Polysphincta dizardi Gauld, 1991: 313. Holotype ♀, Costa Rica (MNCR).

Diagnosis.

Polysphincta dizardi can be distinguished from other species of the P. dizardi species-group by the combination of the following characters: (1) epomia absent (Fig. 3B ); (2) malar space 0.45-0.5 times as long as proximal mandibular width (Fig. 3B ); (3) fore wing vein 1 cu-a interstitial relative to M&RS (Fig. 3A ); (4) mesosoma reddish brown with anterior part of pronotum, propleuron, metapleuron and propodeum blackish (Fig. 3A ); (5) wings hyaline (Fig. 3A ); (6) hind leg whitish with femur laterally, tibia proximally and distally, and tarsus distally brownish (Fig. 3A ); (7) metasoma entirely darkish brown (Fig. 3A, C ); (8) ovipositor slender, 1.1-1.3 times as long as hind tibia.

Comments.

Additional characters to the original description (♀) are as follows: body about [7.7-8.3] 7.5-8.5; head in dorsal view with margin of the gena convex behind the eyes, and its margin [0.5-0.55] 0.45-0.55 times length of eye; shelf-like projection, in dorsal view, more or less developed anterolaterally, apex very weakly bilobed, and in lateral view, with anterolateral part of apex rounded and very weakly decurved; mesoscutum robust, in dorsal view; tarsal claw with proximal lobe quadrangular, with claw apex slightly overtaking distal margin of lobe.
