Summary
A new species of trypanorhynch is described from blastocysts found within the gill arches of Scomberomorus commersoni caught off eastern Australia. It differs from other members of the genus in having 9 to 10 hooks per principle row, scattered intercalary hooks that merge with the band of small hooks, and a well-developed basal armature. Developing stages were found both within and outside branchial blood vessels. Thousands of fully developed blastocysts were within the gill arches. Around and between them was fibrous tissue, haemorrhage, and evidence of chronic inflammation. ac]19810210
