Labium, clypeus, mandibles, triangular supraclypeal area and 1-1 rounded spot around scapes white. Scape black. Pedicell and antennái flagellar segments black above and ferrugineous below. Thorax black, only tegulae and wide hind corner of the pronotum white. Legs entirely white from the coxae till the trochanters. Wings hyaline. Stigma costa and venation brown. Basal fifth of costa white. Abdominal tergites dominantly black. Last abdominal tergite entirely, all sternites and lateral part of the tergites white. Basal half of ovipositor white, apical half black. Clypeus roundly emarginated in the middle. Depth of clypeal emargination about 0.4x as deep as the clypeal median length. Vertex and temples without hind postoccipital carina. Ratios of the antennái segments: 5 : 3 : 21 : 21 : 20 : 17 : 15 : 15 : 15. OOL : POL : OCL = 7:9: 10. Longest diameter of an eye : length of the 3rd antennái segment = 20 : 21 (subequal). Inner margines of the eyes paralell. Frontal area not marked. Head densely and irregularly punctured, shiny. Fore lobes of mesonotum with sparse punctures, between the punctures with irregular fine surface sculpture. Moderately shiny. Lateral lobes of mesonotum unpunctured, with fine surface sculpture, moderately shiny. Mesoscuttellum with sporadic irregular punctures, moderately shiny. Mesoscutellar appendage with few longitudinal wrinkles in the middle and with very fine suface sculpture, moderately shiny. Mesopleuron with very fine, shallow, small and uniform punctures, moderately shiny. Sawsheath about as long as the cerci, narrowed and subacute (Fig. 9). Sawsheath as long as the 2 basal segments of hind tarsus (1.0 : 1.0). Length: 5.5 mm, length of fore wing: 5.7 mm. Holotype: female: Kuril Islands, Kunasir Island, Tretjakovo, 04. 08. 1973. Nematus {Pteronidea) kunasirensis spec. nov. Female. Head black. Narrow inner orbit up to the upper corner of eyes together with the major part of the temples and triangular supraclypeal area ferrugineous. Labrum, wide front margin of clypeus and mandibles white. Scape and pedicell black. Antennái flagellar segments black above and ferrugineous below. Thorax black, tegulae, wide hind corner of the pronotum and postnotum next to the cenchri and around the postscutellum white. Legs entirely white from the coxae till the trochanters. Wing hyaline, venation brown. Costa and stigma transparent yellow. Abdomen yellowish white (possibly green in the living animal). Abdominal tergites in the middle with brownish black bands. Last abdominal tergite entirely yellowish white. Ovipositor white, only its narrow apical margin brown. Ratios of the antennái segments: 4 : 2 : 14 : 15 : 15 : 12 : 11 : 10 : 10. OOL : POL : OCL = 1.0 : 1.0 : 1.0. Length of 3rd antennái segment : longest axis of eye = 29 : 28. Frontal pentagonal area sunken. Vertex and temples without hind occipital carina. Clypeus roundly emarginated in the middle. Depth of clypeal emargination about 0.4x as deep as the clypeal median length. Inner margines of eyes paralell. Genae about as long as the diameter of the front ocellus. Head unpunctured but with very fine surface sculpture, shiny. Mesonotum, mesoscutellum, mesoscutellar appendage unpunctured, with fine coriaceous surface sculpture, shiny. Postscutellum smooth and shiny. Mesopleuron with minute, shallow punctures, shiny. Sawsheath bluntly rounded in dorsal view (Fig. 10). Ovipositor as long as the 2 basal segments of hind tarsus: 1.0 : 1.0. Length of hind basitarsus : length of inner hind tibial spur = 5:3. Length: 7.4 mm, length of fore wing: 6.6 mm. Holotype: female: Kuril Islands, Kunasir Island, Tretjakovo, 07. 08. 1973.
