Distribution
|
Madagascar, South Africa. Also Holarctic
& Neotropical regions. |
Biology
|
Usually parasitoids of coleopteran stem
borers or gall makers (Buprestidae,
Cerambycidae, Coleophoridae, Mordellidae), but also attack
lepidopteran (Gelechiidae, Noctuidae,
Pieridae, Pyralidae, Scythridae) and dipteran larvae (Tephritidae). |
Diagnosis
|
Body slender. Occipital carina dorsally incomplete,
the free upper ends down curved. Scutellum weakly to moderately
convex, often with a weak lateral carina. Propodeum completely
areolated or nearly so. First radial cell short. Areolet absent.
Vein Rs&M opposite or slightly basal to vein cu-a,
vein rs-m opposite to basal to 2m-cu by 0.5 its
length. Hind wing with vein Cu + cu-a usually broken, vein
Cu1 spectral to absent. Tergite I with long and shallow glymma,
its lower edges separated and parallel, rarely almost touching.
Thyridium absent. Epipleurum of tergite II narrow, separated by a
crease, turned under. Apex of male gonosquama with a long ventral
asymmetric lobe, this separated by a concave area from a dorsal
tooth or short lobe near base. Ovipositor tip straight, decurved, or
weakly sinuate (Rousse etal., 2011). |
