Opius dablus Wharton, 2013
The fore wing 1RS is longer in this species than in others of this species group, at the lower end of the range for the 1M/1RS ratio given in the species group diagnosis in Wharton and Norrbom (2013). In other species in this group, the ratio is near the upper end of the range. Similarly, fore wing m-cu is more strongly postfurcal in O. dablus, resulting in a lower 3RSa/2RS ratio than in most other members of this species group.
Members of the Opius baderae species group (to which this species belongs) will key to Opius (Opius) in the subgeneric keys of Fischer (1972), 1977, (1999) because of the completely concealed labrum, unsculptured precoxal sulcus, and absence of a midpit on the mesoscutum. They differ from the type species of Opius (i.e., Opius s.s.) in lacking a basal lobe ventrally on the mandible, and thus would key to Phaedrotoma Foerster in the classification of van Achterberg and Salvo (1997) and Li et al. (2013) and the key to genera in Fischer (1999). In members of the baderae group the propodeum is also almost completely unsculptured.
There are no specimens currently determined for this OTU, or those specimens determined for this OTU are not yet mappable.
