The larval taxonomy of Australian stoneflies (Plecoptera) shows a large disparity in knowledge when compared to the adult taxonomy with many species having undescribed larval forms. The importance of stoneflies as an indicator group for monitoring aquatic ecosystems means knowledge of the larval taxonomy and the ability to identify species is essential. This study combined morphology and mitochondrial gene sequences to associate the adult and larval life-stages for species of Dinotoperla Tillyard. Morphological identification of adult males was recognised for 17 of the 35 Dinotoperla species and combining molecular data with morphology confirmed eight new adult-larval life stage associations. Further, molecular data supported the larval taxonomy for five morphospecies which remain unassociated. The combination of molecular and morphological methods enabled the larval morphology to be reassessed for the genus Dinotoperla and this has led to the establishment of two new genera, Odontoperla, gen. nov. and Oedemaperla, gen. nov., and the new species Dinotoperla aryballoi, sp. nov, D. tasmaniensis, sp. nov. and Oedemaperla shackletoni, sp. nov. as well as the new or updated descriptions of the larvae of 31 species and a comprehensive dichotomous key to these larvae.
与成虫分类学相比,澳大利亚石蝇(襀翅目)的幼虫分类学在认知上存在很大差异,许多物种的幼虫形态尚未得到描述。石蝇作为监测水生生态系统的指示生物群体,其重要性意味着幼虫分类学知识和物种鉴定能力至关重要。本研究结合形态学和线粒体基因序列,以关联 Dinotoperla Tillyard 物种的成虫和幼虫生活阶段。在 35 种 Dinotoperla 物种中,有 17 种成年雄性的形态鉴定得到认可,将分子数据与形态学相结合,确认了 8 种新的成虫 - 幼虫生活阶段关联。此外,分子数据支持了 5 个形态物种的幼虫分类学,这些形态物种尚未建立关联。分子和形态学方法的结合使得能够重新评估 Dinotoperla 属的幼虫形态,这导致了两个新属的建立,即 Odontoperla 属(新属)和 Oedemaperla 属(新属),以及新物种 Dinotoperla aryballoi(新物种)、D. tasmaniensis(新物种)和 Oedemaperla shackletoni(新物种),以及对 31 种幼虫的新描述或更新描述,还有这些幼虫的综合二分检索表。
