DiagnosisDiagnosis. Distinguished from other Tympanocryptis by the following combination of character states: presence of two pre-cloacal pores, lack of longitudinal stripes on the dorsum, presence of enlarged scales with raised spines arranged in transverse rows of 2–5 scales on dorsum, snout straight or convex, scales on snout smooth with low keels, rostral width ~2–3 times height, keels on scales of upper arm aligned, well-defined row of enlarged scales at anterior and dorsal edge of thigh forming conspicuous ridge, scales on dorsal surface of thigh usually aligned, ventrals with low keels, and light reddish-brown coloration, often with blackish sides.

Comparison with other species. Tympanocryptis fortescuensis sp. nov. is mostly likely to be confused with T. cephalus and T. diabolicus sp. nov. It is distinguished from T. cephalus by possessing enlarged dorsal scales in short transverse rows in rows of 2–5 scales (versus 5–7), enlarged row of scales at front of thigh forming a conspicuous ridge (versus weakly-defined row), scales on upper thigh usually aligned, and uniform light reddish- brown dorsum with at most only subtly discernible blotches along midline (versus brown with dark blotches).
Tympanocryptis fortescuensis sp. nov. is distinguished from T. diabolicus sp. nov. by having scales on snout with low keels (versus rugose with feeble keels) and light brown coloration rarely possessing dorsal blotches (versus rich reddish-brown occasionally with blotches). 
EtymologyThe specific name is in reference to the Fortescue basin or marsh, formed by the Fortescue River, where this species occurs.
