- Abstract
Paralongidorus francolambertii sp. n., a bisexual species found in the rhizosphere of silver lime (Tilia tomentosa) and common juniper (Juniperus communis), is described. The species is characterised by its medium to large size (L = 5.86-8.29 mm) and slender body (a = 143-197), a lip region flattened with rounded profile, clearly offset from the body by a deep constriction, a narrow neck between the head and body, a shoulder-like body posterior to the neck, a stirrup-shaped amphidial fovea, with conspicuous slit-like aperture, lying on the lateral cuticular collar, a moderately long odontostyle ca 140 µm long, a guide ring located at ca 28 µm from anterior end, a tail terminus with thickened outer cuticular layer in both sexes, and males with spicules ca 52 µm long. The D2-D3 expansion domains of the 28S rRNA gene and the ITS-containing region of P. francolambertii sp. n. were amplified and sequenced. Phylogenetic analyses by using the Maximum Likelihood method showed that P. francolambertii sp. n. had a sister relationship with P. rex and that all Paralongidorus species formed a well-supported group.
