Dollfusentisbravoae has 1617 hooks per longitudinal row on the proboscis, shorter lemnisci (2015516, n=9), testes that are shorter and not as wide (21846, n= 6 long and 13624, n= 6), and a uterine bell that is larger (32164, n= 4 long and 7833, n=4 wide). Adults of all other known species of the genus inhabit the intestine of their host, but adults of D. salgadoi n. sp.inhabit the rectum of its host
