Name

Jezonogonalos Tsuneki, 1991 re-instated – Wikispecies link – Pensoft Profile

• Jezonogonalos Tsuneki, 1991: 32, 2003: 4; Carmean and Kimsey 1998: 70. Type species (by original designation): Jezonogonalos marujamanae Tsuneki, 1991 [= Jezonogonalos marujamae Tsuneki, 1991]. Synonymized with Pseudogonalos Schulz, 1906, by Lelej 1995.

Diagnosis

Length of body 6.6–12.0 mm; antenna black and with 23–27 segments; area above supra-antennal elevations flat, more or less punctate, without protuberance between elevations and inner side of supra-antennal elevations flat, smooth and black (Figs 40, 55, 66, 75, 87, 98); tyloids on 11th–14th antennal segments of male short and nearly circular or elliptical (Figs 51, 56, 77, 100; unknown of Jezonogonalos laeviceps and Jezonogonalos nigrata sp. n.); 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 (Fig. 75); mandibles wide in anterior view and sublaterally attached to head (Fig. 39); metanotum strongly convex and finely sculptured medially (Fig. 59); anterior propodeal sulcus crenulate and medially widened (Fig. 59); posterior propodeal carina curved and distinctly protruding and more or less separated from foramen medio-dorsally (Figs 44, 59, 69, 80, 93, 103); fore wing with large dark patch below pterostigma; vein 1-SR of fore wing long (Figs 42, 57, 68, 78, 89, 101); hind trochanter black or ivory; hind tarsus slightly or not modified; second and third sternites of + flat and moderately sclerotized and no protuberances (Figs 48, 72, 95, 107); body without pale pattern, at most malar space and margins of basal metasomal sternites and tergites narrowly ivory, remainder black.

Biology

Unknown.

Notes

Jezonogonalos Tsuneki was treated as valid genus in the revision by Carmean and Kimsey (1998) and synonymized with Pseudogonalos Schulz by Lelej (1995). We agree with Carmean and Kimsey (1998) that the shape of the supra-antennal elevations is different enough to retain both genera as valid.
