| morphology of the advanced-stage larva of eustrongylides wenrichi canavan 1929, occurring encapsulated in the tissues of amphiuma in louisiana. | larval nematodes identified as eustrongylides wenrichi canavan 1929, from cysts in the tissues of amphiuma means tridactylum cuvier in louisana were redescribed. the extent of differentiation of the sex organs was found to be greater than that of 3rd-stage dioctophyma renale, or of the infective stage of trichinella spiralis, and comparable with the late 4th-stage larva of secernentean (phasmid) nematodes. | 1979 | 448605 |
