Philippe V. Alves, Alain de Chambrier, José L. Luque & Tomáš Scholz, 2017, Reappraisal of Goezeella Fuhrmann, 1916 (Cestoda: Proteocephalidae), parasites of Neotropical catfishes (Siluriformes), with description of a new species from Pimelodella cristata (Heptapteridae), Revue suisse de Zoologie 124 (2), pp. 335-350 : 348

Identification key to the species of Goezeella Fuhrmann, 1916

1A Vaginal sphincter at a distance from genital atrium; vitelline follicles ventrolateral. In auchenipterids ( Ageneiosus pardalis ) .............................................................................................................................................. G. danbrooksi

1B Vaginal sphincter near genital atrium (terminal); vitelline follicles only on ventral side of cortex, missing laterally .................................................................................................................................................................... 2

2A Much more than 200 testes per proglottid. In cetopsids ( Cetopsis ) and pimelodids ( Pinirampus ) ............. G. siluri

2B Much fewer than 200 testes per proglottid. In heptapterids ( Pimelodella cristata ) .................... G. mariae sp. nov.

ventral cortex (Arredondo & Gil de Pertierra, 2008), bears only uniloculate suckers, rather than biloculate as in species of Goezeella .

Species of Goezeella including G. mariae sp. nov. have been found in the Amazon and Orinoco River basins, whereas no published record exists from the Paraná River basin. The spectrum of definitive hosts of this genus, i.e. fishes of four siluriform families ( Auchenipteridae , Cetopsidae , Heptapteridae and Pimelodidae ) is markedly wider than typical for comparably species-rich genera of Neotropical proteocephalids, which are usually specific to only a single fish family ( Rego et al., 1999; de Chambrier et al., 2015a).
