Liu, Yang, Rasplus, Jean-Yves, Noort, Simon Van, Li, Zi & Huang, Dawei, 2017, Sycidiphaga, a new genus of Sycophaginae Walker, 1975 (Hymenoptera, Chalcidoidea, Agaonidae) associated with Ficus subgenus Sycidium in southern China, Zootaxa 4306 (1), pp. 91-107 : 94-95

Key to Sycophaginae genera of the world based on females

1 Petiole conspicuous, at least as long as broad ( Fig. 1 A); maxillary palpi four-segmented; labial palpi three-segmented; postmarginal vein conspicuous (may be short) ( Fig. 1 B); associated with Ficus subgenus Urostigma , section Malvanthera, Australasia...................................................................... Pseudidarnes Girault, 1927

- Petiole short and transverse ( Fig. 2 A); maxillary palpi at most three-segmented; labial palpi at most two-segmented, the second reduced as setae-like; postmarginal vein inconspicuous or absent ( Fig. 2 B)........................................ 2

2 Antennae inserted closer to median ocellus than to clypeal margin ( Fig. 3 A); supraclypeal area higher than clypeus and laterally well delimitated by line or groove (fig. 3A); ovipositor sheaths with a median constriction ( Fig. 3 B) (one exception: Anidarnes dissidens Farache & Rasplus, 2013 ); scrobal cavity including the median ocellus ( Fig. 3 A); associated with Ficus subgenus Urostigma section Americana, Neotropical region................................. Anidarnes Bouček, 1993

- Antennae inserted lower on head, at mid line of compound eyes or below ( Fig. 4 A); supraclypeal area as high as clypeus, poorly delimited laterally ( Fig. 4 A); ovipositor sheaths without a median constriction ( Fig. 4 B); scrobal cavity not including the median ocellus ( Fig. 4 A).............................................................................3

3 Malar sulcus present and conspicuous ( Figs 5 A, B); sculpture of the head and mesosoma can be reticulated or engraved ( Fig. 5 A), or completely smooth ( Fig. 5 B); associated with Ficus subgenus Sycomorus more rarely with subgenus Urostigma section Americana ; old world............................................................ Sycophaga Westwood, 1840

- Malar sulcus absent ( Fig. 6 A); sculpture of the mesosoma always reticulated or reticulate engraved ( Figs 6 A, B)..........4

4 Toruli contiguous, the distance between them much smaller than the torulus diameter ( Fig. 7 A); interantennal projection absent ( Fig. 7 A); postmarginal vein inconspicuous ( Fig. 7 B); head and mesosoma with metallic tinge ( Fig. 7 A); males always winged; associated with Ficus subgenus Urostigma , section Conosycea, Oriental region...................................................................................................... Conidarnes Farache & Rasplus, 2015

- Toruli separated from each other by about their diameter or more ( Fig. 8 A); interantennal projection present, sometimes inconspicuous ( Fig. 8 A); postmarginal vein always visible ( Fig. 8 B); head and mesosoma with metallic tinge or without, yellowish, brown to black; males apterous, only winged in the Idarnes incertus species-group.........................5

5 Pronotum medially more than 3/4 as long as mesoscutum ( Fig. 9 A); clypeus transverse ( Fig. 9 B), supraclypeal area not defined laterally by grooves ( Fig. 9 B); associated with Ficus subgenus Urostigma , section Malvanthera, Australasia............................................................................................ Eukoebelea Ashmead, 1904

- Pronotum shorter than 3/4 of the mesoscutum length ( Fig. 10 A); clypeus higher than wide or subquadrate ( Fig. 10 B), supraclypeal area defined laterally by deep or shallow grooves ( Fig. 10 B).........................................6
