Krateriske peruensis Huber , sp. n.

( Figs 148 , 152 , 155 )

Type material. Holotype ♀ ( CNC) on card labelled: 1.“ Peru, Huanuco. Rio Llullapichis, 9 º 37 'S 74 º 56 '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, fl 3 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 gt 1, transverse bands on gt 2 –gt 6 (broken medially on gt 6), and legs dark yellow; clava dark brown, scape, pedicel, fl 1 and fl 2 brown; fl 3 light brown, fl 4 –fl 8 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, fl 1 112–129 / 48–59 (2.24–2.33), fl 2 127–150 / 54–62 (2.37–2.44), fl 3 141–154 / 53–64 (2.21–2.67), fl 4 134–163 / 62–70 (2.18–2.46), fl 5 120–129 / 64–76 (1.66–1.88), fl 6 118–127 / 71–78 (1.62–1.73), fl 7 107–112 / 69–74 (1.49–1.71), fl 8 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: fl 1 320, fl 2 371, fl 3 358, fl 4 345, fl 5 345, fl 6 316, fl 7 307, fl 8 256, fl 9 282, fl 10 269, fl 11 307; total flagellar length 3476; fl 6 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.
