Abstract:

Six species of flukes each belonging to a different genus and family were identified in recent collections of trematodes from the common moorhen, Gallinula chloropus lozanoi Lletget, 1918 in the Philippines. Two species are described and illustrated as new namely Laterotrema (Pseudolaterotrema) robertloi n. sp. and Tanaisia (Tamerlania) lagunensis n sp from the intestine and kidneys,  respectively. Laterotrema (Pseudolaterotrema) robertloi is characterized by its microscopic size, the well-developed tubulo-saccular, transversely oriented and posteriorly directed, cirrus sac, occupying more than half of the width at the middle of the body; the marginal and more posterior location of the genital pore,  which is at the level of the acetebulum or posterior to it; the slightly lobed testes and ovary and intercostals location of the testes. Tanaisia (Tamerlania) lagunensis n. sp.  Is characterized by its tiny and narrow size, the spatulate expansion of the posterior extremity and the ovary and left testis tandem in position and whose borders are opposing to each other. Four species recovered were previously recorded in the country and these are Cyclocoelium orientale Skrjabin, 1918. Athesmia heterolecitodes (Braun, 1899) Looss, I899. Tubangorchis caintaensis (Tubangui, 1928) Skrjab1n & Petrov, 1950 and Notocotylus pacifer (Noble, 1933) Harwood 1939. The genus Laterotrema Semenov. 1927 is recorded for the first time in the Philippines. Tanaisia (tamerlania)lagunensis is the fourth species of the genus reported in the Philippines and together with Athesmia heterolecitodes constitute the first record of their presence in the endemic host, Gallinula chloropus lozanoi. A list of trematodes so far recorded from Gallinulla chloropus lozanoi. Lletget, 1918 in the Philippines is provided.
