title: Trimusculotrema schwartzi n. sp. (Monogenea: Capsalidae) from the skin of the stingray Dasyatis zugei (Elasmobranchii: Dasyatidae) off Hong Kong, China.
abstract: Trimusculotrema schwartzi n. sp. (Capsalidae) is described from the skin of the stingray Dasyatis zugei (Elasmobranchii: Rajiformes: Dasyatidae) off Hong Kong, China. Only three other species have been placed in the genus Trimusculotrema: T. micracantha (Euzet & Maillard, 1967), T. leucanthemum (Euzet & Maillard, 1967), and T. uarnaki Whittington & Barton, 1990. T. schwartzi n. sp. may be differentiated from all known species of Trimusculotrema by the length of the anterior hamuli and by the absence of pigment shields over the eye-spots. Its occurrence on a stingray off China represents a northern extension of the geographical range of Trimusculotrema.
