Abstract

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.

摘要

描述了一个新的属，Grahamstoneia Melika Nicholls，gen. nov.，并附有一个新种，G. humboldti Melika Nicholls，sp. nov.，无性世代。这个新分类单元出现在西南近北极地区，在 Quercus 节 Protobalanus 内的两个物种上诱导虫瘿（Q. vacciniifolia Kellogg 和 Q. chrysolepis Liebm.），其生态和分布与密切相关的 Heteroecus Kinsey 属共享。本文给出了新属和新种的描述、诊断、生物学和寄主关系。新分类单元得到了形态和分子数据的支持。
