Abstract	During studies of amphibian sperm cryopreservation, a new species of myxosporidean parasite (Myxozoa, Myxosporae) was observed in the testes of the Australian dwarf green tree frog Litoria fallax (Peters). Myxosporidiasis was found to have no affect on L. fallax body condition or sperm numbers. Myxobolus spores from L. fallax are morphologically distinct from Myxobolus hylae spores (infecting the sympatric Litoria aurea Lesson) and the three previously named (exotic to Australia) Myxobolus species found in anurans. Myxobolus fallax n. sp. is characterised by: pseudocyst white, spherical to ovoid, 141 ×74 to 438 ×337 μm in diameter (mature); plasmodium with spores loosely arranged within interior. Spores ovoid 13.4 ± 0.5 (12.6–14.6) μm length, 9.5 ± 0.4 (8.3–10.6) μm width, 6.8 ± 0.4 (6.5–7.6) μm depth, 1.4 ± 0.1 (1.3–1.6) length/width; polar capsules broadly pyriform and equal in size 4.2 ± 0.3 (3.3–4.7) μm length, 2.4 ± 0.2 (2.1–2.8) μm width; filament coils 7–8, wound tightly and perpendicular to the longitudinal axis of the capsule; polar filament 34 ± 7.0 (18–50) μm length; intercapsular appendix and sutural ridge folds absent; and iodinophilous vacuole and mucous envelope lacking. In addition to this new species, data from archival samples of M. hylae are provided which show two morphologically distinct spore types. Both appeared rarely in the same pseudocysts and we cautiously retain the single species.
