Background A gall midge species (Diptera: Cecidomyiidae) inducing leaf bud galls on Magnolia kobus DC. var. borealis Sarg. (Magnoliaceae) was found in Hokkaido and northern Honshu, Japan. New information Based on its morphology, the species is regarded as an undescribed species of the genus Pseudasphondylia Monzen (Cecidomyiinae, Cecidomyiidi, Asphondyliini). The species is herein described as Pseudasphondylia saohimea Matsuda, Elsayed and Tokuda sp. n. The new species is easily distinguishable from its congeners by the number of adult palpal segments and the shape of the male terminalia and larval spatula.

与 Magnolia kobus DC 相关的 Pseudasphondylia 新种（双翅目： Cecidomyiidae）。变种。北极星萨尔格。（木兰科）在日本

背景 一种瘿蠓物种（双翅目：Cecidomyiidae）在 Magnolia kobus DC 上诱导叶芽瘿。变种。北极星萨尔格。（木兰科）发现于日本北海道和本州北部。新信息 根据其形态，该物种被认为是 Pseudasphondylia Monzen 属（Cecidomyiinae、Cecidomyiidi、Asphondyliini）的未描述物种。该物种在本文中被描述为 Pseudasphondylia saohimea Matsuda、Elsayed 和 Tokuda sp。n. 通过成年触须节的数量以及雄性末端和幼虫刮刀的形状，可以很容易地将新物种与其同族区分开来。
