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 gt 6 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), gt 6 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 fl 1 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, fl 1 106–110 / 50–54 (2.04–2.11), fl 2 118–119 / 53–55 (2.13–2.66), fl 3 116–120 / 53–57 (2.04–2.27), fl 4 116–117 / 59–64 (1.81–1.97), fl 5 106–110 / 58–67 (1.57–1.90), fl 6 96–99 / 66 (1.46–1.51), fl 7 86–91 / 66–67 (1.28–1.39), fl 8 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 gt 6, 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: fl 1 276, fl 2 335, fl 3 328, fl 4 338, fl 5 342, fl 6 323, fl 7 290, fl 8 263, fl 9 267, fl 10 281, fl 11 306; total flagellar length 3351; fl 6 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.
