Teranishia Tsuneki, 1991: 15; Lelej 1995: 12; 2003: 3; Carmean and Kimsey 1998: 73. Type species (by original designation): Teranishia nipponica Tsuneki, 1991.

Diagnosis.

Length of body 6.0-12.0 mm; antenna black and with 24-27 segments; area above supra-antennal elevations flat, more or less punctate, with protuberance between elevations and inner side of supra-antennal elevations flat, smooth and black (Figs 595, 606); tyloids on 11 th– 14th antennal segments of male absent; 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. 595); mandibles wide in anterior view and sublaterally attached to head (Fig. 594); anterior propodeal sulcus distinctly crenulate (Fig. 599); metanotum strongly convex and finely sculptured medially (Fig. 599); anterior propodeal sulcus crenulate and medially widened (Figs 599, 610); posterior propodeal carina curved and distinctly protruding and more or less separated from foramen medio-dorsally (Figs 599, 610); fore wing with large dark patch below pterostigma; vein 1-SR of fore wing long (Figs 597, 608); hind trochanter black, dark brown or ivory; hind tarsus slightly or not modified; second and third sternites of ♀ flat and moderately sclerotized and no protuberances (Fig. 603); body without pale pattern, at most malar space and margins of basal metasomal sternites and tergites narrowly ivory, remainder black.

Notes.

According to Lelej (2003) the female paratypes (not male holotype) of Teranishia nipponica belong to Teranishia marujamae Tsuneki, 1991. However, in the original description of Teranishia nipponica is indicated that the supra-antennal elevations have a medial yellow spot, which is absent in the holotype of Teranishia marujamae ; therefore, we refrain from accepting this synonymy.
