On the molecular identity of <i>Paratylenchus nanus</i> Cobb, 1923 (Nematoda: Tylenchida)

Abstract

In this study, molecular characterization of <i>Paratylenchus nanus</i> collected from the type locality in Four Mile Run, Fall Church, Virginia using <i>COI,</i> D2-D3 of 28 S rRNA and ITS rRNA gene sequences was provided. We molecularly also characterized, <i>Paratylenchus</i> specimens collected from grasses in Devils Lake, Ramsey County, North Dakota indicated as the type locality in the original description of <i>P. nanus</i> by Cobb (1923). These nematodes were identified as representatives of the species <i>P. projectus.</i> Populations of <i>P. nanus</i> belonging to the molecular types A and B, and previously designated by Van den Berg et al. (2014) should be now identified as <i>P. nanus</i> and <i>P. projectus</i>, respectively.
