Gonatocerus   is a worldwide group with numerous described extant species classified in several subgenera ( Triapitsyn et al. 2010). Its members are often the most commonly collected Mymaridae   in almost any habitat so it seems surprising that it has been recorded only once as a fossil, in Baltic amber by Meunier (1905).

The three species described below definitely belong to Gonatocerus   based onthe entire clava, 8-segmented funicle, similar sized gastral segments, short and probably narrow petiole, and 5-segmented tarsi (at least in the one species where they can be counted). Because they all appear to have a rhomboidal dorsellum they would be classified either in Gonatocerus (Gonatocerus)   or in Gonatocerus (Cosmocomoidea)   , but not Gonatocerus (Lymaenon)   , the most common extant subgenus because it has a narrow, strap-shaped dorsellum or Gonatocerus (Gastrogonatocerus)   because the ovipositor does not project forward under the mesosoma.
