Abstract

The genus Ephoron Williamson, 1802 is widely distributed around the world. In Thailand, only Ephoron indicus Pictet, 1843 was reported in 1961. In this study, a new Ephoron mayfly is described as Ephoron ookaewae sp. nov. In this new species description, the morphological characteristics of larvae and eggs in addition to adults are also shown in detail. Number of tubercles on mandibular tusks, and a median frontal process in larvae, distinguish Ephoron ookaewae sp. nov. from other Ephoron species. Their polar cap shape and a concave indentation in their eggs are also unusual. In addition, the mitochondrial DNA COI sequence data of the newly described Ephoron ookaewae sp. nov. is registered in GenBank. Registration of sequence data for the DNA barcode region of Ephoron mayflies inhabiting the Oriental region remains limited, however it will be useful for future research.

摘要

属 Ephoron Williamson，1802 广泛分布于世界各地。在泰国，1961 年只报道了 Ephoron indicus Pictet，1843。在本研究中，描述了一种新的 Eophron 蜉蝣，命名为 Ephoron ookaewae sp. nov.。在这个新物种描述中，幼虫和卵的形态特征以及成虫的形态特征都详细展示。幼虫的下颌獠牙上的瘤数，以及额中突，将 Ephoron ookaewae sp. nov. 与其他 Ephoron 物种区分开来。它们的极帽形状和卵上的凹陷也不寻常。此外，新描述的 Ephoron ookaewae sp. nov. 的线粒体 DNA COI 序列数据已在 GenBank 中注册。然而，东方地区栖息的 Ephoron 蜉蝣 DNA 条形码区域的序列数据的注册仍然有限，这将对未来的研究很有用。
