Kiwi oreteus Khalaim & Ward

sp. nov.

Kiwi oreteus Khalaim & Ward  , sp. nov.

( Figs 12View FIGURES 11–14, 33–37View FIGURES 33–37, 62)

Comparison. The new species is similar to K. ruzelus but differs from it by the shape of the ovipositor ( Fig. 36View FIGURES 33–37), weaker foveate groove of mesopleuron ( Fig. 35View FIGURES 33–37), first tergite less slender and evenly arcuate in lateral view ( Fig. 37View FIGURES 33–37), and shorter second tergite.

Description. Female. Body length 2.7 mm. Fore wing length 2.0 mm Head in dorsal view strongly roundly tapered behind eyes, with gena about 0.55× as long as eye width ( Fig. 34View FIGURES 33–37). Head without distinct punctures; clypeus smooth, sometimes slightly scabrous near upper margin; face and frons granulate, dull; vertex and gena shallowly granulate, weakly shining. Clypeus lenticular, weakly convex. Flagellum slightly clavate, basally slender, with 16–17 flagellomeres (16 in holotype); flagellomeres 2 and 3 almost 2.5× and subapical flagellomeres 1.4–1.6× as long as broad ( Fig. 33View FIGURES 33–37). Mandible slender, with upper tooth somewhat longer than the lower. Malar space 0.8–1.0× as long as basal mandibular width.


Mesosoma entirely granulate, impunctate, dull. Notaulus with a strong longitudinal wrinkle on anterolateral side of mesoscutum. Foveate groove thin to moderately broad, almost horizontal, extending in front 0.5–0.7 of mesopleuron, sometimes with weak transverse wrinkles ( Fig. 35View FIGURES 33–37). Propodeal spiracle separated from pleural carina by half diameter of spiracle. Propodeum with basal part about as long as apical area; transverse carina well developed; apical area widely rounded or obtusely pointed anteriorly; apical longitudinal carinae complete. Fore wing with vein 2m-cu interstitial or slightly postfurcal, unpigmented anteriorly, with posterior end distinct.

First tergite about 3.4× as long as posteriorly broad, in lateral view with upper margin evenly arcuate ( Fig. 37View FIGURES 33–37); petiole longitudinally striate, postpetiole granulate. Glymma deep, situated approximately in centre of tergite, joining by distinct furrow to ventral part of postpetiole ( Fig. 37View FIGURES 33–37). Second tergite as long as anteriorly broad. Thyridial depression transverse. Ovipositor short, relatively robust, weakly upcurved, with shallow dorsal subapical depression and a slight rounded swelling before this depression ( Fig. 36View FIGURES 33–37); sheath 0.8–0.9× as long as hind tibia.

Body reddish orange to brown ( Fig. 12View FIGURES 11–14), darker paratypes have head, mesosoma and first tergite dark reddish brown to blackish. Clypeus (except extreme upper margin), mouthparts, mandible (teeth red) and tegula yellow. Legs yellow; hind coxa darkened with brown, and sometimes hind femur, tibia and tarsus also infuscate. Scape and pedicel yellow to brownish yellow; flagellum brown, pale basally. Pterostigma pale brown.

Male. Unknown.
