Dinera grisescens vs Solieria females
This is a confusion pair that I have wanted to separate for a while because they can be a bit tricky because they both have brown-dusted bodies and 2 pairs of scutellar bristles. But it looks like the distinction breaks down as follows:
| Dinera grisescens | Solieria pacifica (but possibly all Solieria spp.) |
| Median vein meets the wing edge at vein r4+5 or making a very short petiole by touching r4+5 | Wing cell R5 open |
| m-cu at almost the same angle as the median vein after the bend | m-cu at very different angles to the median vein after the bend |
| Tergite 1+2 usually without median marginals | Tergite 1+2 median marginals always present |
| Antenna 3 much shorter than the gena | Antenna 3 as long as or longer than the gena |
| Parafacial much wider than the width of antenna 3 | Parafacial narrower or as wide as the width of antenna 3 |
