“…Finally, although most of kudoid species with muscular tropism, including K. thyrsites , develop their plasmodia within the muscle fibers, those of K. kabatai (morphologic myxospore differences already discussed above), K. azoni Aseeva, 2004 , K. crumena Iversen & van Meter, 1967 , K. iwatai Egusa & Shiomitsu, 1983 , K. kenti Burger & Adlard, 2010 and K. yasai Araújo-Neto, da Silva, Hamoy, Matos & Abrunhosa, 2020 have been reported, as K. encrasicoli n. sp. , in interfibrilar location (Burger & Adlard 2010 ; Eiras et al, 2014 ; Cardim et al, 2020 ). The last five species, however, have quadrangular (not stellate) myxospores, SVs with curved edges, and PCs equal or very similar in size.…”

The European anchovy represents the main fisheries for countries in the Mediterranean and Black Sea basins. The skeletal muscle of 13 of 48 (27.1%) Engraulis encrasicolus (L.) specimens from North East Atlantic waters (FAO 27.8.c) was found infected with interfibrillar elongated plasmodia (130-980 µm in length) containing mature myxospores belonging to the genus Kudoa Meglitsch, 1947. No flesh softening was found associated with infection. Fresh myxospores were 10.8 ± 0.7 (9.1-12.3) µm in width 1, 11.3 ± 0.9 (9.5-13.4) µm in width 2, 6.7 ± 0.4 (5.8-7.4) µm in thickness, and 6.9 ± 0.5 (5.8-7.5) µm in length. They were almost stellate in apical view having three pointed-edged shell valves bearing three small polar capsules equal in size 5.0 ± 0.3 (4.4-5.4) μm long and 2.4 ± 0.2 (2.0-3.0) μm wide, and one rounded- to rarely bluntly pointed-edged shell valve bearing a large and particularly wide polar capsule 6.8 ± 0.4 (5.9-7.6) μm long and 4.1 ± 0.2 (3.6-4.4) μm wide. Morphological and morphometrical comparisons between these myxospores and those of Kudoa thyrsites (Gilchrist, 1923) from the clupeid Sardina pilchardus (Walbaum) (North East Atlantic waters, FAO 27.9.a), with which exhibited a similarity of 98.9% and 96.2% using SSU and LSU rDNA sequences, respectively, support the creation of Kudoa encrasicolin. sp. Morphometrical analysis of the polar capsules of flattened myxospores is suggested as a useful approach to differentiate phylogenetically related kudoids with stellate or almost stellate myxospores bearing four polar capsules.
