1. Hind tibia completely black ( Fig. 6 ). Tegula black ( Fig. 7 ). Palpi blackish brown ( Fig. 6 ). Propodeal carinae strongly developed ( Figs 8 , 22 ). Fore wing with postero-distal corner of second discoidal cell in form an acute angle (80°). T I in profile dorsally with an obtuse angulation ( Fig. 23 ).................... P. nigrifemur

—. Hind tibia with a conspicuous yellowish brown or reddish brown area ( Figs 1, 9 ). Palpi and tegula yellow to yellowish brown ( Figs 1, 2, 9, 10 ). Propodeal carinae strongly developed ( Figs 11 , 26 ) or partly obscured ( Figs 3 , 16 ). Fore wing with postero-distal corner of second discoidal cell in form an acute to right angle (85–90°) ( Fig. 4 ). T I in profile dorsally of T I without an obtuse angulation ( Figs 17, 27 ).................. 2

2. Apical margin of clypeus with a pair of lateral margined area and a median weak, smooth convexity ( Fig. 15 ). Propodeal carinae partly obscured ( Figs 3 , 16 ). Tegula light yellow ( Fig. 2 ). Ovipositor sheath distinctly longer than (1.4×as long as) hind tibia............................................. P. monticola sp. nov.

—. Apical margin of clypeus simply arched, without a pair of lateral margined area and a median weak, smooth production ( Fig. 25 ). Propodeal carinae strongly developed ( Figs 11 , 26 ). Tegula dark yellow to brown ( Fig. 10 ). Ovipositor sheath almost as long as hind tibia............................................ P. sepiellus
