Description of Trichodorus variabilis n. sp. (Nemata: Diphterophoroidea) from Greece

Trichodorus variabilis n. sp. is described and illustrated. It was found during a survey of Longidoridae at Kato Souli, Marathon area, Greece, around roots of artichoke. The new species is characterized by two ventromedian cervical papillae posterior to the onchiostyle region, in a variable location with respect to the secretory-excretory pore, shape of spicules with widened manubrium gradually merging with a slender and equally wide calomus in males, and barrel-shaped vagina with small triangular sclerotized pieces and a pair of postadvulvar lateral body ports in female. T. variabilis sp. n. closely resembles T. giennensis Decraemer et al., 1993 and T. sparsus Szczygiel, 1968. (C) Elsevier - ORSTOM.
