On the monophyly of Haliotrema species (Monogenea: Ancyrocephalidae) from boxfishes (Tetraodontiformes: ostraciidae): relationships within the bodiani group.

The hypothesis that Haliotrema species from boxfishes, which are members of the bodiani group, form a monophyletic lineage was tested. The analysis was conducted for the 19 species of the bodiani group, which includes 8 species from boxfishes, in a matrix of 13 terminal taxa and 14 characters (total of 15 states). A single, most parsimonious cladogram (c.i. = 75%, r.i. = 85%) was generated. The 8 Haliotrema species from boxfishes (H. trochaderoi, H. crymanum, H. lactophrys, H. guadeloupensis, H. glandulosum, H. torridum, H. minutum, and H. kritskyi) were found to form a monophyletic lineage within the bodiani group; 3 of the 14 characters from the analysis were hypothesized to contain homoplastic states.
