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.
