Abstract

A new species of Heptageniidae, , is described based on larvae, subimagos, eggs, and COI data. The mayfly genus Eaton, 1881 is reported for the first time from Thailand. The larva of the new species can be distinguished from other known species by i) lamellae of gill I ca 1/4 of fibrilliform portion and ii) mandibles and basal segment of maxillary palp without dense setae on margin. The subimago characters useful to distinguish this new species from previously known species are i) the median stripes on abdominal terga and ii) shape of the female subgenital and subanal plates. The genetic distance between the new species and (Eaton, 1871) was approximately 11%. The morphological characters of the new species are discussed and compared to other known species.

摘要

基于幼虫、亚成虫、卵和细胞色素氧化酶亚基I（COI）数据，描述了扁蜉科的一个新物种。1881年的伊顿蜉蝣属首次在泰国被报道。新物种的幼虫可通过以下特征与其他已知物种区分开来：i）第一鳃片约为丝状部分的1/4；ii）上颚和下颚须基部节边缘无密集刚毛。有助于将该新物种与先前已知物种区分开来的亚成虫特征为：i）腹部背板上的中条纹；ii）雌性亚生殖板和亚肛板的形状。新物种与（伊顿，1871年）之间的遗传距离约为11%。讨论了新物种的形态特征，并与其他已知物种进行了比较。
