sperm storage in blue tounges?

[darwin_freak]

At about Christmas 1985-6, Neil Simpson caught a gravid female T. scincoides at Milperra, NSW (33? 57'S, 150? 58'E). He housed the lizard in the nearby suburb of Bankstown where 23 live young were produced. The adult was retained in a cage by itself and produced a second litter of 12 young the following summer. At no stage did the adult lizard have contact with others of it's own species except for the young produced in 1986 (immediately after birth only). Thus there was no possibility of the female mating with young as in the case documented by Riches (1988). Simpson was unable to recall if unfertilised ova or similar material was passed by the female, although he noted that on both occasions there were no stillborn young (or none observed).
To the best of our knowledge there have been no other evidence for sperm storage documented in T. scincoides. The case documented above may not represent typical behaviour for this species. However assuming this phenomena has gone unreported in this relatively large and common species over the last two hundred odd years, then it may be a similar story for other common Australian reptiles. It is critically important for those who maintain reptiles in captivity to keep accurate contact and reproduction records so that cases of possible sperm storage are more readily diagnosed and hopefully reported

has anyone else heard of this?
