Notaulus long and sharp; posterior end reaching centre of mesoscutum ( Fig. 44D). Scutellum punctate; weakly convex in lateral view. Mesopleuron with conspicuous smooth area around speculum. Epicnemial carina present laterally and ventrally. Sternaulus deep in entire length of mesopleuron. Metapleuron without juxtacoxal carina. Propodeum with all carinae; area superomedia defined, as long as maximum width; apophysis weak and obtuse; spiracle round. Fore wing length 6.5 mm. Areolet as long as maximum width; longer than half length of vein 2m-cu; width gradually narrowing anteriorly; received vein 2m-cu at near middle; anterior width longer than half length of vein 2m-cu ( Fig. 44F). Fore wing vein 1cu-a interstitial to vein M&RS. Nervellus subvertical; intercepted near posterior end of vein. Hind femur reticulate coriaceous; 5.6 × as long as maximum depth in lateral view. Tarsal claws simple.

Metasoma. T I 2.35 × as long as maximum width; lateromedian carina absent; dorso-lateral carina absent. Spiracle of T I behind the mid-length of T I. T II 0.9 × as long as maximum width. Thyridium present; close to anterior margin of T II; slightly depressed; ca. 3.0 × as wide as length. Ovipositor sheath 1.3 × as long as hind tibia, 2.55 × as long as T I. Ovipositor slightly upcurved ( Fig. 44A); apex sharp and without minute teeth dorsally; apex of lower valve with teeth ( Fig. 79M).

Colouration ( Figs. 44A–H). Body (excluding wings) black to blackish-brown. Setae silver. Subapical part of mandible tinged with reddish-brown. Face with pair of dark yellowish-brown spots between antennal sockets and eye. FL VI to FL IX with white markings. Fore and mid tibiae and tarsi partly tinged with brown. Apical half of hind TS II, hind TS III, and hind TS IV white. Median membranous part of T VII white. Ovipositor reddish-brown. Wings hyaline. Veins and pterostigma blackish-brown to brown except for yellowish wing base.

Male. Unknown.

Distribution. Japan (Honshu).

Bionomics. Unknown.

Etymology. The specific name is from Latin “ albi ” plus “ tarsale ”, referring to the white tarsal segment of hind tarsus.

Remarks. This species resembles Pa. pleuralis albomaculata and Pa. nigra sp. nov. but can be distinguished by the well-developed propodeal carinae (anterior transverse carina absent in Pa. nigra ), the punctures on face indistinct (distinct in Pa. nigra ), the ovipositor sheath 1.3 × as long as hind tibia (longer than 1.5 × in Pa. pleuralis albomaculata and Pa. nigra ), the black tegula (ivory in Pa. pleuralis albomaculata ), and the hind tarsus with white band (entirely black in Pa. pleuralis albomaculata and Pa. nigra ).
