(Figs 4–6)
Type material: Holotype female in amber piece DZUP Bur-1159. The wasp is well preserved without any apparent deformations; it is mostly articulate, except for the left proleg, which is detached from the femur but placed very near the wasp body; the left antenna lacks its distal three flagellomeres. Syninclusions: one Serphitidae, two Platygastroidea, the remainder of what seems a scolebythid wasp (most of the body was already sanded off), plus abundant stellate plant trichomes.
Description: Holotype female. Measurements (in mm): approximate body length: 3.05; maximum head width: 0.75; maximum head length: 0.68; minimum interocular distance: 0.33. Colour: head and mesosoma mostly black. Mouthparts, pedicel, flagellum and legs light brown; scape dark brown. Wings hyaline, with light brown veins. Metasoma reddish-brown. Pilosity: short and dense overall. Longer setae on tibiae not surpassing one-half the maximum tibial width. Spine-like setae on the apex of tarsomeres and scattered on the first tarsomere of mesotarsus. Wingmembranehomogeneouslysetose, setaeshorterthanwidth of vein M + Cu; anterior margin of forewing with setae shorter than width of vein C. Sculpturing: integument mostly smooth, without conspicuous ornamentations; metapostnotum apparently with longitudinal carinae; lateral surfaces of propodeum rugose. Structure: antennal sockets separated from each other by about one-half socket width. Compound eye about twice as long as maximum width. Ocellar triangle below upper tangent of eyes; lateral ocelli separated from inner orbit by about 1.5× mid-ocellus width. Vertex extending beyond lateral ocelli by about one mid-ocellus width. Scape about 3× as long as wide; pedicel about twice as long as wide; F1 slightly shorter than pedicel; F2 with about one-half F1 length; remaining flagellomeres subequal to F 2 in length; flagellum thicker between F5-F7. Profemur 3× as long as its maximum width; first tarsomere of proleg 0.7× as long as protibia. First tarsomere of mesoleg 0.8× as long as mesotibia. Metafemur thicker on basal half, 2.5× as long as maximum width. First tarsomere of metaleg 0.7× as long as metatibia. Forewing: pterostigma 4× as long as maximum width; 2rs-m inserted near basal third of marginal cell; 1st medial cell about twice as long as width. Hindwing: with four distal hamuli. Dorsal surface of T1 as long as 0.8× the exposed surface of T2.
Male: Unknown.
Etymology: The specific epithet is based on the alternative name of the Titaness Theia, who, in Greek mythology, endowed jewels with their brilliance and value. Name in apposition.
