Reliable distribution maps are in the basis of insect conservation, but detailed chorological information is lacking for many insects of conservation concern (the Wallacean shortfall). Museum collections, entomological publications and citizen science projects can contribute to solve this Wallacean shortfall. Their relative contribution to the knowledge on the distribution of threatened insects has been scarcely explored, but it is important given that each of these three sources of information has its own biases and costs. Here we explore the contribution of museum data, entomological publications and citizen science in delineating the distribution of the European stag beetle in Spain. Citizen science contributed the highest number of records and grid cells occupied, as well as the highest number of grid cells not contributed by any other information source (unique grid cells). Nevertheless, both museum data and publications contributed almost 25% of all unique grid cells. Furthermore, the relative contribution of each source of information differed in importance among Spanish provinces. Given the pros and cons of museum data, publications and citizen science, we advise their combined use in cases, such as the European stag beetle in Spain, in which a broad, heterogeneous, sparsely populated territory has to be prospected.
可靠的分布图是昆虫保护工作的基础，但许多受保护关注的昆虫缺乏详细的分布信息（华莱士缺口）。博物馆馆藏、昆虫学出版物和公民科学项目有助于解决这一华莱士缺口。它们对濒危昆虫分布知识的相对贡献鲜有研究，但鉴于这三种信息来源都有各自的偏差和成本，这一点很重要。在此，我们探讨博物馆数据、昆虫学出版物和公民科学在描绘西班牙欧洲锹甲分布方面的贡献。公民科学贡献的记录数量和占据的网格单元数量最多，以及未被任何其他信息来源贡献的网格单元数量（独特网格单元）最多。然而，博物馆数据和出版物贡献了几乎所有独特网格单元的25%。此外，每种信息来源的相对贡献在西班牙各省的重要性有所不同。鉴于博物馆数据、出版物和公民科学的优缺点，我们建议在诸如西班牙欧洲锹甲这类需要勘查广阔、多样且人口稀少地区的情况下，将它们结合使用。
