NEW SPECIES OF PRODISTOMUM LINTON, 1910 (DIGENEA: LEPOCREADIIDAE) FROM THE LONGTAIL BASS, HEMANTHIAS
June 27th, 2008 | by admin |NEW SPECIES OF PRODISTOMUM LINTON, 1910 (DIGENEA: LEPOCREADIIDAE) FROM THE LONGTAIL BASS, HEMANTHIAS LEPTUS (GINSBURG, 1952), FROM THE BAY OF CAMPECHE IN THE GULF OF MEXICO.
Prodistomum lichtenfelsi n. sp. (Digenea: Lepocreadiidae) is described from the intestine of the longtail bass, Hemanthias leptus (Ginsburg), collected from the Bay of Campeche in the Gulf of Mexico. This is the first record of a parasite from this host. Prodistomum lichtenfelsi n. sp. is similar to P. hynnodi, P. menidiae, and P. waltairensis in that it possesses a prepharynx that is distinctly shorter (153 [110-210] long) than the combined length of the esophagus (163 [110-220] long) and the pseudo-esophagus (137 [120-170] long), but it differs from them in having an excretory vesicle that extends into the forebody, in having a smooth ovary and testes, and in having vitellaria that extend to the posterior level of the esophagus. An updated key to the 12 nominal species within Prodistomum is given, and the diagnosis of the genus is emended to include species possessing a sinuous external seminal vesicle.
