Taxonomic Value of the Position of Oesophageal Gland Nuclei and of Oesophageal Gland Overlap in the Trichodoridae (Diphtherophorina)

Taxonomic Value of the Position of Oesophageal Gland Nuclei and of Oesophageal Gland Overlap in... TAXONOMIC VALUE OF THE POSITION OF OESOPHAGEAL GLAND NUCLEI AND OF OESOPHAGEAL GLAND OVERLAP IN THE TRICHODORIDAE (DIPHTHEROPHORINA) BY W. DECRAEMER(*) & D. DE WAELE Laboratorium voor Morfologie en Systematiek der Dieren, Rijksuniversiteit Gent, Ledeganckstraat 35, B-9000 Gent, Belgium Within the Trichodoridae the diagnostic value of 1) the position of the oesophageal gland nuclei, 2) the overlapping of the intestine by the posterior ventro-sublateral oesophageal glands and 3) that of the front end of the intestine over the rear of the oesophagus, was examined; none was reliable. Atlantadorus Siddiqi, 1974 and Nanidorus Siddiqi, 1974 are junior synonyms of Paratrichodorus. In the suborder Diphtherophorina Coomans & Loof, 1970 the pyriform to elongated oesophageal bulb possesses one dorsal and at least two ventro- sublateral uninuclear glands. Most species have one gland in the dorsal sector and two pairs in the ventro-sublateral sector. This article deals with the position of the oesophageal gland nuclei and the location of the glandular outlets within the Trichodoridae (Thorne, 1935) Clarke, 1961, Diphtherophorina Coomans & Loof, 1970, Dorylaimida, and examines the diagnostic value of the overlap or non-overlap of the intestine by the posterior ventro-sublateral oesophageal glands (oesophageal gland overlap or OL) and whether the http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nematologica Brill
