PARALONGIDORUS-IBERIS SP-N AND PARALONGIDORUS-MONEGRENSIS SP-N FROM SPAIN WITH A POLYTOMOUS KEY TO THE SPECIES OF THE GENUS PARALONGIDORUS SIDDIQI, HOOPER AND KHAN, 1963 (NEMATODA, LONGIDORIDAE)

Species of the genus Paralongidorus were found for the first time in S pain near Serreta Negra (Huesca), in the North-West of the country. Tw o new species, P. iberis sp.n. and P. monegrensis sp.n., are described . P. iberis sp.n. is characterized by its medium size (4.4-4.9 mm), ro unded set off lip region, stirrup-shaped amphidial pouch and conical d orsally convex tail with conical terminus. It is close to P. lemoni fr om which it differs in tail shape, presence of males, body length, pos ition of guiding ring, and a and c ratios. P. monegrensis sp.n. is cha racterized by its large body size (7.5-12 mm), hemispherical expanded lip region, stirrup-shaped amphidial pouch, and conical dorsally conve x tail with rounded terminus. It resembles P. sandellus and P. xiphine moides. It differs from P. sandellus by its longer body and odontostyl e and anterior position of guiding ring, and from P. xiphinemoides by presence of males, odontostyle length, position of guiding ring, and c ' ratio. A polytomous key of the 70 species described in the genus is proposed and two new combinations are proposed, P. sativus (Soni & Nam a, 1983) n. comb. and P. wiesae (Heyns, 1994) n. comb.
