Description
Genus Pseudosteineria Wieser, 1956
Type species: Pseudosteineria anteferens Wieser, 1956.
Diagnosis (emended after Wieser 1956 and Tchesunov 2000). Xyalidae. Body spindle-shaped. Cuticle distinctly annulated. Lateral differentiation may be present as lateral fields. Anterior sensilla in two crowns (6 + 12) with the second crown composed of six anterior outer labial sensilla, four posterior cephalic sensilla, and two additional lateral sensilla. Long subcephalic (cervical) setae, arranged in six or eight groups about the level of the amphids, at some distance posteriorly to the cephalic capsule. In each group several subcephalic setae arranged in a short longitudinal row where the setae gradually increase in length posteriorly. Other somatic setae can be short or very long, scarce or abundant, and irregularly distributed along the body. Amphideal fovea circular, just before, just behind or at the level of subcephalic setae. Buccal cavity conical. Copulatory apparatus variable in shape. Tail conico-cylindrical, consisting of proximal conical and slender cylindrical distal parts. Tail tip slightly inflated and provided with long terminal setae.
