Abstract: Two species of monorchiids are described from marine fishes of the Kuwaiti coast of the Arabian Gulf: Proctotrematoides kuwaiti sp. n. from Synaptura orientalis and Pseudorhombus arsius differs from all others in the genus by the absenc e of a prepharynx and esophagu s and by the arrangemen t and position of the vitelline follicles. Opisthodiplomonorchis elongatus Madhavi, 1974, is reported from Polydactylus sextarius and Plectorhynchus sp., both new locality records and the latter a new host record. Opisthodiplomonorchis differs from all monorchii d gener a with diagonal or tandem testes by the following combination of characteristics : vitellaria in 2 lateral groups of preand postovarian follicles, multilobed ovary, tandem testes at the posterior extremity, and unipartite seminal vesicle and terminal organ. Keys to the species of Proctotrematoides and monorchiids with 2 testes are included. Pseudomonorcheid.es Zhukov, 1983, nee Pseudomonorcheides Wang, 1982, is renamed Zlmkovtrema.
