Aporcella malekimilanii Naghavi, Niknam, Vazifeh & Pena-Santiago, 2019

Morphology and Anatomy:

Slender to very slender nematodes of medium size, 1.9-2.7 mm long.
Cuticle three-layered, especially distinguishable at caudal region
Lateral hypodermal chords 15-20 Î¼m wide, occupying 27-28% of corresponding body diam. and bearing glandular bodies.
Lip region slightly expanded, offset by a weak constriction, 21-23% of body diam. at neck base.
Amphid fovea cup-shaped, aperture occupying 56-73% of lip region diam.
Cheilostom almost cylindrical, lacking any differentiation.
Odontostyle typical of genus, 0.9-1.2 times lip region diam. aperture occupying 59-60% of its length.
Guiding ring simple, plicate.
Odontophore linear, rod-like, 1.9-2.0 times odontostyle length.
Esophagus with slender but muscular anterior region enlarging gradually and basal expansion 9.5-11 times longer than wide and occupying 58-63% of total neck length,
Cardia hemispheroid to conical, 12-16 Ã— 10-12 Î¼m.
Prerectum 2.5-3.0, rectum 1.1-1.3 times anal body diam. long.
Tail conical with finely rounded terminus, ventrally nearly straight, dorsally convex with a more or less (often) conspicuous dorsal concavity at its posterior part, inner cuticle layer with a discontinuity (gap) at tail tip, appearing as a terminal hyaline portion at end
Two pairs of caudal pores present.

Female:

Female gonad diovarial, amphidelphic; vulva transverse.-
Ovaries generally not reaching oviduct-uterus junction and with oocytes first in two or more rows and then in a single row,
Oviduct 1.6-2.0 times corresponding body diam., consisting of a slender part with prismatic cells and a poorly developed pars dilatata with a small lumen, oviduct and uterus separated by a weak sphincter, uterus a simple, tube-like structure 1.2-1.5 body diam. long;
Vagina perpendicular to body axis, extending inwards less than one-half (40-45%) of body diam., with pars proximalis 16-18 Ã— 8-9 Î¼m and sigmoid walls surrounded by weak circular musculature, pars refringens absent, and pars distalis 6-8 Î¼m long,
Vulva transverse slit.
