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

 

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

 


2. Antennae inserted closer to median ocellus than to clypeal margin (A); supraclypeal area higher than clypeus and laterally well delimitated by line or groove (A); ovipositor sheaths with a median constriction (B) (one exception: Anidarnes dissidens Farache & Rasplus, 2013); scrobal cavity including the median ocellus (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 (a); supraclypeal area as high as clypeus, poorly delimited laterally (a); ovipositor sheaths without a median constriction (b); scrobal cavity not including the median ocellus (a) …3

 


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

 

- Malar sulcus absent (a); sculpture of the mesosoma always reticulated or reticulate engraved (a, b) …4

 


4. Toruli contiguous, the distance between them much smaller than the torulus diameter (A); interantennal projection absent (A); postmarginal vein inconspicuous (B); head and mesosoma with metallic tinge (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 (a); interantennal projection present, sometimes inconspicuous (a); postmarginal vein always visible (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 (A); clypeus transverse (B), supraclypeal area not defined laterally by grooves (B); associated with Ficus subgenus Urostigma, section Malvanthera, Australasia …Eukoebelea Ashmead, 1904

 

- Pronotum shorter than 3/4 of the mesoscutum length (a); clypeus higher than wide or subquadrate (b), supraclypeal area defined laterally by deep or shallow grooves (b) …6

 


6. Wings with dense and long pilosity (A); interantennal projection conspicuous, blade-like, extending well above the level of the toruli (B); parastigma inflated and surrounded by a slight infuscation of the wing membrane (A); body black without metallic tinge; associated with Ficus subgenus Sycidium, section Sycidium, Eurasia …Sycidiphaga Liu, Rasplus & Huang, 2017.

 

- Wings with sparse and short pilosity (a), stigmal vein with adstigmal setae (a); interantennal projection not blade-like (b); parastigma not surrounded by a slight infuscation (a); body with metallic tinge; when non-metallic (black, yellow, brown) ovipositor sheaths much shorter than body length; associated with Ficus subgenus Urostigma, section Americana, Neotropical region …Idarnes Walker, 1843
