|Distribution||Australia (New South Wales, South Australia, Tasmania, Victoria)|
Type locality: Van Diemen's Land (= Tasmania); original description cites Kangaroo Is., S. A.
|Reproduction||oviparous. Bassiana duperreyi has been studied because of its extraembryonic membrane development which seems to be significant for the evolution of placentation. There seems to be both temperature-dependent (TSD) and genetic sex determination (GSD) in this species (SHINE et al. 2002). Radder et al. (2009) show that sex in this species also depends on egg size. In fact, if (and only if) eggs are incubated at low temperatures, removing yolk from a newly laid egg turns the offspring into a male. Adding yolk from a larger (but not smaller) egg turns the recipient egg's offspring into a female. Remarkably, then, offspring sex in this species is the end result of an interaction between three mechanisms: sex chromosomes, nest temperatures, and yolk allocation. Dissanayake et al. (2021) show that nests have become deeper over 20 years, possibly in relation to climate change. Increasing elevation and decreasing nest temperature increases sex reversal in genotypical XX females to males.|
|Types||Lectotype: MNHN-RA 7102 (total length 131.5 mm), from Tasmania designated by Rawlinson (cited as “in prep.” by COGGER 1983).|
|Comment||Nomenclature of this species need revision.|
Synonymy: partly after SHEA & SADLIER 1999.
Type species: Tiliqua duperreyi is also the type species of the genus Bassiana HUTCHINSON et al. 1990. Probably listed in error by FRANK & RAMUS 1995.
|Etymology||Named after Captain Louis-Isadore Duperrey (1786-1865), a French naval officer.|
