Aporcella charidemiensis sp n. (Dorylaimida: Aporcelaimidae) from the southern Iberian Peninsula, with comments on the phylogeny of the genus

Aporcella charidemiensis sp. n. is described from the southern Iberian Peninsula. It is characterised by its 1.38-1.81 mm long body, lip region offset by constriction and 16-17 mu m broad, odontostyle 12-13 mu m long with aperture occupying 65-73% of its length, 354-420 mu m long neck, pharyngeal expansion 164-212 mu m long or 46-51% of total neck length, uterus a simple tube-like structure 79-155 mu m long or 1.7-3.0 times the corresponding body diam., pars refringens vaginae absent, transverse vulva (V = 53-62), convex conoid tail (24-35 mu m, c = 46-69, c' = 0.8-1.1), 59-63 mu m long spicules, and 7-10 irregularly spaced ventromedian supplements bearing a hiatus. The analyses of LSU-DNA sequences of the new species confirm the previous results regarding the phylogeny of the genus Aporcella.
