Krateriske ecuadorensis Huber , sp. n.

( Figs 150 , 153 )

Type material. Holotype ♀ ( CNC) on card labelled: 1.“ Ecuador: Napo, Yasuni Biol. Res. Station, 220m, 0.67ºS 76.39ºW, PT, 18–26.v.1996, P. Hibbs”. 2. “ Holotype Krateriske ecuadorensis Huber ♀.”

Paratypes. 2 ♀ and 1 ♂ on points or cards, 1 pair of wings and one ♀ antenna on slide. ECUADOR. Napo. Same data as holotype (1 ♀, CNC); 21 km E. Puerto Napo, Jatun Sacha Biological Station, 400m, 15.vii.1994, Levy & Génier, FIT, virgin rain forest (1 ♀, CNC); Lumbaqui, 10.iii.1983, L. Huggert (1 ♂, CNC).

Diagnosis. Krateriske ecuadorensis differs from K. guianensis by the fore wing ( Fig. 153 ) with a light transverse median band separating darker proximal and apical areas. It differs from K. peruensis by the fore wing with narrower transverse median and apical white bands, the hind wing wider just beyond venation, the female antenna with fl3 brown ( Fig. 150 ), and propodeum with median raised oval wider.

Description. FEMALE. Body length 2355–2430 (n=3). Colour. Head, radicle except narrowly near apex, mesosoma, petiole, and legs brownish yellow, with face dorsally, coxae and trochanters lighter yellow; radicle narrowly near apex, fl1–fl3 (fl3 becoming lighter apically), and pretarsus dark brown, fl4–fl8 white; gaster with terga dorsally except gt6 each with a narrow brown band separated from each other by white intersegmental membrane, gt6 with band broken into two sublateral brown spots. Fore wing ( Fig. 153 ) with a light transverse median band and apical spot between darker areas; hind wing slightly darker basally and apically and lighter medially beyond venation. Head. Head width 630–640 (n=3, card mounts). Antenna. Each funicle segment with 2 mps, except 1 (possibly 2) on fl1. Antennal measurements (n=1) length/width (ratios of funicle segments): scape 793/110, pedicel 107/64, fl1 133/60 (2.21), fl2 158/59 (2.66), fl3 161/60 (2.68), fl4 147/61 (2.42), fl5 126/69 (1.83), remaining segments missing. Mesosoma. Propodeum with median oval slightly wider dorsally than ventrally and blunt, with a few short carinae extending outwards from oval. Wings. Fore wing length (n=1) 2642, width 630, length/width 4.19, longest marginal setae 85. Hind wing length 2075, width 134, longest marginal setae 145. Metasoma. Ovipositor sheath length 538, distinctly shorter than metatibial length (998) (point mounted specimen).

MALE. Body length 2150 (n=1). Colour. Head, mesosoma and antenna (except apical two flagellomeres white) dark brown with H-shaped yellowish sublateral streak on mesoscutum and scutellum (specimen may be slightly teneral) and sublateral streak on mesosternum between pro- and mesocoxae; fore wing with wider light transverse band than in female and apex not distinctly lighter. Antenna. Dark brown, pedicel brown, apical two flagellar segments yellow. Measurements (n=1, card mount): scape length/width 218/89, pedicel length/width 59/ 79, flagellar segment length: fl1 366, fl2 366, fl3 376, fl4 376, fl5 376, fl6 347, fl7 347, fl8 257, fl9 307, fl10 287, fl11 367; total flagellar length 3775; fl6 length/width 4.4, with about 16 mps. Metasoma. Genitalia not examined (slide of unique male not prepared).

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