Species are amongst the largest parasitoid wasps in the tribe Alysiini (Alysiinae).

[1] Generally, Dinotrema species are parasitoids of the larvae of Diptera predominantly from families Anthomyiidae, Phoridae and Platypezidae, groups considered as pests.

[2] Dinotrema comprises a large number of species described from Afrotropical, Australasian, Nearctic, Neotropical, Oceanic, Oriental and Palaearctic (mainly from Western Europe) regions.

[3] This genus has tridentate and small mandibles, with paraclypeal fovea short, not reaching ventral edge of eyes.

It is differentiated from the genus Aspilota by the short size of the paraclypeal fovea far separated from the inner margin of the eye.
