(Figs 148, 152, 155)

Type material. Holotype ♀ (CNC) on card labelled: 1.“ Peru, Huanuco. Rio Llullapichis, 9º37'S 74º56'W, 260m, 1.xi.1981, M.V. Tshirnaus, YPT, primary forest”. 2.” Holotype Krateriske peruensis Huber ♀”.

Paratypes. 7 ♀, 2 ♂. PERU. Huanuco. Same data as holotype (7 ♀, 2 ♂, CNC).

Diagnosis. Krateriske peruensis differs from K. guianensis by the fore wing with transverse white bands (Fig. 155) and from K. ecuadorensis by the fore and hind wing white bands wider, the hind wing narrower just beyond the venation, fl3 white (Fig. 152), and propodeum with median raised oval narrower.

Description. FEMALE. Body length 2100–2300 (n=4). Colour. Radicle, head, mesosoma, a longitudinal band on gt1, transverse bands on gt2–gt6 (broken medially on gt6), and legs dark yellow; clava dark brown, scape, pedicel, fl1 and fl2 brown; fl3 light brown, fl4–fl8 white. Fore wing (Fig. 155) with a light apical spot, and light transverse median band between darker areas; hind wing slightly darker basally and apically and lighter medially beyond venation. Head. Head (Fig. 148) width 649–696 (n=2). Antenna. Each funicle segment with 2 mps (Fig. 152). Antennal measurements (n=3) length/width (ratios of funicle segments): scape 774–837/114–122, pedicel 108–115/66–69, fl1 112–129/48–59 (2.24–2.33), fl2 127–150/54–62 (2.37–2.44), fl3 141–154/53–64 (2.21–2.67), fl4 134–163/62–70 (2.18–2.46), fl5 120–129/64–76 (1.66–1.88), fl6 118–127/71–78 (1.62–1.73), fl7 107–112/69–74 (1.49–1.71), fl8 84–102/70–74 (1.19–1.39), clava 713–757/121–140. Mesosoma. Propodeum with median oval slightly narrower dorsally than ventrally and slightly pointed, with carinae extending outwards from oval very short or absent. Wings. Fore wing length 2676–2836 (n=3) width 634–665, length/width 4.14–4.47, longest marginal setae 98–109. Hind wing length 2013–2217, width 142 (n=1), longest marginal setae 122–143. Metasoma. Ovipositor sheath length 662–709 (n=2), distinctly shorter than metatibial length (937–982).

MALE. Body length 2400–2500 (n=2). Colour. Mesosoma brown, otherwise as in female but flagellum dark brown except apical 2 or 3 segments yellowish white. Antenna. Measurements (n=1, card mount): scape length/ width 170/79, pedicel length/width 79/69, flagellar segment length: fl1 320, fl2 371, fl3 358, fl4 345, fl5 345, fl6 316, fl7 307, fl8 256, fl9 282, fl10 269, fl11 307; total flagellar length 3476; fl6 length/width 4.0, with about 14 mps in each of 3 irregular whorls. Metasoma. Genitalia not examined (slides of males not prepared).

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