Face 2.1-2.4 (HT: 2.4) × as broad as high, densely punctate, convex medially in lateral view and separated from clypeus by shallow clypeal sulcus. Inner orbits almost parallel (Fig. 1B View Figure 1 ). Length of malar space 0.9-1.15 (HT: 0.9) × as long as basal mandibular width. POL 1.9-2.1 (HT: 1.9) × as long as OD. OOL 0.9-1.18 (HT: 0.9) × as long as OD. POL 1.86-1.95 (HT: 1.86) × as long as OOL. Antenna with 24-25 (HT: 24) flagellomeres. FL I 1.29-1.35 (HT: 1.35) × as long as FL II. MP IV1.42-1.53 (HT: 1.53) × as long as MP V.
Mesosoma. Lateral aspect of pronotum strigose anteriorly. Mesoscutum finely and densely punctate (separated by ca.1.0 × their diameter) (Fig. 1C View Figure 1 ). Scutellum finely and sparsely punctate (separated by ca.1.5-2.5 × their diameter) (Fig. 1C View Figure 1 ). Anterior part and lower half of mesopleuron coarsely and densely punctate. Speculum smooth. Sternaulus weakly impressed. Propodeum finely rugulose (Fig. 1D View Figure 1 ), rounded in lateral view and pleural carina entirely present. Fore wing length 7.4-8.5 (HT: 7.4) mm. Nervellus intercepted below middle. Hind femur 4.7-5.3 (HT: 4.7) × as long as maximum depth in lateral view. Hind tibia 7.5-8.0 (HT: 8.0) × as long as maximum depth in lateral view. Ratio of length of hind first to fifth tarsomeres 1.0: 0.6: 0.4: 0.2: 0.2-0.3 (HT: 0.2).
Metasoma. T I rectangular in dorsal view (Fig. 9E View Figure 9 ), 1.4-1.5 (HT: 1.4) × as long as maximum width, irregular rugulose laterally, sometimes striate between latero-median carinae. Latero-median carina present basal ca. 0.5 of T I (Fig. 9E View Figure 9 ). T II 0.6-0.73 (HT: 0.73) × as long as maximum width, striate anteriorly and strigose laterally.
Coloration (Fig. 1A-D View Figure 1 ). Body (excluding wings and legs) black. Face with a large yellow spot medially. Palpi, subtegular ridge and mesepisternum yellow. Mandible yellow, except for apex and base. Lateral aspect of pronotum with a yellow spot posteriorly. Mesoscutum with yellow shoulder marks. Tegula tinged with yellow anteriorly. Scutellum with a yellow spot apically. Wings hyaline. Veins and pterostigma blackish-brown except for yellowish-brown wing base. Legs blackish-brown to black. Fore trochanter, trochantellus, apex of hind femur and base of hind tibia tinged with white. Fore femur, tibia and tarsomeres orange to brown. Apex of hind trochantellus and base of hind femur tinged with reddish-brown.
Male (n = 1). Similar to female. Body length (excluding antennae) 8.1 mm. Face 2.5 × as broad as high. Length of malar space 0.8 × as long as basal mandibular width. POL 2.2 × as long as OD.

Coloration (Fig. 1E, F View Figure 1 ). Body (excluding wings and legs) black. Clypeus, palpi, face, ventral surface of antenna, malar space, propleuron, epicnemium, mesosternum, tegula, subtegular ridge and mesepisternum yellow. Gena tinged with yellow ventrally. Mandible yellow, except for apex. Lateral aspect of pronotum tinged with yellow ventrally and posteriorly. Mesopleuron with a large yellow marking, it enlarged anteriorly. Scutellum with a yellow spot apically. T IV to T VII with a transverse yellow band posteriorly. Wings hyaline. Veins and pterostigma brown to blackish-brown except for yellow wing base. Legs yellow to yellowish-brown. Hind coxa and trochanter each with a blackish-brown stripe dorsally. Hind trochantellus and tibia tinged with blackish-brown.
Distribution.
Japan (Honshu).
Bionomics.
Host unknown. Adults were collected in broad-leaved forest at altitudes of ca. 1,000-2,000 meters.
Etymology.
The species name refers that this species inhabits alpine region.
Remarks.
This species resembles W. kuroashii but can be distinguished from the latter by the following combination of character states: pleural carina of propodeum entirely present in both sexes (absent posteriorly in both sexes of W. kuroashii ); propodeum finely rugulose in both sexes (coriaceous in both sexes of W. kuroashii ); T I 1.4-1.5 × as long as maximum width in both sexes (1.1-1.25 in females, 1.14-1.26 in males of W. kuroashii ). This species also resembles a Korean species, W. pallidus Balueva & Lee, 2016 (male is unknown), but can be distinguished by the following combination of character states in females: a large yellow median spot of face present (absent in W. pallidus ); antenna with 24-25 flagellomeres (22-23 in W. pallidus ); scutellum finely and sparsely punctate on coriaceous background (entirely coriaceous in W. pallidus ); propodeum finely rugulose (coriaceous in W. pallidus ).
