| morphological and molecular analyses of the genera peltidocotyle diesing 1850 and othinoscolex woodland 1933, and a morphological study of woodlandiella freze, 1965 (eucestoda, proteocephalidea), parasites of south american siluriform fishes (pimelodidae). | morphological studies of type-species of the genera peltidocotyle diesing, 1850 and othinoscolex woodland, 1933 showed that these genera are synonyms. we therefore redescribe the type and fresh material of peltidocotyle rugosa diesing, 1850 and p. lenha (woodland, 1933) [= othinoscolex lenha woodland, 1933], which appears to constitute two distinct species. they differ in the number and number of layers of testes, the diameter of the metascolex and the field occupied by the vitelline follicles. ... | 2000 | 10803434 |
