Species of the family Phytoseiidae are known as predatory mites, some of them being used in crops to control mite pests, all around the world. Neoseiulus (=Cydnodromus) californicus is among the most commonly used Phytoseiidae species in biological control programs, especially in vineyards, orchards and vegetable fields. This species is distributed world-wide but has never been reported from Australia. On the other hand, specimens morphologically close to N. californicus have been assigned to a species called Neoseiulus wearnei, only reported from Australia. Investigations based on morphological and molecular comparisons were carried out to investigate whether these two taxa are conspecific. Morphological analyses showed no significant difference between specimens identified as N. wearnei and N. californicus. Similarly, genetic distances between these taxa were null, showing that all these specimens belong to the same species. Although it is not yet possible to conclude that all the specimens identified as N. wearnei are N. californicus, we can conclude that N. californicus is present in Australia. The information about the biology of N. californicus can thus now be applied to the Australian population of this species for biological control purposes.
植绥螨科的物种被称为捕食螨，其中一些在世界各地的农作物中用于控制螨类害虫。加州新小绥螨（=加州盲走螨）是生物防治项目中最常用的植绥螨科物种之一，尤其是在葡萄园、果园和蔬菜地。该物种分布于全球，但从未在澳大利亚被报道过。另一方面，形态上与加州新小绥螨相近的标本被归为一个名为韦氏新小绥螨的物种，仅在澳大利亚被报道过。基于形态学和分子比较进行了调查，以研究这两个分类单元是否为同种。形态学分析表明，被鉴定为韦氏新小绥螨和加州新小绥螨的标本之间没有显著差异。同样，这些分类单元之间的遗传距离为零，表明所有这些标本都属于同一物种。虽然目前还不能得出所有被鉴定为韦氏新小绥螨的标本都是加州新小绥螨的结论，但我们可以得出加州新小绥螨存在于澳大利亚的结论。因此，关于加州新小绥螨生物学的信息现在可以应用于该物种在澳大利亚的种群，用于生物防治目的。
