The reproductive cycle of the Namaqua sand lizard, Pedioplanis namaquensis, from southern Africa is described from histological examination of gonadal material from museum specimens. Males followed a seasonal testicular cycle in which sperm was produced in January–March and September–December. Testes in regression were present in March and May. Females with enlarged ovarian follicles (>4 mm length) or oviductal eggs were collected between November and February. Clutch size for 14 females was 3.8 ± 0.97 S.D. eggs, range 3–5. Histological evidence is presented that two clutches may be produced in the same reproductive season.
