 Perispuda bibullata Sheng, 1999 in Sheng et al. (1999): 5.   
 Description based on Japanese specimens. Female (n = 8). Body length 15.0–17.0 mm, covered with punctures and silver setae.   
Head 0.6 × as long as wide in dorsal view, matt, densely and finely punctate. Clypeus 2.2–2.4 × as broad as high, largely smooth, sparsely punctate dorsally, lower margin rounded (Fig. 40W). Face 1.6–1.8 × as broad as high, weakly convex medially in lateral view. Frons with some punctures united into some sharrow transverse grooves. Dorsal profile of gena as Fig. 39J. Occipital carina complete. Length of malar space 0.4 × as long as basal width of mandible. Mandible smooth apically, longitudinally striate medially, densely punctate basally. POL 0.95–1.1 × as long as OD. OOL 1.1–1.2 × as long as OD. Antenna with 44–45 flagellomeres. FL I 5.7 × as long as maximum depth, 2.2–2.5 × as long as FL II.  
Mesosoma polished and densely punctate. Pronotum with some longitudinal striae along collar. Epomia absent. Mesoscutum with indistinct notaulus. Epicnemial carina present laterally and ventrally, its dorsal end situated slightly behind of anterior margin of mesopleuron. Speculum with a smooth area (Fig. 31C). Mesopleuron with a rather wide concavity below speculum. Propodeum punctate and rugulose, lateromedian longitudinal carina and lateral longitudinal carina largely obscured. Transverse carinae absent. Area above sockets of hind coxa strongly convex. Fore wing length 12.8–14.2 mm. Areolet present, petiolated, received vein 2m-cu at the outer angle (Fig. 31D). Fore wing vein 1cu-a postfurcal to vein M&RS. Nervellus subvertical, intercepted anterior the middle. Tarsal claws simple. Hind femur 4.9–5.8 × as long as maximum depth in lateral view. Ratio of length of hind first to fifth tarsomeres 4.8–5.0: 2.0: 1.5–1.55: 0.9–0.95: 1.25.  
Metasoma finely punctate and coriaceous. T I 2.5–3.0 × as long as maximum width. T II 1.15–1.4 × as long as maximum width. Ovipositor sheath 0.15–0.2 × as long as hind tibia.  
Colouration (Figs. 31A–D). Body (excluding wings and legs) black. Clypeus dark reddish brown to reddish brown. Mandible and ventral surface of antenna more or less tinged with dark reddish brown. Posterior margin of T II, T III, T IV, and membranous part of metasomal sternite reddish brown to red. Reddish part of T II sometimes enlarged. Wings hyaline. Veins and pterostigma blackish brown except for yellowish-brown wing base. Legs blackish brown to black. Apices of fore and mid femora, fore tibia, fore tarsus, and basal part of mid tibia yellowish brown.  
 Male (n = 17). Similar to female. Body length 14.5–16.0 mm. Clypeus 2.0–2.2 × as broad as high. Length of malar space 0.25–0.35 × as long as basal width of mandible. Mandible smooth apically, punctate medially and basally. POL 1.0–1.3 × as long as OD. OOL 1.0–1.15 × as long as OD. Antenna with 41–45 flagellomeres. FL I 2.0 × as long as FL II. Fore wing length 11.6–13.0 mm. Face, clypeus, malar space, mandible except for teeth, palpi, and fore and mid coxae, trochanters, and trochantelli yellow (Figs. 31E, F). Hind tibia slightly paler than apical part (Fig. 31E). Yellowish brown part of fore and mid legs paler than female (Fig. 31E).

 Distribution. Japan (Hokkaido, Honshu, and Kyushu) and China.   
 Bionomics. Unknown.   
 Remarks. This is the first record of this species from Japan. Facial length/width and number of flagellar segments are slightly different from the type series (Sheng et al., 1999), while I conclude that these are intraspecific variations.
