Males and very tiny nongravid female philometrid nematodes were collected from the ovaries of the fish. Based on light and scanning electron microscope observations, and supported by molecular analyses of the partial nucleotide sequences of the 18S small subunit ribosomal DNA, the philometrid nematode was determined to be a new species belonging to the genus Philometra Costa, 1845 in the family Philometridae (Nematoda: Dracunculoidea), and was named P. philippinensis sp. nov. This new species was clearly distinguishable morphologically from other congeners that parasitize the gonads of marine fishes. Males have unique sickle-shaped spicules and gubernaculum, and a vulva-like cloacal opening. Following Dentirumai philippinensis Quiazon et Moravec, 2013 and Philometra robusta Moravec, M\u00f6ller et Heeger, 1992, this is the third philometrid species and the first gonad-infecting philometrid from the Philippine archipelago.<\/jats:p>","DOI":"10.2478\/s11686-013-0165-3","type":"journal-article","created":{"date-parts":[[2013,12,12]],"date-time":"2013-12-12T09:21:47Z","timestamp":1386840107000},"source":"Crossref","is-referenced-by-count":7,"title":["Gonad-infecting philometrid Philometra philippinensis sp. nov.
