Specimens of a Longidorus species, here described as L. danuvii sp. n., were recovered from the rhizosphere of Amorpha fruticosa growing in a floodplain forest on the bank of the river Danube at Novi Sad, Serbia; a second population was collected from Populus sp. also at Novi Sad. Longidorus danuvii sp. n. is characterised by medium sized body length (3.7-5.4 mm), slightly expanded, anteriorly flattened and laterally rounded lip region, set off by a depression from the rest of the body, distinctly bilobed amphidial pouches with lobes of about equal length, medium odontostyle length (86-101 ? m) and elongate, conoid tail with more or less bent appearance. Four juvenile developmental stages were identified. A second Longidorus species, identified as L. silvae, was recovered from the rhizosphere of Quercus petraea at Rakovac, Fru?ka Gora mountain, Serbia. The discovery of two males is the second record for this species. PCR-RFLP analyses of the ITS containing regions and sequences of the D3 region of the 26S rDNA were done

Abstract
Specimens of a Longidorus species, here described as L. danuvii sp. n., were recovered from the rhizosphere of Amorpha fruticosa growing in a floodplain forest on the bank of the river Danube at Novi Sad, Serbia; a second population was collected from Populus sp. also at Novi Sad. Longidorus danuvii sp. n. is characterised by medium sized body length (3.7-5.4 mm), slightly expanded, anteriorly flattened and laterally rounded lip region, set off by a depression from the rest of the body, distinctly bilobed amphidial pouches with lobes of about equal length, medium odontostyle length (86-101 ? m) and elongate, conoid tail with more or less bent appearance. Four juvenile developmental stages were identified. A second Longidorus species, identified as L. silvae, was recovered from the rhizosphere of Quercus petraea at Rakovac, Fru?ka Gora mountain, Serbia. The discovery of two males is the second record for this species. PCR-RFLP analyses of the ITS containing regions and sequences of the D3 region of the 26S rDNA were doneI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
