Two paratype females: ‘Placerville Cal., May 21’18; 1615; Paratype No. 27223 USNM; Eumayria herberti’ and ‘Placerville Cal.; cut out May 13; 1615; Paratype No. 27223 USNM; Eumayria herberti’.
Only the asexual generation is known. It induces stem swelling galls on Quercus agrifolia Née, Quercus kellogii Newb., Quercus wislizeni A. DC in California (USA) (Weld 1926, Burks 1979). Larval chambers (cells) are nested in the peripheral layer of wood, just under the bark of vigorous shoots 2cm or less in diameter. Adults emerge in late May (Weld 1926).
The female is unifromly reddish brown, including the metasoma. The notauli are complete, always reaching pronotum, deeply impressed; the median mesoscutal line is short, extending to 1/4 of the mesoscutum length, beyond which it is indicated by a dark line only. The metasoma has a ring of very dense white setae at the base of the 2nd metasomal tergite, interrupted dorsally; the metasoma is slightly higher than long in lateral view. The 2nd metasomal tergite is smooth, shiny, without pnctures, while the next tergites have micropunctures. The ventral spine of the hypopygium is hidden under the tergites, its prominent part 6.1 times as long as broad ventrally. See also the key to Zapatella species.
