Morphological measurements and meristic character counts for four genetic lineages identified in species tree analyses (Fig. 3).

T. tetraporophora sensu stricto; Roma-area; Darling Downs; and Normanton-area. All measurements are in mm and mean (± SE) are provided. Abbreviations are: snout-vent length (SVL), head length (HL), head width (HW), head depth (HD), axilla – groin length (AG), hind limb length (LL), number of inter-nasals (IN), number of infralabials (IL), number of supralabials (SL), number of scales between nasal and supralabial (NS), number of sub-digital lamellae on longest toe (SLAM), number femoral pores (FP); number of pre-anal pores (PP), tail length (TailL), and number of sub-ocular scales (SO).
