D63787F6FFCAFFF1FCB91C0F0C4BFB27.taxon	description	Description of the spores: The spores of Kudoa viseuensis n. sp. were 7.2 ± 0.2 μm in length and 5.2 ± 0.2 μm in width (Figure 3). In the apical view, the polar capsules were 1.8 ± 0.2 μm in length and 1.3 ± 0.1 μm in width. When observed laterally, the mean length was 2.7 ± 0.2 μm and the width was 1.3 ± 0.1 μm (Table 1). Table 1 compares the dimensions of the spores and polar capsules (and the shape of the spores) of other Kudoa species with Kudoa viseuensis n. sp. (Cnidaria: Myxozoa: Myxosporea: Multivalvulida: Kudoidae). Kudoa viseuensis n. sp. was restricted to the skeletal musculature of the host, and was not found in any other organ of the host fish. The morphological comparisons indicated that Kudoa viseuensis n. sp. is most similar to K. orbicularis (Azevedo et al. 2016) in terms of the width of the spore and the polar capsule, although other dimensions are clearly distinct from those of this species, and other Kudos species, studies previously. These findings, to- gether with the molecular data (see below) lend support to the present description of the new species.	en	Monteiro, Elideth Pacheco, Da Silva, Diehgo Tuloza, Sanches, Osimar, Hamoy, Igor, Matos, Edilson Rodrigues (2019): Morphological and Molecular Characteristics of Kudoa viseuensis n. sp.

D63787F6FFCAFFF1FCB91C0F0C4BFB27.taxon	discussion	Phylogenetic analyses A partial sequence of 1400 base pairs (bps) of the SSU rDNA gene was obtained from the spores of Kudoa viseuensis n. sp., found in the musculature of B. surinamensis. This sequence was deposited in GenBank under accession number MK 256272. The phylogenetic tree generated by Bayesian Inference defined a major clade, denominated clade A, composed of species of the genus Kudoa (Figure 4), which is subdivided into two clades, denominated A 1 and A 2, with high support (posterior probabilities). Each of these clades was influenced strongly by the tissue tropism of the parasites, with Kudoa viseuensis n. sp. being included in subclade A 2. Subclade A 1 is composed of Kudoa species that parasitise the musculature, brain, and intestine of fish- es. Kudoa viseuensis n. sp. is included in subclade A 2, which is basal to A 1. Kudoa viseuensis n. sp. parasitizes the musculature of the marine fish B. surinamensis, and clusters with Kudoa orbicularis (Azevedo et al. 2016), a parasite of the musculature of the freshwater fish, Chaetobranchopsis orbicularis. In this arrangement, K. orbicularis is the sister species of Kudoa viseuensis n. sp., and the two species not only share the infection site, but are also found in the same geographic region. The outgroup is composed of species of the genus Unicapsula Davis, 1924, a member of the order Multivalvulida Schulman, 1959, which infects the musculature of its hosts. A new alignment was run for the pairwise comparison of key Kudoa species with Kudoa viseuensis n. sp. (Table 2). The smallest pairwise genetic distance (p) found in this analysis between Kudoa viseuensis n. sp. and the other Kudoa species was 3.9 % in the case of K. orbicularis (KM 192365), while the greatest distance was 4.9 % for K. rosenbuschi (AY 623795).	en	Monteiro, Elideth Pacheco, Da Silva, Diehgo Tuloza, Sanches, Osimar, Hamoy, Igor, Matos, Edilson Rodrigues (2019): Morphological and Molecular Characteristics of Kudoa viseuensis n. sp.
