Krateriske peruensis Huber , sp. n.

( 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.
