The Simulium rufibasis subgroup is one of three subgroups of the Simulium (Simulium) tuberosum species-group; it is characterized by a pair of clustered stout hairs on the ventral surface of female abdominal segment 7. A member of the S. rufibasis subgroup in Taiwan was investigated morphologically and genetically using the universal cytochrome c oxidase subunit I (COI) barcoding gene and polytene chromosomal banding pattern. The Taiwanese material is morphologically similar to S. rosliramlii Takaoka & Chen from Vietnam and represents the second species of the S. rufibasis subgroup known from Taiwan. It also represents a novel molecular lineage that is distinct from three other primary lineages identified as S. doipuiense, S. doipuiense/S. rufibasis, and S. weji previously reported from Thailand. The mitochondrial evidence for a distinct lineage in Taiwan is supported by chromosomal analysis, which revealed unique sex chromosomes. For nomenclatural stability, we associate the name S. arisanum Shiraki with the Taiwanese entity. Originally described from females from Taiwan, S. arisanum until now has remained an enigmatic species.
红基蚋亚组是瘤蚋种组的三个亚组之一；其特征是雌虫腹部第7节腹面有一对簇生的粗壮刚毛。利用通用细胞色素c氧化酶亚基I（COI）条形码基因和多线染色体带型，对台湾红基蚋亚组的一个成员进行了形态学和遗传学研究。台湾的该材料在形态上与越南的罗氏蚋相似，是台湾已知的红基蚋亚组的第二个物种。它还代表了一个新的分子谱系，与之前在泰国报道的另外三个主要谱系不同，这三个谱系分别被鉴定为多普蚋、多普蚋/红基蚋和韦吉蚋。台湾存在独特谱系的线粒体证据得到了染色体分析的支持，染色体分析揭示了独特的性染色体。为了命名的稳定性，我们将阿里山蚋这个名称与台湾的这个实体联系起来。阿里山蚋最初是根据台湾的雌虫描述的，至今仍是一个神秘的物种。
