Paratype. 1 female, Japan, “Japan, Yuwan, Amamioshima, 1.V.1959, coll. K. Kamijo, female”,“0000094535 Sys. Ent Hokkaido Univ. Japan” ( EIHU) .

Description. Female. Body length 4.50– 4.60 mm; fore wing length 3.00– 3.10 mm.

Head dark metallic green with diffuse coppery lustre. Antenna with scape and pedicel yellowish-brown, flagellum and clava brown. Mesosoma metallic blue-green with diffuse coppery lustre. Fore and hind coxae metallic green basally and yellowish-brown apically, mid coxa yellowish-brown, femur, tibia and tarsus yellow, last segment of tarsus yellowish-brown. Fore wing hyaline, venation yellowish-brown. Metasoma with Mt2 metallic green, Mt3–Mt8 brown with diffuse coppery or violaceous lustre; ovipositor sheath black.

Sculpture of head dorsally reticulate, clypeus smooth and shining,malar space weakly reticulate. Pronotum, mesoscutum and frenal area reticulate, axilla and scutellum finely reticulate, lateral areas of propodeum weakly reticulate. Metasoma weakly alutaceous or smooth and shining.

Head in dorsal view 2.25–2.40 times as broad as long and 1.33–1.38 times as broad as mesoscutum; in frontal view 1.30 times broader than high. POL 1.10–1.22 times OOL. Eye height 1,27–1.30 times eye length and 2.85–3.10 times as long as malar space. Distance between antennal toruli and lower margin of clypeus 0.72 times distance between antennal toruli and median ocellus. Antenna with scape 0.63–0.70 times as long as eye height and 0.91 times as long as eye length; pedicel 1.45–1.59 times as long as broad and 0.40 times as long as F1; combined length of pedicel and flagellum 1.70–1.80 times breadth of head; flagellum almost filiform; all anelli transverse; F1 2.83–2.85 times as long as broad, with three rows of dense sensilla; F2–F6 longer than broad.

Mesosoma 2.0 times as long as broad. Scutellum 1.20–1.26 times as long as broad. Propodeum medially 0.33–0.35 times as long as scutellum; median carina complete and straight; nucha absent.

Fore wing 2.63–2.75 times as long as maximum width; basal cell pilose apically; speculum closed; costal cell with two complete rows of setae; marginal vein 0.78–0.86 times as long as postmarginal vein and 2.26–2.50 times as long as stigmal vein.

Metasoma lanceolate, 2.20–2.26 times as long as mesosoma and 1.50–1.57 times as long as mesosoma and head; Mt8 2.0–3.0 times longer than its maximum width; ovipositor sheath 0.55–0.70 times length of Mt8.

Male. Unknown.

Comparative diagnosis. This species is similar to J. caudata in having the fore wing hyaline and body length 2.10–4.60 mm. However, J. kawabatai has the basal cell of fore wing pilose apically (vs bare or with three setae), costal cell with two complete rows of setae (vs one complete row), F1 with three rows of dense sensilla (vs two rows), head in dorsal view shallowly emarginate (vs distinctly emarginate). Janssoniella kawabatai is also similar to Holarctic J. intermedia in having the fore wing hyaline, costal cell with two complete rows of setae, F1 with three rows of dense sensilla, and the head in dorsal view shallowly emarginate. However, J. kawabatai has the basal cell pilose apically (vs bare), marginal vein 2.26–2.50 times as long as stigmal vein (vs 1.80–2.0 times), fore and hind coxae metallic green basally and yellowish-brown apically, mid coxa yellowish-brown (vs all coxae with orange tint).

Etymology. The species is named in honour of the famous Japanese writer, Yasunari Kawabata.

Distribution. South Korea, Japan.

Biology. Unknown.
