Head 0.55–0.6 (HT: 0.6) × as long as wide in dorsal view. Clypeus 1.9–2.0 × as wide as long; slightly convex in lateral view; punctate dorsally, smooth ventrally; lower margin weakly rounded in frontal view, sharp and narrowly reflecting in lateral view. Face 0.35–0.4 × as long as minimum width; weakly convex medially; matt and punctate. Frons slightly concave above antennal sockets; finely punctate except for smooth areas above antennal sockets. POL 1.5–1.8 × as OD. OOL 1.05–1.6 × as OD. Gena and occiput finely punctate. Dorsal profile of gena rounded in dorsal view; width gradually narrowing posteriorly ( Fig. 46F). Occipital carina complete. Malar space 1.2–1.5 × as long as basal width of mandible. Mandible flat at base; lower tooth equal in length of upper tooth. Antenna with 22–24 flagellomeres; not flattened and tapped. FL I 3.8–4.1 × as long as maximum depth in lateral view, 1.05–1.15 × as long as FL II.

Mesosoma. Pronotum longitudinally striate except for finely and densely punctate area along dorsal margin and smooth area of collar ( Fig. 46G). Epomia short and indistinct. Mesoscutum finely punctate except for median area densely punctate. Notaulus long and sharp; posterior end reaching centre of mesoscutum. Scutellum punctate ( Fig. 46I); weakly convex in lateral view. Mesopleuron obliquely or longitudinally striate or foveolate; with conspicuous smooth area around speculum. Epicnemial carina present laterally and ventrally. Sternaulus deep in entire length of mesopleuron. Metapleuron with complete juxtacoxal carina. Propodeum largely irregularly rugulose; with all carinae; anterior transverse carina sometimes partly indistinct; area superomedia defined ( Fig. 46I), ca. 1.5 × as long as maximum width; apophysis absent; spiracle round. Fore wing length 4.75–6.3 mm. Areolet as long as maximum width; longer than half length of vein 2m-cu; width slightly narrowing anteriorly; received vein 2m-cu at near middle; anterior width longer than half length of vein 2m-cu ( Fig. 46H). Fore wing vein 1cu-a interstitial to vein M&RS. Nervellus subvertical; intercepted near posterior end of vein. Hind femur reticulate coriaceous; 5.25–5.8 × as long as maximum depth in lateral view. Tarsal claws simple.

Metasoma. T I 2.0–2.25 × as long as maximum width; largely coriaceous with longitudinal striae on postpetiole; latero-median carina weakly and partly present; dorso-lateral carina present, section above spiracle indistinct. Spiracle of T I behind the mid-length of T I. T II 0.8–0.9 × as long as maximum width; matt. Thyridium present; close to anterior margin of T II; slightly depressed; ca. 2.0 × as wide as length. T III to T VII weakly to slightly coriaceous. Ovipositor sheath 1.3–1.5 × as long as hind tibia, 2.25–2.6 × as long as T I. Ovipositor upcurved; apex sharp and without minute teeth dorsally; apex of lower valve with teeth ( Fig. 79O).

Colouration ( Figs. 46A–I). Body (excluding wings) black to blackish-brown. Setae silver. Subapical part of mandible tinged with reddish-brown. FL VI to FL IX (or X) with white markings. Basal part of antenna (baseward than white band; especially from scape to FL II) sometimes tinged with reddish-brown. Tibial spurs of all legs ivory. Fore and mid legs except for tibial spurs sometimes changed colouration; partly/entirely black, brown, reddish-brown, or reddish-yellow. Hind leg except for tibial spurs also changed colouration like as fore and mid legs but apical parts of femur and tibia always blackish-brown to black, base of tibia always white, and tarsus always darkened. Median part of T VI to T VIII white to ivory. Ovipositor reddish-brown. Wings hyaline. Veins and pterostigma blackish-brown to brown except for yellowish wing base.

Male (n = 4). Similar to female except for colouration ( Figs. 47A–D). Clypeus 2.0–2.2 × as wide as long. Face 0.5 × as long as minimum width. Malar space 1.0 × as long as basal width of mandible. Antenna with 26–27 flagellomeres; tyloids on FL X to FL XIV ( Fig. 47D). FL I 2.8–2.95 × as long as maximum depth in lateral view, 1.05–1.2 × as long as FL II. Fore wing length 5.1–5.8 mm. T I 2.4–2.55 × as long as maximum width. T II 0.9–1.0 × as long as maximum width. Antenna without white band. Clypeus except for apico-median black area, mandible except for teeth, pair of markings along facial orbit, ventral spot of scape, basal segments of palpi and tegula ivory. Posterior margins of each metasomal tergite narrowly tinged with ivory. Legs black; trochanter and trochantellus partly tinged with yellowish-brown to ivory; fore femur more or less tinged with brown to yellowish-brown; bases of femora and tibiae yellowish-brown to ivory; each tarsal segment of all leg narrowly tinged with brown to yellowish-brown.

Distribution. Japan (Hokkaido, Honshu, Hachijojima Is., and Shikoku).

Bionomics. Host unknown. Adult wasps usually collected grassland in open-habitat.

Remarks. This is the first description of the male of this species. The colouration of female legs in Pa. microstriatella shows relatively large intraspecific variation in this group, i.e., largely red to largely black. Both specimens with red legs and with black legs are inseparable based on other characters and the colour variation are gradually changed from red to black. Species exhibiting such colour variation are often known to be found in open-habitat (e.g., Itoplectis naranyae ( Ashmead, 1906) and Thrybius togashii Kusigemati, 1982 ) ( Shin & Yasumatsu, 1970; Matsumoto & Saigusa, 2001), which may be related to the fact that this species is found in grassland. In addition, the character states of this species with red legs are completely same to that of Pa. maruyamensis . Thus, I conclude that Cratocryptus microstriatellus Uchida, 1952 under Microcryptus maruyamensis Uchida, 1930 (= Pa. maruyamensis ) (syn. nov.).
