The description of the sp. has been ongoing since first described and especially within the last fifteen years. Recently from the known species, three subspecies have been recognized at the species level. Two of these species, and , have been geographically described throughout Australia; however, the northeast Queensland labeled remain unrevised. A third species, , is located throughout New Guinea and is associated with at least one divergence event to Australia. Our research used geometric morphometrics and linear measurements to compare known Australian species with specimens from Cape York and New Guinea. No significant shape difference was found between the known specimens of and Cape York specimens. Our findings support an earlier identification of at this location. Significant shape variation was found between Cape York specimens and New Guinea, indicating no association with the New Guinea species. Significant shape changes were also found in island specimens when compared with the mainland New Guinea specimens, which was likely a result of their isolation and accelerated evolutionary responses to novel environments. No significant shape change was found for mainland New Guinea specimens, which was likely associated with overlapping distribution and hybridization.
自首次描述该物种以来，对其的描述工作一直在进行，尤其是在过去的十五年里。最近，从已知物种中，在物种层面上已识别出三个亚种。其中两个物种， 和 ，在澳大利亚各地都有地理描述；然而，标注为 的昆士兰东北部地区仍未修订。第三个物种， ，分布于新几内亚各地，并且与至少一次向澳大利亚的分化事件有关。我们的研究使用几何形态测量学和线性测量方法，将已知的澳大利亚物种与来自约克角和新几内亚的标本进行比较。在 和约克角标本的已知标本之间未发现显著的形状差异。我们的研究结果支持在此位置对 的早期鉴定。在约克角标本和新几内亚标本之间发现了显著的形状变异，表明与新几内亚物种没有关联。与新几内亚大陆标本相比，在岛屿标本中也发现了显著的形状变化，这可能是它们隔离以及对新环境加速进化反应的结果。新几内亚大陆标本未发现显著的形状变化，这可能与分布重叠和杂交有关。
