|Comment||Nomenclature of this species need revision.|
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.
Type species: Tiliqua duperreyi is also the type species of the genus Eulepis. Probably listed in error by FRANK & RAMUS 1995.
