A table of developmental stages of the target species is useful for studying the development of any animal. Although tables of developmental stages have been established for several squamates, none has been published for gekkonid lizards. We have established a table of developmental stages for the Madagascar ground gecko Paroedura pictus. The table includes 27 embryonic stages from oviposition to hatching based on chronology and external morphology. The interval from oviposition to hatching is 60 days. Eleven to sixteen somites were observed at oviposition, and 5 to 6 somites were formed each day. Limb bud swellings were recognized by the third day after oviposition. After 2 weeks of incubation, the presumptive autopod was detected by carpal/tarsal cartilage formation. Cartilages in all digits were seen by 3 weeks after oviposition. Skin pigment was visible after 4 weeks incubation, and the skin color pattern was apparent 40 days after oviposition.
目标物种的发育阶段表对于研究任何动物的发育都很有用。尽管已经为几种有鳞目动物建立了发育阶段表，但还没有关于睑虎科蜥蜴的发育阶段表发表。我们已经建立了马达加斯加地虎蜥（Paroedura pictus）的发育阶段表。该表包括从产卵到孵化的27个胚胎阶段，这些阶段是根据时间顺序和外部形态确定的。从产卵到孵化的间隔为60天。产卵时观察到11至16个体节，每天形成5至6个体节。产卵后第三天可识别出肢体芽肿胀。孵化2周后，通过腕骨/跗骨软骨形成检测到假定的手足。产卵3周后可见所有指骨的软骨。孵化4周后可见皮肤色素，产卵40天后皮肤颜色模式明显。
