Jezonogonalos Tsuneki, 1991: 32, 2003: 4; Carmean and Kimsey 1998: 70; Chen et al. 2014: 22-44 (diagnosis, key). Type species: Jezonogonalos marujamanae Tsuneki, 1991 [= J. marujamae Tsuneki, 1991], by monotypy. Synonymized with Pseudogonalos Schulz, 1906, by Lelej (1995) and re-instated by Chen et al. (2014).

Diagnosis.

Length of body 6.2-12.0 mm; antenna black and with 23-27 segments; area above supra-antennal elevations flat, more or less punctate, without protuberance between elevations right after inner side of supra-antennal elevations flat, smooth and black; tyloids of male antenna present on 10th-16th segments, short and nearly circular or elliptical; occipital carina widened medio-dorsally; apical segment of labial palp widened and obtuse, more or less triangular; vertex normal, at most with slight median depression dorsally; mandibles wide in anterior view and sublaterally attached to head; metanotum strongly convex and finely sculptured medially; anterior propodeal sulcus crenulate and medially widened; posterior propodeal carina curved and distinctly protruding and more or less separated from foramen medio-dorsally; fore wing with large dark patch below pterostigma; vein 1-SR of fore wing long; hind trochanter black or ivory; hind tarsus slightly or not modified; second and third sternites of female flat and moderately sclerotized and no protuberances; body rarely with pale pattern, at most malar space, basal segments and margins of metasomal sternites and tergites partly ivory, remainder black ( Chen et al. 2014).
