Diagnosis. Krateriske guianensis is distinguished from the other two Krateriske species by the fore wing with a light longitudinal band between a darker anterior and posterior areas ( Figs 146 , 154 ).

Description. FEMALE. Body length 2125–2300 (n=8). Colour. Mesosoma, petiole, legs and antenna except clava brownish yellow, sometimes with pronotum, lateral lobe of mesoscutum, and anterior scutellum lighter; head light brown, clava and pretarsus dark brown, gaster with terga dorsally except gt6 each with a narrow brown band slightly wider laterally and sometimes also medially, the bands well separated from each other by white intersegmental membrane ( Figs 156, 158 ), gt6 with band broken into two sublateral brown spots. Fore wing ( Fig. 154 ) with a light longitudinal band between darker anterior and posterior areas; hind wing darker in apical half beyond venation. Head. Head ( Fig. 147 ) width 662–683 (n=2). Antenna. Each funicle segment with 2 mps except fl1 without mps, and clava with about 35 mps ( Fig. 151 ). Antennal measurements (n=2), length/width (ratios of funicle segments): scape 722–744/108–115, pedicel 105–106/62–64, fl1 106–110/50–54 (2.04–2.11), fl2 118–119/ 53–55 (2.13–2.66), fl3 116–120/53–57 (2.04–2.27), fl4 116–117/59–64 (1.81–1.97), fl5 106–110/58–67 (1.57–1.90), fl6 96–99/66 (1.46–1.51), fl7 86–91/66–67 (1.28–1.39), fl8 77–80/67–70 (1.09–1.19), clava 633–661/106. Mesosoma. Propodeum with median oval slightly wider dorsally than ventrally and blunt, with carinae extending outwards from oval quite long ( Figs 159 , 169–172 ). Wings. Fore wing length (n=2) 2522–2550, width 610–638, length/width, 4.00–4.14, longest marginal setae 88–90. Hind wing length 2050–2112, width 115–132, longest marginal setae 114–116. Metasoma. Ovipositor sheath length 595 (n=1), distinctly shorter than metatibia length (~ 860).

MALE. Body length 2225–2500 (n=6). Colour. Gaster ( Fig. 160 ) with wider brown bands and larger spots on gt6, with relatively less white intersegmental membrane visible than in female; flagellum dark brown. Antenna. Measurements (n=1): scape length/width 171/86, pedicel length/width 78–75, flagellar segment length: fl1 276, fl2 335, fl3 328, fl4 338, fl5 342, fl6 323, fl7 290, fl8 263, fl9 267, fl10 281, fl11 306; total flagellar length 3351; fl6 length/ width 3.39, with about 16 mps in each of 3 irregular whorls ( Fig. 149 ). Metasoma. Genitalia as in generic description ( Figs 161, 162 ).

Etymology. The species is an adjective named after the country where all the specimens were collected.
