New record of two genera of Trypanorhynch cestodes infecting Red Sea fishes in Egypt.

Callitetrarhynchus and Floriceps (Lacistorhynchidae: Trypanorhyncha) belong to the less host specific genera with a wide host range. The present study reported plerocerci of Callitetrarhynchus speciosus Linton, 1897 from Conger cinereus, Longfine African Conger (Family: Congridae) and C. gracilis Pintner, 1931 (Family: Lacistorhynchidae) from five new teleost hosts of 2 different families: Lethrinus mehsena, Sky emperor and L.

Ultrastructure of Karyakartia egyptensis Abdou, Dronen and Blend 2006 (Digenea: Lepocreadiidae) from the Red Sea fish, Terapon jarbua.

The tegumental surface of Karyakartia egyptensis Abdou, Dronen and Blend 2006, infecting the Red Sea fish, Terapon jarbua, is described using scanning and transmission electron microscope. Scanning electron microscopy showed that the mouth is surrounded by a single row of 14 digitform tegumental extensions that are seen protruding from the oral sucker. The tegumental surface is covered with posteriorly-directed, multidigitated, scale-like spines that arise from the tegumental enfoldings.

Studies on the juveniles of a species of Anisakis (Nematoda: Anisakidae) from the orangespotted trevally, Carangoides bayad (Carangidae), from the Red Sea, Egypt.

One out of 45 (2.2%) Orange-spotted trevally, Carangoides bayad (Carangidae), collected off the coast of Egypt in the Red Sea was naturally infected with juveniles of a species of Anisakis (Anisakidae). Most of the juveniles were found free in the body cavity and unencapsulated on the surface of the liver.

Karyakartia egyptensis n. sp. (Digenea: Lepocreadiidae: Lepocreadiinae) is described from the intestine of the Jarbua terapon, Terapon jarbua (Forsskål), collected from the Red Sea off the coast of Hurghada, Egypt.
