Zapatella quercusmedullae (Ashmead) comb. n. Figures 46-51

Cynips quercusmedullae Ashmead, 1885 (females, galls). Andricus (Andricus) medullae Ashmead, 1885. Callirhytis quercusmedullae (Ashmead) ( Burks 1979). Andricus cryptus Ashmead, 1887 (synonym in Dailey and Menke 1980).

Material examined.

One paratype female: 'Jacksonville; collector Ashmead; Paratype No. 1497; Andricus medullae Ashm. (handwritten label)'.

Only the asexual generation is known. It induces stem swelling galls, in spring, on Quercus incana Bartram (= Quercus cinerea Raf.), Quercus marilandica (L.) Münchn. and Quercus myrtifolia in the USA (Florida, Alabama, Georgia, Missisipi, Texas) ( Burks 1979). The adults emerge the following year in February and March ( Ashmead 1885a, b; Weld 1959).

The female, like the previous species, has the notauli incomplete, extending to half of the mesoscutum length, with darker lines that resemble notauli reaching the anterior margin of the mesoscutum. The median mesoscutal line is absent. The prominent part of the ventral spine of the hypopygium is 6.2 times as long as broad ventrally. See also the key to Zapatella species.
