Vanhornia hikosanensis Abe, Yamagishi et Konishi , sp. nov. ( Figs. 3A–F View FIGURE 3 )

Diagnosis. Frontal transverse carina absent; apical margin of labrum weakly convex. Scutoscutellar sulcus with five foveae; mesodiscrimen with 10 strong foveae; median longitudinal carina on dorsal part of propodeum absent, smooth area on postero-lateral part of propodeum absent. Syntergite with longitudinal ridges, reaching to a maximum of 0.4 the length of syntergite, touching first thyridium; antero-dorsal margin of syntergite concave.

Description. Female. Body length 3.8 mm. Color. Body black; antenna, coxae, trochanters, femora, and tibiae brown; tarsi and ovipositor reddish brown.

Antenna. Scape widened apically, 1.5 times as long as width its anterior margin, 3.5 times as long as pedicel; length to width ratio of F9–11: 1.5: 1; 1.6: 1; 2.6: 1.

Head. Head punctate, setose, 1.2 times as wide as its medium length and 1.2 times as wide as mesoscutum in dorsal; face 1.1 times as long as inner distance of eyes; upper part of gena 1.2 times as long as width of eye laterally; eyes oval, narrowed ventrally; POL: OOL=2.1: 1; frontal transverse carina absent; frons bulged dorsally; diameter of antennal socket 0.12 times as long as inner distance of eyes; area between antennal sockets weakly rugose; antennal scrobe present; epistomal sulcus distinct; apical margin of clypeus weakly concave, 0.3 times as wide as inner distance of eyes; malar space very short; median longitudinal sulcus on postero-dorsal part of vertex and antero-dorsal part of occiput weak. Mandible with four distinct teeth; apical margin of labrum weakly convex.

Mesosoma. Pronotum weakly punctate; pronotal scrobe and pronotal collar rugose; dorsal margin of pronotal shoulder developed; epomia present. Anterior margin of mesopleuron rugose, ventral 1/3 of mesopleuron with setae and weakly punctate; mesopleural furrow smooth, its anterior part punctate; mesopleural carina (anterior ridge of mesopleuron) extending to postpectal carina; mesepimeral sulcus foveolate incompletely, its postero-ventral 1/5 smooth; mesodiscrimen with 10 strong foveae; mesoscutum 1.4 times as wide as long, anterior margin foveolate; notaulus foveolate, with seven foveae; parapsidial sulcus weak; scutoscutellar sulcus with five foveae; scutellum smooth, its posterior margin with some foveae; postscutellum strongly foveolate, with median longitudinal carina. Metapleuron areolate-rugose, its anterior margin strongly foveolate; metapleural smooth area present, anterior margin of the area punctate; metapleural carina present; propodeum areolate; median longitudinal carina on dorsal part of propodeum absent, transverse carina present; smooth area on postero-lateral part of propodeum absent.

Wings. Fore wing 2.7 mm long. Vein Rs+M not connected to Cu; radial cell 4.0 times as long as wide; R (costal vein of radial cell) 1.5 times as long as width of stigma; 1cu-a interstitial to M; hind wing with two hamuli on anteroapical margin.

Metasoma. Syntergite 2.0 times as long as maximum width, some longitudinal ridges reaching 0.4 the length of syntergite, touching first thyridium; antero-dorsal margin of syntergite concave; tergite 6 punctate, its antero-dorsal margin smooth, dorso-lateral margin finely punctate; ovipositor reaching around anterior margin of mesodiscrimen.

Male. Unknown.

Holotype. Female. JAPAN: Kyushu, Fukuoka Pref., Tagawa-gun, Soeda-cho , Mt. Hiko , 33.482N 130.908E, alt. 650 m, MT, 28 V–20 VI 2022, Junta Abe leg. ( ELKU). GoogleMaps

Host. Unknown.

Distribution. Japan.

Etymology. The specific epithet is derived from the type locality, “Hiko-san” called in Japanese.

Remarks. This new species is closely related to V. eucnemidarum in having following characteristics: frontal transverse carina absent; scutoscutellar sulcus with five foveae; mesodiscrimen with about 10 foveae; ridges on syntergite touching first thyridium. However, it can be distinguished by following characteristics: apical margin of clypeus weakly convex (straight in V. eucnemidarum ); median longitudinal carina on dorsal part of propodeum absent (present in V. eucnemidarum ); smooth area on postero-lateral part of propodeum absent (present in V. eucnemidarum ); antero-dorsal margin of syntergite strongly concave (almost straight in V. eucnemidarum ).
