Phyllodiaptomus (Phyllodiaptomus) roietensis was collected from temporary water bodies in Roi Et and Nakhon Ratchasima provinces in northeastern Thailand and Kampong Thom Province in central Cambodia. The new species is closely related to Phyllodiaptomus (P.) surinensis Sanoamuang & Yindee, 2001 in that it shares common morphological characters in the males: urosomites 2-3, P5 intercoxal sclerite, right P5 Exp-2, and left P5 Exp. Minor differences on the right antennule, right caudal ramus, P5 basis and Enp exist. The females differ in their Pdg 5, genital double-somite, and P5. An updated key to the species of the genus Kiefer, 1936 is provided.

罗氏叶镖水蚤（Phyllodiaptomus (Phyllodiaptomus) roietensis）采自泰国东北部黎逸府和呵叻府以及柬埔寨中部磅通省的临时性水体。该新物种与2001年发现的苏氏叶镖水蚤（Phyllodiaptomus (P.) surinensis Sanoamuang & Yindee）密切相关，因为其雄性具有共同的形态特征：尾节2 - 3、第五胸足基节间骨片、右第五胸足外肢第二节和左第五胸足外肢。在右触角、右尾叉、第五胸足基部和内肢上存在细微差异。雌性在第五胸足后侧刚毛、生殖双节和第五胸足方面存在差异。提供了1936年 Kiefer属物种的最新检索表。
