Paroplitis

Key to world species of Paroplitis

1 T2 partially and slightly sculptured; propodeum evenly rugose on its entire surface, without distinctive carination [western Palaearctic region: Austria (Tirol, 2400m)]......................................... Paroplitis rugosus Papp, 1991

- T2 mostly smooth and shiny (Figs 8, 15, 19); propodeum only partially rugose, with median carina visible on at least anterior 0.5, and sometimes with complete or partial transverse carina (Figs 7, 8, 15, 19)................................... 2

2(1) Fore wing areolet quadrangular and relatively large, its maximum height 1.1 x vein r length (Fig 5); fore wing with vein 2CUa tubular on its anterior 0.3–0.5 [Nearctic region: Canada (British Columbia, Yukon) and United States (Alaska)]................................................................................... Paroplitis beringianus Mason, 1981

- Fore wing with areolet triangular and relatively small, its maximum height at most 0.7 x vein r length, usually much less (Figs 10, 12, 17); fore wing with vein 2CUa entirely nebulous [western Palaearctic or Oriental regions]..................... 3

3(2) Propodeum usually without trace of transverse carina (Fig. 19); fore wing with areolet very small, its maximum height 0.2 x vein r length, its maximum width 0.2 x vein r length (Fig. 17) [western Palaearctic region: Azerbaijan, Belgium, Finland, France, Germany, Hungary, Poland, Romania, Russia (Krasnodar Kray), Sweden, Switzerland, Ukraine, United Kingdom]........................................................................... Paroplitis wesmaeli (Ruther, 1860)

- Propodeum with a more or less complete and defined transverse carina (Fig 15); fore wing with areolet larger, its maximum height 0.5–0.7 x vein r length, its maximum width 0.6–0.7 x vein r length (Figs 10, 12) [Oriental region, between 1700–2400 m]................................................................................................ 4

4(3) Scape, tegula, humeral complex, and legs entirely yellow (except for anterior 0.5–0.7 of metacoxa which is brown) (Fig. 9); fore wing with vein R1 as long as or longer than pterostigma length, and much longer than distance delimited between end of vein R1 and end of vein 3RSb (Fig. 10) [Oriental region: Philippines (Luzon Island) and southern Vietnam (Lam Dong)]............................................................................. Paroplitis luzonicus Mason, 1981

- Scape, tegula, humeral complex, and most of legs entirely brown to dark brown (Figs 11–15); fore wing with vein R1 shorter than pterostigma length and same length (at most slightly larger) than distance delimited between end of vein R1 and end of vein 3RSb (Fig. 12) [Oriental region: northern Vietnam (Tonkin)]........................................................................................ Paroplitis vietnamensis van Achterberg and Fernández-Triana new species
