This study enhances knowledge of black fly biodiversity in Cameroon by integrating morphological and molecular analyses. A total of 19 species were identified from 1184 pupae collected across 13 sites, using morphological examination of gills and DNA sequencing of Cox1 and ITS2 markers. Key findings include the first report of 2 not yet described (based on identification keys used) species in Cameroon and confirmation of and as known vectors of onchocerciasis. DNA sequences have been deposited in GenBank for reference.
Combining morphological and molecular approaches revealed more species diversity than previously described, showing the potential of molecular techniques in black fly study. Notably, the presence of species not typically associated with human-biting behavior (e.g., ) raises the possibility that such flies could act as vectors under favorable conditions.
This study underscores the importance of identifying species for understanding their role in pathogen transmission. The results provide a foundation for further research on undescribed species and their potential vectorial capacities. Future studies should explore the ecological and behavioral factors influencing vector status, especially in the context of environmental changes. By bridging morphology and DNA analysis, this research advances the study of black flies and sets the stage for improved vector monitoring and disease control in Cameroon and beyond.
本研究通过整合形态学和分子分析，增进了对喀麦隆蚋类生物多样性的了解。通过对鳃的形态学检查以及对Cox1和ITS2标记进行DNA测序，从13个地点收集的1184个蛹中总共鉴定出19种。主要发现包括喀麦隆首次报告2个尚未描述的（基于所使用的鉴定关键特征）物种，以及确认*[此处原文可能遗漏具体物种名称]**为已知的盘尾丝虫病传播媒介。DNA序列已存入GenBank以供参考。
形态学和分子方法相结合揭示出比先前描述的更多的物种多样性，显示出分子技术在蚋类研究中的潜力。值得注意的是，存在一些通常与人类叮咬行为无关的物种（例如*[此处原文可能遗漏具体物种名称]*），这增加了此类苍蝇在有利条件下可能充当传播媒介的可能性。
本研究强调了鉴定蚋类物种对于了解它们在病原体传播中作用的重要性。研究结果为进一步研究未描述的蚋类物种及其潜在传播能力提供了基础。未来的研究应探索影响传播媒介地位的生态和行为因素，特别是在环境变化的背景下。通过将形态学与DNA分析相结合，本研究推动了蚋类研究的进展，并为喀麦隆及其他地区改善传播媒介监测和疾病控制奠定了基础。
