Many, but not all, sceliotracheline genera possess foamy structures, which, among platygastroids, are limited to Platygastridae( Lahey et al. 2019b; Chen et al. 2021). The following characters can be loosely used for a broad definition: the form of the female antennal clava, which is often abrupt, massive and usually obviously 3- or 4-merous; a very stout habitus, similar to the form present in the subfamily Telenominae, with the metasoma not laterally carinated (there is no impressed submarginal ridge as found in Scelioninaeand Teleasinae), at most a sharp lateral edge. There is a very short (sometimes almost absent) to a long, well developed (especially in species with 10 antennomeres) apically knobbed submarginal vein in  Fidiobia(Ovidiu Popovici pers. comm.), except in the brachypterous  F. pronotata Szabo, and a longer submarginal vein in  Allotropathat has a spectral knob. In  PlatygastoidesDodd, at least in the type of the genus,  P. mirabilis, the submarginal vein is knobbed apically, but far more spectral. Sometimes there is a spectral submarginal vein present in  Amitus, but this is never knobbed apically. Fore wing venation is absent in  Isoliaand  Sceliotrachelus, except for  S. karooensissp. nov., which has a spectral submarginal vein. The Australian  Platygastoidescombines some characters of  Fidiobia,  Plutomerusand  Isolia.
