A recent DNA-based assessment of the psyllid fauna of New Zealand recorded high genetic variation between populations that were expected to belong to the same psyllid species. Among these, a number of populations of the kōwhai psyllid Psylla apicalis (Ferris & Klyver, 1932), from a kōwhai species, Sophora microphylla Aiton (Fabaceae), presented high genetic variability. This gave new endorsement of an 87-year-old observation made by the entomologists Ferris and Klyver who, when describing the kōwhai psyllid, from Sophora tetraptera J.S. Muell., suggested that morphological variations could support more than one species. Accordingly, the morphological assessment conducted here, together with the genetic information now available, resulted in the description of Psylla frodobagginsi sp. nov. as a second New Zealand endemic psyllid species hosted by S. microphylla.
最近一项基于 DNA 的新西兰叶蝉区系评估记录表明,预期属于同一叶蝉种的种群之间存在较高的遗传变异。在这些种群中,一些产自 Sophora microphylla Aiton(豆科)的新西兰 kōwhai 叶蝉 Psylla apicalis(Ferris & Klyver,1932)种群表现出较高的遗传变异性。这为 87 年前昆虫学家 Ferris 和 Klyver 的一个观察结果提供了新的支持,他们在描述 Sophora tetraptera J.S. Muell. 的 kōwhai 叶蝉时,曾提出形态变异可能支持一个以上的物种。因此,这里进行的形态评估,加上现在可用的遗传信息,导致描述了 Psylla frodobagginsi sp. nov. 为第二个在 Sophora microphylla 上寄生的新西兰特有叶蝉物种。
