Polysphincta shabui Gauld, 1991: 314. Holotype ♀, Costa Rica (MNCR).

Diagnosis.

Polysphincta shabui can be distinguished from other species of the P. dizardi species-group by the combination of the following characteristics: (1) epomia absent (Fig. 8B ); (2) malar space 0.6 times as long as proximal mandibular width (Fig. 8B ); (3) fore wing vein 1 cu-a more or less interstitial relative to M&RS (Fig. 8A ); (4) mesosoma entirely reddish brown (Fig. 8A ); (5) wings hyaline (Fig. 8A ); (6) hind leg orange with femur, tibia and tarsus darkish brown (or femur reddish orange) (Fig. 8A ); (7) metasoma entirely darkish brown or darkish brown with tergites I-III reddish orange with posterior margins narrowly black (Fig. 8A, C ); (8) ovipositor slender, 1.2-1.4 times as long as hind tibia.

Comments.

Additional characters to the original description (♀) are as follows: body about [10.5-11.0] 10.5-14.0; head in dorsal view with margin of the gena flat behind the eyes, and its margin [0.5] 0.5-0.6 times length of eye; shelf-like projection, in dorsal view, developed anterolaterally in apex, the apex bilobed, and in lateral view, with anterolateral part in apex rounded and weakly decurved; mesoscutum robust, in dorsal view; tarsal claw with proximal lobe quadrangular, with claw apex slightly overtaking the distal margin of lobe.

Distribution.
