ABSTRACT
Redescription of Myxobolus magellanicus Szidat, 1953 from gills of
Galaxias maculatus
is done to complete Szidat's description. Fixed spores are subspherical,
biconvex in sutural view with straight sutural line, are 11.9 ± 0.6 µm
long and 12.9 ± 0.5 mm wide. Infection is
seasonal and has a negative correlation with water
temperature. Prevalence is independent of host's sex and decreases with
host's length. Prevalence in 17 Patagonian Andean lakes
(from 40°10' to 41°30'S) was ranging between 3.2 and 35%.
