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 monorchiid genera with diagonal or tandem testes by the following combination of characteristics: vitellaria in 2 lateral groups of pre- and 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. KEY WORDS: digenetic trematodes, Monorchiidae, Proctotrematoides, Opisthodiplomonorchis, Zhukovtrema, marine fishes, Synaptura orientalis, Pseiidorhombus arsius, Polydactylus sextarius, Plectorhynchus sp., Arabian Gulf, Kuwait. During the course of a survey of helminth 1801) (Polynemidae), and 4 of an unidentified grunt, parasites of Kuwaiti coast fishes carried out by Plectorhynchus sp. (family Pomadasydae), obtained from the local fish market, were examined and found the first author between October 1992 and De- to harbor monorchiids. The digeneans were washed in cember 1995, a collection of digenetic trema- saline, fixed in cold AFA under slight coverglass pres- todes was obtained that included several species sure, rinsed in 70% ethanol, stained with alum car- of monorchiids, 2 of which are described in this mine, destained in diluted HC1, dehydrated in ascend- ing concentrations of ethanol, cleared in clove oil, and paper. Four previous reports on adult digenea mounted in Canada balsam. from the Kuwaiti coast have been published (see All measurements are expressed in micrometers, Al-Yamani and Nahhas, 1981; Abdul-Salam and with the range followed by measurements of the ho- Khalil, 1987; Abdul-Salam et al., 1990; Abdul- lotype in parentheses. Sucker ratio was calculated from Salam and Sreelatha, 1993). No monorchiids the mean of the length and the width and is expressed with the oral sucker taken as 1. Drawings of the adult were reported in any of these studies. Monor- worms were prepared by microprojection and details chiids have been recorded, however, from fishes filled in through microscopic observations; those of the of other parts of the Arabian Gulf.
