Diagnosis
Handaoia fritzi sp. nov. can be distinguished from all other New World species by the combination of the following characters: apophysis of propodeum as a low transverse rounded or slightly pointed triangular crest (Fig. 3G, arrow); juxtacoxal carina strong, irregular, joining submetapleural carina at anterior 0.3–0.4 (Fig. 3F, arrow); area externa of propodeum separated from area dentipara by strong carina (Fig. 1B); inner side of area externa 3.0–3.4 × as long as inner side of area dentipara (Fig. 1B); inner side of area dentipara 0.46–0.5 × the length of outer side (Fig. 1B); tergite II smooth and shiny (Fig. 3B).
Etymology
This species is named in honour of Dr Fritz Plaumann, illustrious botanist and entomologist based in Brazil, who collected the type material. A noun in genitive case.

Description
Female
MEASUREMENTS. Body length (without ovipositor) 3.3–4.1 mm. Fore wing 2.7–3.3 mm long.
HEAD. Finely granulate, matt, distinctly narrowed behind eyes, occiput very concave centrally in dorsal view (Fig. 3C); gena 0.2–0.25 × length of eye in dorsal view; posterior ocellus separated from eye by 0.75–1.25 × its own maximum diameter; distance between posterior ocelli 0.75–1.0 × maximum ocellar diameter (Fig. 3C); occipital carina gently V-shaped medially (Fig. 3B); malar space 1.15–1.25 × basal width of mandible; face slightly swollen medially; clypeus (Fig. 3E) weakly convex, faintly granulate dorsally, smooth and shiny ventrally, with scattered punctures, its apex almost straight, 2.1–2.2× as wide as high; mandible slightly tapered to apex, ventral tooth of mandible approximately same length as upper tooth; maxillary palp relatively short, reaching at most ⅔ length of mesosternum; flagellum widened in middle, tapered towards apex, flagellomeres 8–17 flattened ventrally; flagellum with 19–20 segments, length-thickness ratios: 1 st segment = 4.74–5.0, 2 nd = 5.0–5.28 and 10 th = 1.0.
MESOSOMA. Finely granulate and matt (Fig. 3B–D); mesoscutum convex, notauli weak anteriorly, reaching about 0.3 distance to scuto-scutellar groove, sometimes inconspicuous (Fig. 3C); scutellum moderately convex, without lateral carinae; sternaulus moderately deep, reaching at least middle of mesopleuron (Fig. 3D); juxtacoxal carina strong, irregular, joining submetapleural carina at anterior 0.3–0.4 (Fig. 3F, arrow); propodeum (Fig. 1B) with strong and conspicuous carinae; area superomedia confluent with area basalis and separated from area petiolaris; inner side of area externa about 3.0– 4.0× as long as inner side of area dentipara; inner side of area dentipara 0.46–0.5× length of outer side; area spiracularis confluent with area lateralis; posterior transverse carina strong, forming a low and wide rounded or slightly subtriangular crest joining lateral longitudinal carina (Fig. 3G, arrow). Length of hind femur 4.0–4.7 × its height. Hind wing with vein cu-a 0.4–0.6 × as long as abscissa of CU between M and cu-a.
METASOMA. Tergite I (Figs 1B, 3B), finely granulate, matt, 1.8–2.0 × as long as its maximum width; postpetiole laterally and posteriorly tending to fine strigosity; lateromedian longitudinal carina weak, reaching at least 0.6 × length of tergite; lateral longitudinal carina weak, complete or absent posterior to spiracles; tergite II (Fig. 3B) smooth and shiny, glabrous; remaining tergites (Fig. 3B) smooth and shiny with inconspicuous dense setiferous punctures. Ovipositor sheath 0.45–0.49 × as long as hind tibia.
COLOUR. Head (Fig. 3A–E) dark brown, clypeus and mandibles reddish brown; palpi light brown; antenna with scape, pedicel and flagellomeres 1–4 light brown, darker dorsally, remaining flagellomeres dark brown, flagellomeres 4–7 dorsally white (Fig. 3A). Mesosoma (Fig. 3A–D) mostly dark orange; mesoscutum with wide dark brown longitudinal bands on central and lateral lobes; dorsal anterior part of propodeum dark brown. Metasoma (Fig. 3B) mostly brown, tergite I sometimes centrally tinged dark brown. Legs (Fig. 3A) light brown, distal tarsomeres dark brown, fore and mid coxae, part of hind coxa and all trochanters and trochantelli lighter. Wings (Fig. 3A) slightly infuscate.
Male
Unknown.
