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

Abstract

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 μm broad, odontostyle 12-13 μm long with aperture occupying 65-73% of its length, 354-420 μm long neck, pharyngeal expansion 164-212 μm long or 46-51% of total neck length, uterus a simple tube-like structure 79-155 μm 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 μm, c = 46-69, c′ = 0.8-1.1), 59-63 μm 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 .
