The female micro-wasp in mid-Cretaceous Burmese amber is described as a new genus and species in the extinct family Caradiophyodidae fam. nov. (Hymenoptera: Platygastroidea). Features of the specimen are its small body size (1.3 mm), no elbows, elongated, 15-segmented antennae, a deep cleft in the top of its head, a tarsal formula of 5-5-5, a reduced venation with a small pterostigma but no uncus in the forewing, no anal lobe in the hind wing, and a possible coiled ovipositor in the metasoma. Large unidentified expanded structures, considered to be possible seeds, plant secretions, or host eggs, are attached to each antenna.
