Nematodes of the order Dorylaimida from Andalucía Oriental, Spain. Nevadanema nevadense gen. n., sp. n. (Qudsianematidae) from Sierra Nevada National Park

Abstract

Nevadanema nevadense gen. n., sp. n. is described from natural highlands in the south-eastern Iberian Peninsula and is characterised on the basis of morphological, morphometric and molecular (D2/D3-LSU rDNA) data, including SEM study. The new genus is mainly distinguishable by its rounded and offset lip region with amalgamated lips, odontostyle comparatively attenuated, guiding ring double, odontophore rod-like, female genital system amphidelphic, pars refringens vaginae present, and short and rounded tail. It is morphologically close to Labronema, from which it differs in the nature of the lip region and odontostyle. Two species of Labronema, namely L. fimbriatum and L. uniforme, are transferred to the new genus.
