Testudinidae The genus Kinixys includes eight species and one subspecies of tortoise found throughout sub-Saharan Africa and Madagascar. Although Kinixys tortoises are listed as CITES Appendix II, they are in decline in many areas for a variety of reasons including, but not limited to, habitat loss and collection for the pet trade. Experience with Kinixys tortoises in captivity is somewhat limited, specifically conditions required for successful captive breeding. The purpose of this study was to identify indoor conditions required for captive propagation of Kinixys spekii (K. s.) and Kinixys belliana nogueyi (K.b.n.). We maintained 2.2 K.s. and 2.5 K.b.n. indoors in naturalistic enclosures with manipulation of climate and light cycle to simulate the environment in their home ranges. Both K.s. and K.b.n. successfully reproduced over several seasons under similar captive conditions. Initial incubation regimens for K.s. did not result in egg development until a diapause was employed. Incubation period ranged from 210–270 days. Kinixys belliana nogueyi eggs developed without diapause with the incubation period ranging from 180–220 days. While not imminently endangered, pressures do exist which are impacting Kinixys tortoises across their home ranges. While experience is somewhat limited regarding captive care of Kinixys tortoises, captive maintenance can be successful and utilized to help ensure their future survival. Collaboration with those maintaining reproductive groups of K.s. and K.b.n., both within zoos and private collections, will be important to this end going forward.
