Multiple evolutionary routes of the single polar capsule in Thelohanellus species (Myxozoa; Myxobolidae).

ABSTRACT: Thelohanellus Kudo, 1933 is a species rich genus of Myxosporea, sharing many morphological similarities with species of Myxobolus but the former possesses a single polar capsule, and the latter has two. Based on molecular phylogenetic analyses, this single distinguishing feature is not monophyletic, and members of Thelohanellus are intermixed with Myxobolus species, calling into question the validity of genus Thelohanellus. The occurrence of two polar capsules in a small proportion of Thelohanellus spores as observed in this study suggests that these species have the capacity to express this Myxobolus-like trait, clouding the distinction of these two genera further. Herein, using the most comprehensive data set to date, we explored the phylo
