F3 length 2.35–2.80 × its width; F4 length 2.35–2.90 × its width; penultimate flagellomere length 1.50–2.00 × its width; occipital carina with a very small interruption dorsally; OOL 0.32–0.59 × OD; OD 0.84–1.16 × POL ( Fig. 22 ); eye length (in dorsal view) 1.71–2.22 × temple; head height 1.28–1.37 × eye height ( Fig. 21 ); malar space 0.41–0.53 × basal mandible width; minimum width of face 0.75–0.90 × its maximum width; minimum width of face 0.87–1.05 × its height ( Fig. 20 ); head mostly smooth except clypeus and face slightly rugulose.

Mesosoma: Pronotum mostly smooth, pronotal sides carinate medially; mesonotal lobes smooth; notauli complete, carinate anteriorly, carinate-rugose posteriorly; scutellum smooth; scutellar sulcus smooth with five carinae; mesopleuron smooth; precoxal sulcus complete, mostly smooth with some short carinae ( Fig. 23 ); metapleuron smooth, with borders rugose; propodeum carinate-rugose ( Fig. 24 ); mesosoma length 1.31–1.53 × its height.

Wings: Fore wing length 3.72–4.46 mm; vein r 0.09–0.16 × 3RS; vein 1CUa 0.27–0.41 × 1CUb; vein m-cu of fore wing antefurcal.

Metasoma: T1 Rugulose, its length 1.31–1.61 × its apical width; ovipositor gradually curved downwards ( Fig. 27 ); ovipositor 0.54–0.74 × metasoma length.

Male. Similar to female except: Body length 3.03–3.10 mm; antenna with 25–26 flagellomeres; F1 length 3.33–3.40 × its width; F2 length 3.00–3.20 × its width; F3 length same as F4; F3 length 3.00 × its width; F4 length 3.00 × its width; penultimate flagellomere 1.60–1.75 × its width; OOL 0.50–0.60 × OD; OD 0.80–0.91 × POL; eye length (in dorsal view) 1.93–2.07 × temple; head height 1.23–1.37 × eye height; malar space 0.36–0.50 × basal mandible width; minimum width of face 0.76–0.83 × its maximum width; minimum width of face 0.95 × its height; wing length 3.16–3.28 mm; vein r 0.15–0.17 × 3RS; vein 1CUa 0.30–0.38 × 1CUb; mesosoma length 1.32–1.35 × its height; femur length 5.54–6.77 × its width; tibia length 7.10–8.50 × its width; basitarsus length 3.50–3.69 × its width; hind tarsus “normal” (i.e. without spine in third tarsomere); T1 length 1.42–1.64 × its apical width.

Comments. Pygostolus odeterochae sp. nov. is more similar to P. falcatus , both have antenna with around 25–31 flagellomeres, ovipositor curved downwards and dorso-posterior part of pronotal sides largely smooth, but P. odeterochae sp. nov. could be easily distinguished by having the body mostly yellow with head black dorsally, wings somewhat infuscate, ocelli larger (OD 0.80–1.16 × POL) and hind leg (in females) with third tarsomere modified, with a distinctive spine apically ( Fig. 26 ).

Distribution. Brazil; Parana and Para state.

Etymology. This species is named after Odete rocha, in recognition for her comments in an early version of this paper.
