We present a photometric study of the newly discovered eclipsing intermediate polar J183221.56-162724.25 (in short J1832) with an orbital period 8.87 h. The system features box-like deep eclipse full width at 50% depth 1970 ± 2 s and large-amplitude coherent pulsation Pobs = 65.18 min, which represents either synodic (beat) or spin white dwarf (WD). ratio is Pspin/Porb 0.1091 0.1225, respective...

Two new species of Henneguya (Myxozoa) were described from specimens collected on the gills of Hoplosternum littorale (Hancock, 1828) (Callichthyidae) and Cyphocharax gilbert (Quoy and Gaimard, 1824) (Curimatidae), from Guandu River, State of Rio de Janeiro, Brazil. The species described were compared with the related species of the genus. The new species of Henneguya parasitic on H. littorale ...
