In a world where insects and notably bees are declining, assessing their distribution over time and space is crucial to evaluate species status and highlight conservation priorities. However, this can be a daunting task, especially in areas such as tropical oceanic islands where exhaustive samplings over time have been lacking. This is the case in New Caledonia, an archipelago located in the southwest Pacific. Historical records of bee species are piecemeal and, although contemporary samplings have significantly advanced our knowledge of the bee fauna of New Caledonia, the status of several species remains to be elucidated.
Here, we provide an updated checklist of the 51 bee species recorded for New Caledonia using previous publications and personal samplings. We documented their distribution, origin (i.e. endemic, native or alien) and the year and location of their occurrences. Based on the year of their first capture and the year of their last capture, we determined an occurrence status for each species. Thus, 10 years after the last checklist of the New Caledonian bee fauna, the literature review and recent samplings allowed us to add six new species to the list. Half of them are recently introduced species including one firstly mentioned in this paper (i.e. ). We consider here that 30 species are effectively present on the territory and the presence of 21 species could not be determined due to a lack of data, which highlights the need to increase sampling efforts across New Caledonia. Given the difficulty of exhaustively sampling the entire archipelago, we would recommend taking, as a starting point, altitude environments and areas where data-deficient species were captured. In a broader perspective, biomolecular analyses are crucial to confirm species identifications. This is also needed to make comparisons between archipelagoes and thus clarify the distribution and status of species at the scale of the southwest Pacific.
在昆虫尤其是蜜蜂数量不断减少的世界里，评估它们在时间和空间上的分布对于评估物种状况和突出保护重点至关重要。然而，这可能是一项艰巨的任务，特别是在热带海洋岛屿等长期缺乏详尽采样的地区。新喀里多尼亚就是这样一个位于西南太平洋的群岛。蜜蜂物种的历史记录是零散的，尽管当代采样极大地增进了我们对新喀里多尼亚蜜蜂动物群的了解，但仍有几种物种的状况有待阐明。
在此，我们利用先前的出版物和个人采样，提供了一份新喀里多尼亚记录的51种蜜蜂的更新清单。我们记录了它们的分布、起源（即特有、本土或外来）以及出现的年份和地点。根据首次捕获年份和最后捕获年份，我们确定了每个物种的出现状况。因此，在新喀里多尼亚蜜蜂动物群的上一份清单发布10年后，文献综述和近期采样使我们能够在清单中新增6个物种。其中一半是最近引入的物种，包括本文首次提及的一个物种（即 ）。我们认为该地区实际存在30个物种，由于缺乏数据，21个物种的存在无法确定，这凸显了在新喀里多尼亚增加采样工作的必要性。鉴于对整个群岛进行详尽采样存在困难，我们建议以海拔环境和捕获数据不足物种的区域为起点。从更广泛的角度来看，生物分子分析对于确认物种鉴定至关重要。在各群岛之间进行比较从而阐明西南太平洋范围内物种的分布和状况也需要这种分析。
