Material examined: Good quality images of the Holotype of Grotea perplexa (Canadian National Collection of Insects-CNC).

Description. Female.

Head. Head in dorsal view with gena behind eyes slightly concave ( Figs 22 & 23 ); postgenal process present, laterally distinct (gena with ventroposterior angle modified to form an inconspicuous tooth that is horizontally oriented to inside of the oral cavity, and with apex quadrate) ( Fig. 19 ). Flagellomere I 1.07× as long as flagellomeres II and III combined. Clypeus pentagonal ( Fig. 24 ).

Mesosoma. Mesoscutum smooth with setiferous punctures that are more concentrated on the sides ( Figs 20 , 22 & 24 ); scutellum in profile convex; propodeum with area basalis elongate, but not fully defined by carinae, about 2.0× as long as broad; anterior transverse carina forming a smooth arc; lateral longitudinal carina distinct only in the posterior margin (anteriorly absent); area spiracularis enclosed, posteriorly and laterally, though mesally not separated from area externa; pleural carina present; posterior transverse carina, centrally absent; area lateralis rectangular and enclosed, about 2.0× as long as broad, with posterolateral corner at right angle close to lobe surrounding coxal insertion ( Fig. 22 ). Mesosoma 1.05× as long as tergite I ( Fig. 19 ). Fore wing 11.0 mm long, hind wing 7.03 mm.

Metasoma. Metasoma with tergite I slender, slightly shorter than mesosoma from pronotal collar to posterior margin of propodeum ( Fig. 19 ). Visible part of the ovipositor 1.97× as long as posterior tibia.

Coloration (Modified from Slobodchikoff, 1970) ( Figs 19–24 ).

Head white, suffused with brown about ocelli and behind eyes; antennal flagellum black. Pronotum orange, white on anterior 0.1 and yellow along dorsoposterior margins; mesopleuron orange with yellow spot along anterodorsal margin; mesoscutum orange; metapleuron white; scutellum and postscutellum yellow; propodeum mostly orange, apical 0.1 white. Fore leg mostly white: femur with orange band on median 0.7 of posterior face. Mid coxa white; trochanter brown on anterior face, white on posterior; trochantellus white; anterior face of mid femora white, posterior face white on distal 0.6, orange on proximal 0.4; mid tibia white, suffused with orange along inner faces; middle tarsi brownish grey, white on distal 0.2. Anterior face of hind coxa white, with orange band on median 0.3; posterior face orange on proximal 0.7 and white on distal 0.3; trochanter orange, white on distal 0.4; trochantellus white; hind femur orange, white on distal 0.2; hind tibia grey, white on distal 0.2; hind tarsus brownish grey, white on distal 0.2. First tergite orange. Metasomal sternites white; metasomal tergites brown-black, tergites 2–6 each with median cuneate white spot near posterior margin. Distal tip of fore wing lacking conspicuous brown spot.

Distribution: Brazil: Santa Catarina: Nova Teutonia.
