Aporcella simplex (Thorne & Swanger, 1936) Alvarez-Ortega, Subbotin & Pena-Santiago, 2013

Originally described as Aporcelaimus simplex by Thorne and Swanger (1936) and transferred to Aporcella by Alvarez-Ortega et al. (2013) on the basis of the nature of the cuticle, the absence of pars refringens vaginae and other characteristics.

Morphology and Anatomy:

Body length 1.74-2.29 mm; moderately slender.
Cuticle of two layers differing in refrqaction.
Labial region offset from body contour by a slight expansion of the lips rather than a deep constriction.
Odontostyle short and thick, 3.8-4.5 times as long as wide, length about 0.8-1x lip-region diam; aperture about 74-80% of odontostyle length.
Odontophore straight, rod-like, about 1.9-2.2x length of odontostyle.
Enlarged portion about 50-56% of total length of esophagus.
Tail similar in both sexes; short, conoid with slightly rounded base, about 1 abd long..

Female:

Female gonad diovarial, amphidelphic; vulva transverse.-
Intermediate part of vaginal canal without sclerotized pieces - (pars refringens vaginae absent).

Males: not found in Alvarez-Ortega et al (2013) sampling of Iberian peninsula
