| Distribution | Australia (Western Australia) Type locality: W. A. |
| Reproduction | ovovivparous. |
| Types | Holotype: BMNH 1946.1.21.73 |
| Diagnosis | Diagnosis: A medium-sized, moderately slender species of Suta (total length to 523 mm* this study, males mean 331 mm, females 297 mm) with: 15 midbody scale rows; 136‒174 ventrals; 22‒41 subcaudals; 136‒178 vertebrals; typically undivided fourth infralabials; variable body colouration of reddish brown, pale orange to bright red or beige, occasionally with a dark vertebral stripe or zone along the body; body scales often with dark pigment of black base or blotch extending back as fine to thick edge on the anterior facets, posterior facets without dark edge; typically near-complete black hood on the head extending back on to first 3‒8, mostly 5 vertebrals on the nape; variably sized pale markings in front of the eyes, occasionally across the snout; typically with minimal pale indents behind the eyes, rarely extending above the upper primary temporals. *B. Maryan has observed a total length of 560 mm in S. gouldii (Maryan et al. 2020: 8). Additional details (4230 characters) are available for collaborators and contributors.

| Comment | Venomous! Type species: Elaps gouldii GRAY 1841: 91 is the type species of the genus Parasuta WORRELL 1961. Synonymy: Maryan et al. 2020 synonymized Parasuta spectabilis bushi (STORR 1988) and Parasuta spectabilis nullarbor (STORR 1981) with Suta gouldii (and removed the two subspecies from Parasuta spectabilis (KREFFT 1869). Distribution: see map in Maryan et al. 2020: 14 (Fig. 5). Records from NSW have been referred to S. dwyeri and S. nigriceps. Habitat. Suta gouldii occupies a variety of temperate to semiarid vegetation associations growing on light to heavy soils, including near-coastal sand dunes, dry sclerophyll forest of mallee and/or other Eucalyptus L`Hëritier, woodlands, heathlands, shrublands including chenopod, and rock outcrops (Wilson & Knowles 1988; Ehmann 1992; Bush et al. 2007; Cogger 2014; Wilson & Swan 2017). The habitat near Bungalbin Hill where S. gouldii is known from consists of a yellow sandplain with Banksia elderiana Mueller & Tate shrubland over Triodia scariosa Burbidge (Newbey & Hnatiuk 1985; B. Maryan, pers. obs.). In these vegetation associations, specimens of S. gouldii particularly during cooler weather can be raked from deep leaf litter, spoil-heaps, piles of dead vegetation and abandoned stick-ant Iridomyrmex conifer Forel nests, found in dead grass trees Xanthorrhoea Smith and decaying logs and under logs, mallee roots, ground-strewn bark, rocks and rubbish, especially pieces of old iron in disturbed agricultural areas adjacent to uncleared vegetation. Additionally, when seasonal activity is optimum, S. gouldii can be funnel or pit-trapped in buckets and nocturnally observed while driving or head-torching on roads, tracks and open ground. Bush et al. (2010: 152) mention activity on roads in the Darling Range during winter, suggesting S, gouldii is very cold tolerant. Some degree of habitat partitioning occurs in the Kambalda region, where S. gouldii generally prefers the woodlands on light soils and S. monachus the shrublands on heavy, often stony soils (P. Orange, pers. obs.). (Maryan et al. 2020: 13). |
