Description. Female (n = 6). Body length 8.2–8.5 (HT: 8.5) mm, matt and covered with silver setae.
Head 0.65–0.7 (HT: 0.67) × as long as wide in dorsal view. Clypeus 2.7–2.8 (HT: 2.7) × as broad as high, sparsely punctate, lower margin rounded ( Fig. 40E View Fig ), thick in lateral view. Face 2.0 × as broad as high, flat, densely punctate. Dorsal profile of gena as Fig. 38E View Fig . Occipital carina complete. Length of malar space 0.85– 1.0 (HT: 0.9) × as long as basal width of mandible. Base of mandible flat. POL 0.7–0.75 (HT: 0.75) × as long as OD. OOL 1.5–1.8 (HT: 1.5) × as long as OD. Antenna with 48–49 (HT: 49) flagellomeres. FL I 5.7– 6.65 (HT: 5.7) × as long as maximum depth, 1.55–1.65 (HT: 1.6) × as long as FL II.
Mesosoma largely pustulate. Epomia absent. Mesoscutum with weak notaulus. Epicnemial carina present laterally and ventrally. Speculum with a small smooth area ( Fig. 9C View Fig ). Mesopleuron with oblique rugae in front of speculum ( Fig. 9C View Fig ). Propodeum with all carinae except for anterior transverse carina. Lateromedian longitudinal carina and lateral longitudinal carina obscured anteriorly ( Fig. 9D View Fig ). Fore wing length 7.0–7.7 (HT: 7.7) mm. Areolet present, shortly petiolated, received vein 2m-cu slightly based of the outer angle ( Fig. 9E View Fig ). Fore wing vein 1cu-a interstitial to vein M&RS. Nervellus subvertical, intercepted slightly anterior the middle. Tarsal claws pectinate. Hind femur 5.1–5.4 (HT: 5.4) × as long as maximum depth in lateral view. Ratio of length of hind first to fifth tarsomeres 4.0–4.2 (HT: 4.2): 2.0: 1.5: 0.9: 1.0.
Metasoma. T I 2.0–2.2 (HT: 2.0) × as long as maximum width. T II 0.75–0.85 (HT: 0.75) × as long as maximum width. Ovipositor sheath 0.175 × as long as hind tibia.
Colouration ( Figs. 9A–E View Fig ). Body (excluding wings and legs) black. Antenna with a white band. A median reverse T-shaped spot of face, clypeus, ventral surfaces of scape and pedicel, and flagellum except for a white band reddish yellow to reddish brown. Mandible except for teeth, palpi, tegula, and membranous part of metasomal sternites yellow to yellowish brown. Posterior margin of T I, T II to T IV reddish brown to red. T V to T VII and ovipositor sheath more or less tinged with reddish brown. T I sometimes entirely black. T II sometimes with a black area. Wings hyaline. Veins and pterostigma brown to yellowish brown except for yellow wing base. Coxae black. Trochanters black with whitish yellow area(s). Trochantelli whitish yellow. Femora, tibiae, tibial spurs, and tarsi brown to brownish yellow except for hind femur blackish brown to black. Fore and mid femora and apical part of hind tibia more or less darkened. Hind TS III and TS IV usually tinged with whitish yellow.
Male (n = 9). Similar to female. Body length usually slightly shorter than female (minimum specimen: 7.5 mm). Length of malar space 0.7–0.8 × as long as basal width of mandible. POL 0.6–0.7 × as long as OD. OOL 1.4 × as long as OD. Antenna with 45–49 flagellomeres. Hind femur 4.8–5.0 × as long as maximum depth in lateral view. T I 2.5 × as long as maximum width. T II 0.95–1.0 × as long as maximum width. A pair of longitudinal markings of frontal orbit, face, malar space, clypeus, mandible except for teeth, ventral surface of scape, and a pair of triangle markings of antero-lateral corner of mesoscutum yellow ( Figs. 9 F, G View Fig ). Fore and mid coxae largely yellow ( Fig. 9F View Fig ). T II usually largely black.
Distribution. Japan (Honshu).
Bionomics. Unknown.
Etymology. The specific name is from the Latin “ flavi -” (yellow) plus “ dens ” (mandible), which means yellow mandible.
Remarks. This species resembles E. nemoralis (Geoffroy, 1785) in body structure and colouration (e.g., antenna with white band), but can be distinguished by the whitish yellow hind trochantellus (blackish brown in E. nemoralis ), the speculum with a small smooth area (rather large smooth area in E. nemoralis ), the mesopleuron with oblique rugae anterior to the speculum (without conspicuous rugae in E. nemoralis ), the whitish yellow female tegula (blackish brown in female of E. nemoralis ), and the yellow face of male (black in male of E. nemoralis ). In Japanese species, this species is similar to E. japonicus , but can be easily distinguished by the flat base of the mandible (convex in E. japonicus ).
