Abstract

Helix porteri Cox, 1866 is the type species of Austrochloritis Pilsbry, 1891, a speciose genus of camaenid land snail with a known range in eastern Australia stretching from Wilson’s Promontory in Victoria to southeastern Queensland. This species was first described based on material from two locations in New South Wales, “Upper Clarence River at Guy Faux Station” and “Upper Richmond River, at Cowlong”. These two locations are about 230 km apart from each other while all type material is considered to be lost. Comparative morpho-anatomy of specimens collected in the proximity of both type localities shows that the original concept of Helix porteri is based on two distinct species. Here we designate a neotype for this species from the Upper Richmond River area and provide a detailed redescription in order to remove any ambiguity about the identity of Austrochloritis porteri. Material from the vicinity of the second site mentioned in the original description of H. porteri, Guy Fawkes Station, is identified as Austrochloritis speculoris Shea & Griffiths, 2010. We describe key diagnostic features distinguishing both species.

对1891年东澳大利亚陆地蜗牛austrochoritis Pilsbry的系统修订:对其模式种a . porteri的重新描述(Cox, 1866)
Helix porteri Cox,1866年是Austrochloritis Pilsbry,1891年的模式种,这是一种卡马尼地蜗牛属,已知分布在澳大利亚东部,从维多利亚州的威尔逊岬一直延伸到昆士兰东南部。该物种最初是根据新南威尔士州两个地点的材料描述的,即“盖伊·福克斯车站的克拉伦斯河上游”和“考隆的里士满河上游”。这两个位置相距约230公里,而所有类型的材料都被认为是丢失的。在两个模式区附近采集的标本的比较形态解剖表明,港口Helix的原始概念是基于两个不同的物种。在这里,我们为该物种指定了一个来自里士满河上游地区的新类型,并提供了详细的重新描述,以消除关于波特澳虫身份的任何歧义。Guy Fawkes车站H.porteri的原始描述中提到的第二个站点附近的材料被确定为窥器奥氏菌Shea&Griffiths,2010年。我们描述了区分这两个物种的关键诊断特征。
