(Figs 1 B–E, 3G–I, 5C)
Xiphydria kastsheevi: Hara & Shinohara, 2018: 108. Not Ermolenko, 1979.
Description. Female (holotype, Figs 1D, 3G–I, 5C). Length without ovipositor about 10.0 mm. Head black, with clypeus, supraclypeal area, lower inner orbit, malar space, lower part of gena, spot on lateral posterior part of vertex, and paired spots in anterior part of vertex dirty yellowish white. Mouth parts pale brown; ligula mostly whitish and mandible dirty yellowish white except for blackish apex. Antenna blackish brown to black. Thorax black, with ventral posterior part of lateral pronotum, narrow dorsal posterior corner of pronotum and posterior part of tegula dirty yellowish white. Legs blackish brown; bases of all tibiae (broadly in mid and hind legs) and most of tarsomeres (apically dark) whitish. Wings strongly stained with black, with apical 1/3 becoming hyaline; veins and stigma blackish brown. Abdomen black, with small lateral spots on terga 2–5, broad lateral part of tergum 8, and broad lateral posterior margin of tergum 9 creamy white; ovipositor sheath with very narrow apex pale brown.
Malar space about 0.3× length of distance between toruli, with ventral pit deep and sharply delimited; occipital carina (crassa) distinct, entire; genal carina developed nearly to vertex but their dorsal ends widely separated from each other; inner orbits subparallel, interocular distance at level of toruli about 1.2× eye height. Labial palpus with 3 palpomeres; maxillary palpus with 5 palpomeres. Both antenna with 16 antennomeres; scape (incl. radicula):pedicel:flagellomere 1:flagellomere 2 as 2.1:1.0:1.5:0.9. Hind tarsomere 1 about 0.7× length of remaining tarsomeres combined; tarsal claws with large inner tooth. Forewing with cell 3R1 closed at apex (vein R1 connecting with vein Rs); crossvein 2r-rs missing; cell 2Rs about as wide as cell 1M; crossvein 2r-m basal to crossvein 2m-cu on vein M (Fig. 1D); hindwing with cell R1 closed and rounded at apex posteriorly (Fig. 1D). Abdominal tergum 10 normal, not directed dorsally at apex in lateral view (Fig. 5C). Ovipositor sheath with apical sheath subequal in length to basal sheath.
Frons and interantennal area roughly reticulate; rather even, coriaceous space from median ocellus to median fovea; gena roughly shallowly rugose, with some large ill-defined punctures; pale area of lateral clypeus to lower inner orbit very shallowly finely striate and coriaceous, without distinct punctures (Fig. 3 G–I). Pronotum irregularly wrinkled in dorsal half, smooth with several longitudinal ridges at middle, and very smooth and impunctate in ventral half; propleuron roughly shallowly wrinkled but without distinct punctures and surface rather smooth; mesoscutal median lobe coarsely reticulate; lateral lobes reticulate with large elongate patch coriaceous, mat and impunctate; mesoscutellum densely rugoso-reticulate, posterolateral part densely punctate; mesepisternum rugosoreticulate, pilose; mesepimeron nearly impunctate and glabrous, coarsely and obliquely wrinkled; metepisternum and metepimeron coarsely rugoso-reticulate. Abdomen with tergum 1 coarsely punctate, each half with broad inner margin nearly impunctate and shining; all other terga weakly shining with very fine surface microsculpture.
Male. Unknown.
Variation. The length without ovipositor varies from 8.0 to 10.0 mm. The pale spots on the vertex and gena are reduced in two paratypes. The paratype from Take has paler legs, with the apical parts of the femora whitish. The six antennae examined have 15–17 antennomeres. Crossvein 2r-rs is absent in the paratype from Bibai (Fig. 1B) as in the holotype (Fig. 1D), but the crossvein is present in the other paratype from Take. The apical sheath is about 1.0–1.1 × as long as the basal sheath.
Type material examined. Holotype: ♀, Hitsujigaoka, Sapporo, Hokkaido, Malaise trap, 27. VIII.–3. IX. 2003, K. Konishi (NSMT). Paratypes: HOKKAIDO: 1♀, Bibai, Koshunai, 13. IX. 2013, H. Hara (NSMT). HONSHU:
Iwate Pref.: 1♀, Take, foot of Mt. Hayachine, 8. VII. 1967, R. Ishikawa (NSMT).
Distribution. Japan (Hokkaido, Honshu).
Host plant. Unknown.
Etymology. This new species is named in honor of Dr. Kazuhiko Konishi, Ehime University, Matsuyama, who collected the holotype.
Remarks. Hara & Shinohara (2018) recorded this species under the name of X. kastsheevi based on the three specimens listed above. However, further study has indicated that the three Japanese specimens differ from X. kastsheevi and represent a new species, X. konishii. It has the clypeus and supraclypeal area entirely dirty yellowish white (Fig. 3H, I) and abdominal terga 2 and 3 pale-marked laterally, whereas X. kastsheevi has the median part of the clypeus, the entire supraclypeal area and the entire abdominal terga 2 and 3 black (Ermolenko 1979). Xiphydria konishii is also very close to another new species described below, X. melanoptera, but in addition to the pale clypeus and supraclypeal area and presence of pale lateral spots on abdominal terga 2 and 3, the smaller number of antennomeres (15–17) and normal shape of abdominal tergum 10 (Fig. 5C) will distinguish X. konishii.
