AbstractMorphologial, biochemical, molecular and karyological analyses of different populations and races of the stem and bulb nematode Ditylenchus dipsaci have suggested that it represents a species complex, of which only D. dipsaci sensu stricto and its morphologically larger variant, known as the giant race of the stem and bulb nematode, are plant parasites of economic importance. The present study singles out the giant race from this complex, herein described as a new species named Ditylenchus gigas n. sp., on the basis of morphological and molecular data obtained from several populations collected from broad beans in southern Italy, southern Spain and Lebanon. The new species epithet, which refers to the large body size of the nematode with respect to the normal races, must be considered to be conspecific with the D. dipsaci'giant race' from Fabaceae in recent literature. Morphologically, the new species is characterized by a body size 1·5-2 times longer than the 'normal race', stylet delicate (11·5-13·0μm long) with knobs distinctly sloping backwards, and long post-vulval uterine sac (81-150μm long). Results of molecular analysis of rDNA sequences including the ITS1-5.8S-ITS2 region, the D2-D3 fragment of the 28S gene, the small 18S subunit, the partial mitochondrial gene for cytochrome c oxidase I (mtCOI), and hsp90 gene sequences, support the new taxonomic species status for the former D. dipsaci giant race from Vicia faba, and clearly distinguish D. gigas n. sp. from D. dipsaci sensu stricto. © 2011 The Authors.
