Grammospila Foerster, 1863: 269. Type species (by monotypy): Alysia isabella Haliday, 1838 [lost?].

Paraorthostigma Königsmann, 1972: 25. Type species (by monotypy): Paraorthostigma tirolense Königsmann, 1972 [examined]. Synonymised with Dapsilarthra Foerster, 1863 by van Achterberg (1983) and with Grammospila Foerster, 1863 by van Achterberg (2014).

Description.

Antenna with 27-41 segments, third segment 1.2-1.5 times as long as fourth segment (in Palaearctic spp.); head comparatively robust in dorsal view (Fig. 11 ); anterior tentorial pit large and with triangular flat area between pit and eye above curved up ventral rim (Figs 3 , 10 ); area between mandibular base and ventro-posterior margin of eye convex or flat, without oblique depression, without malar suture; anterior tentorial pits concave, pit-shaped, and remaining removed from eyes; mandible with 3 teeth or lobes; ventral margin of mandible straight (Fig. 2 ); notauli absent posteriorly; mesoscutum with medio-posterior depression; length of vein 3-SR of fore wing more than 1.2 times vein 2-SR; length of vein r of fore wing 0.2-0.3 times vein 2-SR; diagonal width of first discal cell of fore wing often 1.4-1.6 times vein 1-M; vein 2-1A of fore wing sclerotized, as usually vein CU 1b; vein 1-SR of fore wing distinct, resulting in a petiolate first discal cell; vein r of fore wing emitted from basal 0.3-0.5 of pterostigma; first subdiscal cell of fore wing parallel-sided or nearly so; vein m-cu of hind wing absent; pterostigma narrowly elliptical; first metasomal tergite parallel-sided behind spiracles or nearly so, with deep dorsope and laterope, its spiracles facing dorsad; apical third of ovipositor sheath evenly setose.

Biology.

Endoparasitoids of Agromyzidae and Scathophagidae larvae. Grammospila isabella (Haliday), has been reared from Scathophagidae ( Americina vittata (Meigen, 1826) mining in Paris sp.; first record; RMNH).

Distribution.

Palaearctic and NE Oriental. Seven species.

Key to species of the genus Grammospila Foerster

1	Antenna of ♀ 0.9-1.3 times as long as body and 0.9-1.1 times as long as fore wing; if 1.1 times fore wing then vein 1-R1 of fore wing 0.8 times as long as pterostigma; hind femur largely dark brown	2
-	Antenna of ♀ 1.4-1.9 times as long as body and 1.1-1.6 times as long as fore wing; if 1.1 times fore wing then vein 1-R1 of fore wing about as long as pterostigma; hind femur brownish yellow	3
2	Vein CU1b of fore wing present, resulting in a closed first subdiscal cell; antenna approx. 1.3 times as long as body and 1.0-1.1 times as long as fore wing; vein r issued near basal 0.3 of pterostigma; marginal cell comparatively narrow basally; [collected at approx. 1600 m]	G. tirolensis ( Königsmann, 1972)
-	Vein CU1b of fore wing absent, resulting in partly open first subdiscal cell (Figs 1 , 4 ); antenna approx. 0.9 times as long as body or fore wing; vein r issued near basal 0.4 of pterostigma (Fig. 4 ); marginal cell wide basally (Fig. 4 ); [collected at approx. 1200 m]	G. martae sp. n.
3	Notauli complete; body with many long setae (including mesoscutum and mesosternum); first subdiscal cell of fore wing widened distally and vein 1-CU1 widened; [third antennal segment 1.4-1.5 times as long as fourth segment; vein m-cu of fore wing antefurcal (not postfurcal as mentioned in original (Chinese) description)]; Oriental (East China, Fujian)	G. eurys (Chen & Wu, 1994)
-	Notauli largely absent on mesoscutal disc (cf. Fig. 6 ); body with rather sparse and medium-sized setae (including mesoscutum and mesosternum); first subdiscal cell of fore wing parallel-sided and vein 1-CU1 slender; Palaearctic	4
4	Penultimate segment of antenna of ♀ 1.7-2.0 times as long as wide; base of hind coxa and second metasomal tergite dark brown or blackish	G. fuscula (Griffiths, 1968)
-	Penultimate segment of antenna of ♀ 2.5-3.2 times as long as wide; base of hind coxa and second tergite brownish yellow	5
5	Antenna with 38-41 segments and approx. 1.6 times as long as fore wing; length of fore wing 3.0-3.5 mm; vein SR1 of fore wing about twice as long as vein 3-SR	G. isabella (Haliday, 1838)
-	Antenna with 27-33 segments and 1.3-1.4 times as long as fore wing; length of fore wing 2.0-2.5 mm; vein SR1 of fore wing approx. 2.5 times as long as vein 3-SR	6
6	Clypeus comparatively narrow and rather convex (Figs 16 , 17 ); metasoma darkened or dark brown apically (Fig. 15 )	G. rufiventris (Nees, 1814)
-	Clypeus comparatively wide and flattened; metasoma yellow apically	G. ochrogaster ( Szépligeti, 1898), stat. n.
