Key to European amber genera of Encyrtinae (females)

1 (4) Postmarginal vein shorter than marginal vein.

2 (3) Hypopygium extending past apex of syntergum.................................... Protaphycus Simutnik, 2022 3 (2) Hypopygium not extending apex of syntergum................................. Electrocerus Simutnik , gen. nov. 4 (1) Postmarginal vein not shorter than marginal vein.

5 (6) Row of filum spinosum double, consisting of 9 setae..................................... Efesus Simutnik, 2020 6 (5) Row of filum spinosum single, consisting of 2–6 setae.

7 (8) Funicle as long as clava. All funicle segments wider than long.......................... Dencyrtus Simutnik, 2018 8 (7) Funicle longer than clava. At least some funicle segments longer than wide.

9 (10) Mesoscutum with large, deep, rare punctures..................................... Ektopicercus Simutnik, 2020 10 (9) Mesoscutum without large punctures.

11 (12) Antenna thin, filiform. Clava about 5.5× as long as wide......................... Protocopidosoma Simutnik, 2017 12 (11) Antenna not filiform, clavate. Clava about 3× as long as wide.......................... Rovnosoma Simutnik, 2015

The key does not include the genus Glaesus Simutnik, 2014 , which is only known from a male specimen. Its postmarginal vein is longer than the marginal vein.
