Trematodes of Fishes from the Red Sea. Part 4: On Some New and Known Forms with a Single Testis

Abstract

The material upon which this description is based consists of 58 specimens obtained from Anampses sp. locally called Malas. This trematode is small and lanceolate in shape and its size is fairly constant. It measures 0.86 to 1.135 mm in length, and 0.383 to 0.449 mm in maximum breadth about the middle of the body. The cuticle is provided with comparatively thin and long spines. The ventral sucker is slightly smaller than the oral, measuring 0.117 to 0.135 mm in diameter, and is situated slightly anterior to the middle of the body.
