Abstract

Laimydorus Siddiqi, 1969 species and description of Chrysodorus longicaudatus gen. et sp. n. (Nematoda, Dorylaimidae) of the River Guadalquivir basin (Spain)
Laimydorus pseudostagnalis, Laimydorus cf. L. prolificus and Laimydorus cf. L. serpentinus new records for Spain, are described from populations found in the basin of the Guadalquivir River and their diagnostic charactenstics discussed. Chrysodorus n. gen. is proposed to accommodate those species of Laimydorus and Mesodorylaimus with body long and slender (L about 3-4 mm, a = 60-95), lip region truncate and odontostyle attenuated. C. longicaudatus n. sp. is described and designated type species; it differs from C. lordelloi (Meyl, 1957) n. comb. and C. dhanachandi (Jairajpuri & Ahmad, 1982) n. comb. in body size, odontostyle, female tail, spicules and the ventro-median contiguous supplements of the male.
