Sorry in advance, but my advice won't be worth much. I did some checking on a breeding database and found only two records of captive breeding of this species. One was Philly Zoo, and all 8 hatchlings died. The other breeding was two successful hatches from a single clutch, private individual - no status available. Also, among zoos that report to the International Species Information System , there is no indication that the very small handful of zoos with Zonosaurus spp. have had any success with breeding. You're pretty much on your own with the species. What little I know indicates they are difficult to breed and there is little if any difference between the sexes. I would suggest that maybe Gerrhosaurus incubating techiniques might be worth a try. Ingo Kober, who's been known to post here on occasion as had some success with at least one species of Gerrhosaurus. He indicated in an email communication to me that they needed very high ambient humidity early on in the incubation, tapering off to very little humidity during the last part of the incubation. Good luck. If you do have success eventually, don't hestitate to share any information on this forum.
