Abstract

The generic classification of Lymexylidae is reexamined, particularly with reference to the Australian fauna. The transfer of the Madagascar genus and species Alcestoma serropalpoides Fairmaire (1895) from Melandryidae to Lymexylidae, proposed by Nikitsky in Nikitsky et al. (1998), is confirmed and the genus is considered to be a senior synonym of Protomelittomma Wheeler (1986), syn. n. The occurrence of the genus Alcestoma in Australia is noted and a new species, Alcestoma queenslandicum, sp. n. is described from northern Queensland. The genus Arractocetus Kurosawa (1985) is also recorded for the first time from Australia, but the species is not described. A new genus, Leptonetron, gen. n., is described, based on the type species Atractocerus victoriensis Blackburn, 1891, which is considered to be a senior synonym of Atractocerus tasmaniensis Lea, 1917, syn. n. A key is provided for the Australian genera and species of Lymexylidae and the evolution of the family is briefly discussed.

摘要

重新审视了 Lymexylidae 的通用分类，特别是参考了澳大利亚动物群。Nikitsky 等人（1998 年）提议将马达加斯加属和种 Alcestoma serropalpoides Fairmaire（1895 年）从 Melandryidae 转移到 Lymexylidae，这一观点得到了确认，该属被认为是 Protomelittomma Wheeler（1986 年）的高级同义词，即 syn. n. 注意到澳大利亚存在 Alcestoma 属，并描述了来自昆士兰州北部的新种 Alcestoma queenslandicum，sp. n. 。Arractocetus Kurosawa（1985 年）也首次被记录在澳大利亚，但该物种未被描述。基于 Atractocerus victoriensis Blackburn，1891 这一模式种，描述了一个新属 Leptonetron，gen. n. ，被认为是 Atractocerus tasmaniensis Lea，1917 的高级同义词，即 syn. n. 提供了澳大利亚 Lymexylidae 属和种的关键，并简要讨论了该科的进化。
