The superfamily Psylloidea includes numerous species which play a key role in Australian ecology and biodiversity, as well as pests and biological control agents, and sometimes threatened species of conservation concern. Different psyllid sampling and collection techniques are usually performed depending on the nature and aim of the study: from the beating and sweeping of psyllid host plants for conservation and biodiversity assessment, to suction and sticky traps in agriculture. Due to a general lack of information on its efficacy for psyllids, however, light trapping has not usually been employed. Here we present the results obtained trapping psyllids using different light sources and we discuss the strengths and weaknesses of this technique to assess psyllid biodiversity. In particular, we highlight the strength of using this methodology paired with DNA barcoding, to cast some light on psyllid biodiversity. The results obtained here suggest that the psyllid fauna of Australia is heavily understudied and the number of undescribed species might be many times higher than previously expected. Additionally, we report, for the first time, the species Trioza adventicia Tuthill 1952, and Cryptoneossa triangula Taylor 1990 in the state of Queensland.

利用光诱捕方法收集对澳大利亚木虱（半翅目：Psylloidea）的生物多样性的见解。

蕨类超科包括众多在澳大利亚生态和生物多样性中发挥关键作用的物种，以及害虫和生物防治剂，有时甚至是受到保护的濒危物种。通常根据研究的性质和目的执行不同的木虱取样和收集技术：从木虱寄主的打打和清扫以进行保护和生物多样性评估，到农业中的吸粘陷阱。然而，由于普遍缺乏关于其对木虱的功效的信息，因此通常不采用光捕获。在这里，我们介绍了使用不同光源捕获木虱的结果，并讨论了该技术评估木虱生物多样性的优缺点。尤其是，我们强调了将这种方法与DNA条形码搭配使用的优势，可以为木虱生物多样性提供一些启示。此处获得的结果表明，澳大利亚的木耳动物区系研究严重不足，未描述物种的数量可能比以前的预期高出许多倍。此外，我们首次报告了该物种Trioza adventicia Tuthill（1952年）和Cryptoneossa triangula Taylor（1990年）在昆士兰州。
