Summary
A new genus, Amirthalingamia, is erected for Paradilepis macracantha, which is redescribed, as a larval form from Tilapia nilotica, and as an adult from Phalacrocorax carbo, from the Green Belt, Sudan. It differs from other Dilepididae in having large rostellar hooks of three sizes, in two rows, arranged in a bilaterally symmetrical pattern. Two other dilepidid larvae, believed to belong to Parvitaenia and Paradilepis were also found in T. nilotica.
