new species is characterized by its unique DNA sequences; hermaphroditic reproduction; male absent. Oscheius wisconsinensis n. sp. belongs to the dolichura-group. A Bacillus-like bacteria appears to be associated with this nematode based on our microscopic and SEM observations. Preliminary tests revealed that this nematode is capable of infecting Blattodea, Coleoptera, and two families of Lepidoptera under laboratory conditions; therefore, it has potential as a biological control agent.
