Abstract

The final instar larvae of the two species of the southern African gomphid genus Ceratogomphus, the South African endemic C. triceraticus and the more widespread C. pictus, are compared based on exuviae. Main differences are the shapes of the prementum and of the last abdominal segments, giving C. pictus a more slender and pointed appearance. Ceratogomphus triceraticus is slightly larger and on average significantly so. The habitats of both species are described based on own observations in South Africa.
