A new species of the genus Aporcella collected from a watermelon field in Nigeria is described, including its morphological and molecular (small subunit (SSU) and large subunit (LSU) ribosomal DNA (rDNA)) characterization. Aporcella femina sp. n. is distinguished by its 3.21-3.64 mm-long body, inner cuticle layer with fine but distinct transverse striation, lip region offset by deep constriction, 22-25 µm broad, odontostyle 20-26 µm, neck 661-811 µm long, pharyngeal expansion occupying 52-56% of the total neck length, female genital system didelphic-amphidelphic, uterus 191-350 µm or 1.9-3.3 mid-body diameters long, V = 52-57, tail short and convex conoid (35-48 µm, c = 72-98, c' = 0.7-0.9) and males absent. Phylogenetic analyses based on the partial sequence of SSU and LSU (D2-D3) rDNA revealed a close relationship of A. femina sp. n. with other Aporcella species, confirming the monophyly of the genus as well as its association to a clade made of several taxa characterized by the absence of pars refringens vaginae.
