The Schultzei group of Culicoides Latreille (Diptera: Ceratopogonidae) is distributed throughout Africa to northern Asia and Australasia and includes several potential vector species of livestock pathogens. The taxonomy of the species belonging to this species group is confounded by the wide geographical distribution and morphological variation exhibited by many species. In this work, morphological and molecular approaches were combined to assess the taxonomic validity of the species and morphological variants of the Schultzei group found in Senegal by comparing their genetic diversity with that of specimens from other geographical regions. The species list for Senegal was updated with four species: Culicoides kingi, C. oxystoma, C. enderleini and C. nevilli being recorded. This is the first record of C. oxystoma from Africa south of Sahara, and its genetic relationship with samples from Israel, Japan and Australia is presented. This work provides a basis for ecological studies of the seasonal and spatial dynamics of species of this species group that will contribute to better understanding of the epidemiology of the viruses they transmit.
舒尔采氏库蠓属（蚊科：蠓科）分布于非洲北部至亚洲和澳大拉西亚地区，包括几种潜在的牲畜病原体的媒介物种。由于许多物种的地理分布广泛和形态变异，该物种组的物种的分类学存在混淆。在这项工作中，通过比较形态和分子方法，结合了形态和分子方法来评估塞内加尔舒尔采氏库蠓属物种和形态变体的分类学有效性，以及它们与来自其他地理区域的标本的遗传多样性。塞内加尔的物种名录更新了四种物种：记录了库蠓金氏亚种、C. oxystoma、C. enderleini 和 C. nevilli。这是撒哈拉以南非洲首次记录到 C. oxystoma，同时介绍了它与来自以色列、日本和澳大利亚的样本的遗传关系。这项工作为研究该物种组的季节性和空间动态的生态学研究提供了基础，这将有助于更好地了解它们传播的病毒的流行病学。
