Redescriptions of dichelyne (dichelyne) rasheedae Petter, 1974 and Spirocamallanus olseni Campana-Rouget & Razarihelissoa, 1965, recorded for the first time from fish in Lake St. Lucia, South Africa.

During a survey of parasites of fish in Lake St. Lucia, KwaZulu-Natal, South Africa, Dichelyne (Dichelyne) rasheedae was recovered from the intestines of Pomadasys comersonnii and Rhabdosargus sarba, and Spirocamallanus olseni from Rhabdosargus sarba. These are new host and geographical records. Both species of nematodes are redescribed and figured by use of light and scanning-electron-microscopical techniques, and additional morphological data are provided.
