Three new species of Leptoceridae were described from the Lower Mekong tributaries, namely Ceraclea luangnamthaensis n. sp., Setodes xangthevadaensis n. sp. from Laos, and Setodes mongkondechsawati n. sp. from Cambodia. The male genitalia of Ceraclea luangnamthaensis n. sp. are distinguished from those of other species by its preanal appendages, which are circular in lateral view. The male genitalia of Setodes xangthevadaensis n. sp. are distinguished from those of other species by their segment X, which is separated into a trifurcate apicodorsal process and two long slender apicolateral processes in dorsal view. The male genitalia of Setodes mongkondechsawati n. sp. are distinguished from those of other species by the apicodorsal process of segment X which is circular in dorsal view.
从湄公河下游支流描述了3种新的细角蜉科物种，即来自老挝的琅南塔角蜉Ceraclea luangnamthaensis新种、桑泰瓦达细蜉Setodes xangthevadaensis新种，以及来自柬埔寨的蒙空德查瓦蒂细蜉Setodes mongkondechsawati新种。琅南塔角蜉Ceraclea luangnamthaensis新种的雄性生殖器与其他物种的区别在于其肛前附器，从侧面看呈圆形。桑泰瓦达细蜉Setodes xangthevadaensis新种的雄性生殖器与其他物种的区别在于其第X节，从背面看，该节分为一个三叉状的背顶端突和两个细长的侧顶端突。蒙空德查瓦蒂细蜉Setodes mongkondechsawati新种的雄性生殖器与其他物种的区别在于第X节的背顶端突，从背面看呈圆形。
