Nevadanema uniforme (Thorne, 1939) Alvarez-Ortega & Pena-Santiago, 2012

Synonyms:

Labronema uniforme Thorne, 1939

Morphology and Anatomy:

Moderately slender, large nematodes, 3.4 mm long.
Body cylindrical, tapering towards anterior end.
Cuticle two-layered, outer layer thinner than inner one; inner layer with conspicuous radial striation.
Two ventral pores present in anterior region at level of odontostyle,
Lateral chord occupying one-third of mid-body diam.
Lip region rounded, offset by constriction, 2.9 times as broad as high and 25-33% of body diam. at neck base.
Lips almost amalgamated, papillae not extending above lip region contour.
Cheilostom nearly cylindrical.
Odontostyle comparatively long and slender,1.6 times as long as lip region diam., aperture 20% of length.
Guiding ring double.
Esophagus enlarging very gradually, basal expansion 66% of total neck length.
Prerectum 3-5 anal body diam. long.
Tail 41 Î¼m long, short, rounded.
Two pairs of caudal pores at middle of tail, one dorsal, one subdorsal.

Note: Lip region and odontostyle morphology very similar to that of Nevadanema nevadense and quite different from those of the genus Labronema.

Female:

Genital system didelphic-amphidelphic, with both branches equally developed.
Vulva a post-equatorial, transverse slit.

Males: Unknown.
