The checkerboard worm lizard (Trogonophis wiegmanni) is a species of amphisbaenian in the family Trogonophidae. This is only extant species within the genus Trogonophis, and is endemic to North Africa. Its natural habitats are temperate forests, Mediterranean-type shrubby vegetation, temperate grassland, sandy shores, arable land, and pastureland. It is threatened by habitat loss. They can found in areas with abundant leaf litter, sandy soil and moist soil that is covered with stones and other ground cover. It can also be found near roadsides, in traditionally cultivated areas, in oak forest and oak-juniper forests, in sandy patches with no vegetation and in steppe habitat.
