Pleuronema setigerum Calkins, 1902

Remarks and comparison

Kahl (1931) redescribed this species, and Borror (1963a) described its infraciliature but gave only a diagram of the buccal morphology. Pan et al. (2010) offered improved diagnoses of this species based on a Chinese population. Cells of the North American population matched previous descriptions of the species in all morphological characters, except body size in vivo (50–70 × 25–35 μm vs 30–50 × 15–30 μm).
