【目的】羽祝蛾属是昆虫纲鳞翅目祝蛾科的重要类群之一。本研究旨在阐述该类群昆虫地理分布现状及其在中国的适生范围。【方法】通过收集整理该属昆虫已发表资料，对羽祝蛾属物种世界地理分布进行了直观性标注。同时，采用最大熵模型对其进行了适生区预测及区域划分。【结果】羽祝蛾属昆虫世界已知22种，中国记录17种，泰国记录2种，斯里兰卡、印度、日本、越南各记录1种。在我国主要分布在以长江为界的南方地区；物种多样性总体呈现出由北向南递增的趋势。适生区预测结果表明：其适生区域主要集中在18°N~32°N之间，高适宜生境主要集中于我国横断山脉以东、长江中下游以南地区；昼夜温差月均值与降雨量是影响羽祝蛾属适生分布的主要因素。【结论】羽祝蛾属昆虫主要在我国分布且集中于南方地区。研究结果有助于揭示该类群的地理分布面貌，增加对该类群的广泛认识。

英文摘要:

【Aim】Nosphistica is one of the important genera of the family Lecithoceridae (order Lepidoptera, class Insecta). This study aims to clarify the current geographical distribution of this genus and its suitable habitat range in China. 【Methods】Based on published data of Nosphistica, the global geographical distribution of its species was visually mapped. Meanwhile, the Maximum Entropy (MaxEnt) model was employed to predict and zone its suitable habitats. 【Results】A total of 22 Nosphistica species are known worldwide, 17 of which are recorded in China, 2 in Thailand, and 1 each in Sri Lanka, India, Japan, and Vietnam. In China, the genus is mainly distributed in southern regions, broadly demarcated by the Yangtze River, with species diversity generally exhibiting an increasing trend from north to south. Prediction results of suitable areas indicate that the suitable areas are mainly concentrated between 18°N and 32°N, and the high habitat suitability areas are primarily located east of the Hengduan Mountains and south of the middle and lower reaches of the Yangtze River in China. The monthly mean diurnal temperature range and precipitation are the main factors affecting the suitable distribution of Nosphistica. 【Conclusion】Nosphistica is mainly distributed in China and concentrated in southern regions. This study's results contribute to revealing the geographical distribution pattern of this genus and enhancing broader understanding of it.
