The nemacheilid genus Seminemacheilus is revised. Six species are recognised, three of them described herein as new. All species are endemic to Central Anatolia. Seminemacheilus lendlii from the Sakarya River drainage and the endorheic Lake Aksehir and Eber basins, S. ispartensis from Lake Eğirdir basin and S. ahmeti from Sultan Sazlığı are valid species. Although Seminemacheilus lendlii and S. ispartensis have almost identical COI sequences, they are distinguished by the shape of the caudal peduncle and the presence of scales on the caudal peduncle in S. ispartensis (vs. absent in S. lendlii). Seminemacheilus attalicus, new species, from Kırkgöz drainage, is distinguished by having a slightly emarginated caudal fin, a central pore in the supratemporal canal and a marbled flank pattern. Seminemacheilus ekmekciae, new species, from Lake Tuz basin is distinguished by having a roundish caudal fin, a short post-dorsal length and large brown blotches fused into stripes on the flank. Seminemacheilus tubae, new species, from Lake Beyşehir basin, is distinguished by having a truncate caudal fin and 2-5 (6) supraorbital head pores. Seminemacheilus dursunavsari from the Göksu River drainage is not a valid name and this population is identified as S. tubae.
对条鳅属的半条鳅属进行了修订。确认了6个物种，其中3个在此描述为新物种。所有物种均为安纳托利亚中部特有。来自萨卡里亚河流域以及阿克谢希尔内流湖和埃伯盆地的伦氏半条鳅、来自埃迪尔内湖盆地的伊斯帕尔半条鳅和来自苏丹盐湖的艾哈迈德半条鳅均为有效物种。尽管伦氏半条鳅和伊斯帕尔半条鳅的细胞色素氧化酶亚基I（COI）序列几乎相同，但它们可通过尾柄形状以及伊斯帕尔半条鳅尾柄上有鳞片（而伦氏半条鳅没有）来区分。来自柯尔克戈兹排水区的新物种阿塔尔半条鳅的特征是尾鳍略呈凹形、颞上管有一个中央孔以及体侧有大理石花纹。来自图兹湖盆地的新物种埃克梅克恰半条鳅的特征是尾鳍圆形、背鳍后长度短以及体侧有融合成条纹的大褐色斑块。来自戈克苏河流域的杜尔松纳夫萨里半条鳅不是一个有效名称，该种群被鉴定为图巴半条鳅。
