Amended diagnosis
A small trig (body length 4 to 5 mm), with black body and yellow legs, very similar to Trigonidium (Trigonidium) maoricum in every aspect. Slightly smaller than the latter, it has a shorter stridulatory file with less than 20 teeth. Adult insects come in a wingless morph without hindwings or auditory tympana, and in a winged morph with hindwings and with auditory tympana. The winged morph was previously mistaken to be a different species, Trigonidomorpha sjostedti.
Etymology
The Latin adjective australianum refers to the country the insect is found in.
