Feron izabellae Melika, Nicholls & Stone, sp. nov.
Gall (Fig. 227). A small (up to 5mm diameter) monolocular spangle gall on the underside of leaves. Initially a disc-shaped gall lying flat against the leaf surface, pink in middle and around the edge with cream circle in between. When galls mature the opposite sides of the disc fold up and touch. Informally called the pink bowtie gall wasp in Russo (2006, 2021).
Biology. Only the asexual generation is known which induces spangle leaf galls on Q. berberidifolia, Q. douglasii, Q. dumosa (= Q. durata), Q. garryana (all section Quercus, subsection Dumosae). Galls mature in September–October. Adults emerge soon afterwards.
