Abstract

Apalochrini comprises nearly half of the genera of Australian Melyridae, which are all recognized by male specific characters, and are commonly found on grasses, flowers and riverside or seashore rocks. Here we describe a new genus Salsolaius gen. nov. from Lake Way of Western Australia, representing the first known genus of Australian Melyridae inhabitating in salt lakes. The new genus can be easily distinguished by asymmetrically biserrate antennae and exposed apical abdomen from above in both male and female, the former characters is firstly found in Melyridae. Consequently, Salsolaius biserratus sp. nov. was described as the type species of this genus. An updated key to genera of Australian Apalochrini is provided.

摘要

Apalochrini 包含了近一半的澳大利亚麦蛾科属，这些属都以雄性特有特征来识别，通常在草、花以及河边或海滨岩石上发现。这里我们描述了一个来自西澳大利亚州韦亚湖的新属——Salsolaius 属，这是澳大利亚麦蛾科已知的第一个栖息在盐湖中的属。这个新属可以很容易地通过触角不对称双锯齿状以及雌雄两性从上方观察到暴露的顶端腹部来区分，前者的特征在麦蛾科中是首次发现。因此，Salsolaius biserratus sp. nov. 被描述为这个属的模式种。提供了一个更新的澳大利亚 Apalochrini 属的关键特征。
