描述了一个新属，格雷厄姆石蜂属（Grahamstoneia Melika Nicholls，新属），以及一个新种，洪堡格雷厄姆石蜂（G. humboldti Melika Nicholls，新种），无性世代。这个新分类群出现在新北界西南部，在栎属原糙果栎组（Quercus section Protobalanus）的两个物种（越橘叶栎（Q. vacciniifolia Kellogg）和黄鳞栎（Q. chrysolepis Liebm.））上诱导虫瘿，其生态和分布与近缘的异石蜂属（Heteroecus Kinsey）相同。给出了新属和新种的描述、鉴别特征、生物学特性以及寄主关联。新分类群得到了形态学和分子数据的支持。
A new genus, Grahamstoneia Melika Nicholls, gen. nov., with one new species, G. humboldti Melika Nicholls, sp. nov., asexual generation, is described. This new taxon occurs in the south-western Nearctic, inducing galls on two species within Quercus section Protobalanus (Q. vacciniifolia Kellogg and Q. chrysolepis Liebm.), an ecology and distribution shared with the closely related genus Heteroecus Kinsey. Descriptions, diagnoses, biology, and host associations for the new genus and species are given. The new taxon is supported by morphological and molecular data.
