Steinernema boemarei n. sp. (Nematoda: Steinernematidae), a new entomopathogenic nematode from southern France
Systematic Parasitology 72 (2), 127-141
Abstract: A new entomopathogenic nematode, Steinernema boemarei n. sp., is described from southern France. Morphological, molecular (28S and ITS rDNA sequence data) and cross-hybridisation studies were used for diagnostics and identification purposes. Both molecular and morphological data indicate that the new species belongs to the `glaseri-group' of Steinernema spp. Key morphological diagnostic traits for S. boemarei n. sp. include the presence of prominent deirids (cervical papillae) on adult males, the morphology of the spicules and gubernaculum, and the arrangement of the 23 genital papillae of the first generation males. Additionally, morphometric traits of the third-stage infective juvenile, including total body length (mean 1,103 μm), tail length (mean 86 μm), location of the excretory pore (mean 91 μm), and D% (mean 63), E% (mean 106) and H% (mean 41) values are definitive. In addition to these morphological characters, analysis of both 28S and ITS rDNA sequences depict this Steinernema species as a distinct and unique entity.
