Geospatial coordinate data for 125 species of New South Wales Drosophilidae (Diptera)

Label data from specimens in the Australian Museum (Sydney), and the Australian National Insect Collection (CSIRO, Canberra) have been compiled. Abundance data is excluded. Only those species collected within the mainland part of the geopolitical boundary of the Australian state of New South Wales are included; Norfolk Island and Lord Howe Island (McEvey, 2017) are excluded. To this dataset has been added distribution records from the literature, mainly works by Bock and Parsons (1970s and 1980s) and McEvey (1994, 2020) and from the shared datasets of colleagues Dr Michele Schiffer (<i>Drosophila serrata</i>; SourceNote = 3) and Prof. J.S.F. Barker (species associated with <i>Opuntia</i> cactus; SourceNote = 1). Coordinate accuracy is indicated as follows: a specimen of a species reported from the Blue Mountains, for example, without any other geospatial information, has very low “Coordinate Precision” indicated as ±100km (Precision 5); whereas a specimen collected at a high-accuracy GPS waypoint has very high “Coordinate Precision” indicated as ±10m to ±100m (Precision 1 to 2); a Precision 2 coordinate may lie within the range of a Precision 5-rated coordinate (for example Mount Wilson within the Blue Mountains). The taxonomy of a small number of species is problematic, in particular, uncertainty currently surrounds <i>Drosophila repleta </i>(SourceNote = 2), <i>Scaptodrosophila notha</i> and <i>S. specensis </i>(SourceNote = 4) (McEvey, unpubl.). As indicated by McEvey (1994, 2020), many of the 125 species known from NSW have distributions that extend beyond the political border, especially northwards into the Australian state of Queensland.

本数据集整合了澳大利亚博物馆（悉尼）及澳大利亚国家昆虫标本馆（澳大利亚联邦科学与工业研究组织，CSIRO，堪培拉）馆藏标本的标签数据，并排除了丰度数据。本数据集仅收录采集于澳大利亚新南威尔士州政治管辖范围内陆地区域的物种标本，排除诺福克岛与豪勋爵岛相关记录（McEvey, 2017）。此外，本数据集还补充了来自文献的分布记录，主要包括Bock与Parsons在20世纪70、80年代的研究成果，以及McEvey（1994、2020）的相关文献；同时纳入了同事米歇尔·希弗博士（共享数据集涉及<i>Drosophila serrata</i>，来源标注=3）与J.S.F.巴克教授（共享数据集涉及与梨果仙人掌<i>Opuntia</i>共生的物种，来源标注=1）提供的共享数据集。坐标准确性标注规则如下：例如，若某物种标本仅标注采集地为蓝山，未附带其他地理空间信息，则其"坐标精度（Coordinate Precision）"极低，标注为±100公里（精度等级5）；若标本通过高精度GPS航点采集，则其"坐标精度（Coordinate Precision）"极高，标注为±10米至±100米（精度等级1至2）；精度等级2的坐标可能落在精度等级5的坐标范围内，例如蓝山区域的威尔逊山。部分物种的分类学地位尚存争议，目前尤其不确定的类群包括<i>Drosophila repleta</i>（来源标注=2）、<i>Scaptodrosophila notha</i>及<i>S. specensis</i>（来源标注=4）（McEvey，未发表）。正如McEvey（1994、2020）所言，目前在新南威尔士州记录到的125个物种中，多数类群的分布范围已超出该州政治边界，尤其是向北延伸至澳大利亚昆士兰州境内。
