| new genus with two new species of capsalid monogeneans from dasyatids in the gulf of california. | we propose listrocephalos n. gen. (monogenea: capsalidae: entobdellinae) for 2 new capsalid species that infect the skin of 2 species of diamond stingrays (dasyatidae) in the gulf of california. we also provide additional observations on 2 previously described capsalid species, which infect the external body surface of stingrays and are currently in entobdella blainville in lamarck, 1818, and transfer them to the proposed new genus. the members of this genus, listrocephalos corona (hargis, 1955) ... | 2004 | 15715238 |
| molecular identification of larvae of a tetraphyllidean tapeworm (platyhelminthes: eucestoda) in a razor clam as an alternative intermediate host in the life cycle of acanthobothrium brevissime. | dwarf razor clams (ensis minor) in the gulf of mexico are known to be infected with plerocercoid larvae of a tetraphyllidean tapeworm. here, we show that these larvae live unencysted in the intestinal lumen of the clam. morphologically, the larvae are similar to (although significantly larger than) tapeworm larvae previously described living in the gut of amphioxus (branchiostoma floridae) from the same habitat. sequence data from the d2 region of the 28s rdna from clam-infecting larvae were ide ... | 2009 | 19366282 |
