untangling convoluted taxonomy of chambriella rego, chubb & pavanelli, 1999 (cestoda: proteocephalidae), with erection of riggenbachiella n. g. and the description of a new species from pimelodid catfishes in the neotropical part of a complex revision of proteocephalid cestodes parasitic in freshwater bony fishes of the neotropical region, the genus chambriella rego, chubb & pavanelli, 1999 is redefined based on detailed examination of type-specimens and newly collected material of both nominal species of the genus. this examination revealed that the type-species c. agostinhoi (pavanelli & santos, 1992) from zungaro jahu (ihering) (type-host) and z. zungaro (humboldt) is indistinguishable from lenhataenia megacep ...201728220284

(proteocephalidae: proteocephalinae), which was found in the intestine of pseudoplatystoma reticulatum (eigenmann et eigenmann) from the colastiné river, a tributary of the paraná river. the new species differs from the two other species of the genus, p. eirasi (rego et de chambrier, 1995) and p. ludovici ruedi et de chambrier, 2012, parasites of phractocephalus hemioliopterus (bloch et schneider) from the ...201425549501
