Description of female. Body length: 5.51–6.82 mm.
Coloration: Body mostly yellowish brown except metasoma with T2–T8 yellow, stematicum and tarsus brown and flagellum and ovipositor sheaths dark brown; stigma yellowish-light brown.
Head: Antenna with 31–33 flagellomeres; F1 length 2.60–2.90 × its width; F2 length 2.40–3.10 × its width; F3 with same length as F4; F3 length 2.52–2.95 × its width; F4 length 2.50–3.00 × its width; penultimate flagellomere 1.33–1.62 × its width; occipital carina complete, some specimens with a small interruption dorsally; OOL 0.36–0.66 × OD; OD 0.63–1.06 × POL; eye length (in dorsal view) 1.50–1.85 × temple; head height 1.21–1.46 × eye height; malar space 0.47–0.60 × basal mandible width; minimum width of face 0.81–0.88 × its maximum width; minimum width of face 0.95–1.05 × its height; head smooth.
Mesosoma: Pronotum mostly smooth, pronotal sides carinate medially; dorso-posterior part of pronotal sides unsculptured ( Fig. 14 View FIGURES 9–14 ); mesonotal lobes smooth; notauli complete, carinate anteriorly, carinate-rugose posteriorly ( Fig. 13 View FIGURES 9–14 ); scutellum smooth; scutellar sulcus smooth with four or five carinae; mesopleuron smooth and shining above precoxal sulcus, puncticulate below ( Fig. 14 View FIGURES 9–14 ); precoxal sulcus complete, carinate; metapleuron rugose, almost smooth medially in some specimens; propodeum rugose to carinate-rugose with two rugulose areas anteriorly; mesosoma length 1.37–1.50 × its height.

Metasoma: T1costate or faintly costate with a smooth area centrally ( Fig. 15 View FIGURES 15–18 ), its length 1.50–1.81 × its apical width; ovipositor gradually curved downwards, its length 0.59–0.88 × metasoma length.
Male. Similar to females, except: Body length 4.15–5.58 mm; antenna with 29–31 flagellomeres; OOL 0.46 × OD; OD 0.86–0.94 × POL; eye length (in dorsal view) 1.41–1.55 × temple; head height 1.34–1.48 × eye height; malar space 0.45–0.60 × basal mandible width; minimum width of face 0.84–0.88 × its maximum width; minimum width of face 0.93–1.23 × its height; clypeus and face rugulose; fore wing length 3.84–5.33 mm; vein r 0.13–0.15 × 3RS; vein 1CUa 0.27–0.37 × 1CUb; mesosoma length 1.28–1.35 × its height; femur length 4.20–4.61 × its width; tibia length 7.75–10.30 × its width; basitarsus length 4.57–4.66 × its width; T1 length 1.48–1.61 × its apical width.
Comments. Pygostolus carolinae sp. nov is more similar to P. falcatus . Both species have the dorso-posterior part of pronotal sides largely smooth, ovipositor sheath comparatively slender and ovipositor distinctly bent downwards. The new species can be distinguished mainly by its larger eyes and ocelli: malar space 0.45–0.60 × basal mandible width and OOL 0.36–0.66 × OD.
The larger specimens of P. carolinae sp. nov. also resemble, P. sticticus and P. multiarticulatus , due to having a similar color, body size and number of flagelomeres. The new species can be distinguished from booth of these by having the dorso-posterior part of pronotal sides unsculptured. The new species can also be easily distinguished from P. sticticus by having the ovipositor longer, clearly curved downwards and with its apex slender ( Fig. 17 View FIGURES 15–18 ).
Distribution. Brazil; Parana, Santa Catarina and Sao Paulo state.
Etymology. This species is named after Carolina Reigada Montoya , in recognition for her comments in an early version of this paper.
