Abstract

Two new species of Acanthocyrtus Handschin from Western Australia are described and illustrated here. Acanthocyrtus necropolitanus sp. nov. and A. pallidus sp. nov. resemble other congenerics by having smooth prelabral chaetae and a unique dorsal chaetotaxy pattern from the third thoracic segment to the third abdominal segment, but both new species are distinguished from others by the presence of labral papillae, a feature is revealed here for the first time in the genus. An identification key for all species in the genus is provided. The description of these two Acanthocyrtus species now increased from six to eight and is now known from southwestern Australia.

摘要

这里描述并图示了来自澳大利亚西部的两种新的棘胸蛙属（Acanthocyrtus）物种。新种 Acanthocyrtus necropolitanus 和 A. pallidus 与其他同属物种相似，具有光滑的前唇乳突和从第三胸节到第三腹节独特的背部分化模式，但这两个新种都与其他物种区分开来，因为它们具有唇乳突，这是该属中首次发现的特征。提供了属内所有物种的鉴定钥匙。现在，这两个棘胸蛙属物种的描述从六个增加到八个，并且现在已知来自澳大利亚西南部。
