Identification
Some diagnostic characters for genus Enicospilus (cf. key and figures 16 & 25 in Broad(2006), and reference images here) are:
the discosubmarginal cell (horsehead-shaped cell below the leading wing edge) extends beyond vein 2m-cu;
transparent oval (inside discosubmarginal cell) in the otherwise papillate wing [note at least some Enicospilus spp. have two spots in this oval];
adventitious (or "spurious") vein in cell 3Cu, parallel to the wing margin.
