|Distribution||desert regions of E Western Australia, N South Australia, Northern Territory to W Queensland and New South Wales|
Type locality: Misisonsstation Hermannsburg, oberer Finke-Fluss, Nord-Territorium.
|Types||Lectotype: SMF 10349, from Hermannsburg Mission, upper Finke River, N. T., designated by MERTENS 1967|
|Diagnosis||Diagnosis. A species of Tympanocryptis with rostral scale separated from the canthus rostralis, nasal scale extending dorsally across the canthus and bordered below by enlarged scales, no lateral neck fold, dorsal head scales keeled, enlarged dorsal spinous scales roughly aligned longitudinally, ventral and throat scales keeled, colour pattern geographically variable, from strongly five-lined and weakly dimorphic in the south to more weakly patterned and with stronger sexual dimorphism in the north, ventral surface white with weak throat speckling [Melville et al. 2019: 27].|
Comparison with other species. No other Tympanocryptis species co-occur with T. centralis. Distinguished from its close relative Species E, which occurs further north, by strongly patterned males and usual presence of keels on the throat scales. The species that abuts the range of T. centralis most closely is T. tetraporophora, which can be superficially similar in having well-patterned males and often almost patternless females. Tympanocryptis centralis is distinguished by lacking a pair of femoral pores, by a pale transverse supra- orbital bar (usually discernible) and by the dorsal tubercles tending to be arranged in longitudinal series [Melville et al. 2019: 27].
|Comment||Habitat. Occurs on arid stone deserts, stony slopes skirting rocky hills or loams with scattered stones and spinifex grass (Triodia spp.) associated with desert ranges (Melville et al. 2019: 28).|
