Extract

1. The anatomy of Apharyngostrigea (Apharyngostrigea) simplex (Johnston, 1904) new comb, from young cattle egrets is described in detail, involving the reconstruction of its internal organisation from serial sections.

2. The relationships of the species within the genus Apharyngostrigea Ciurea, 1927 is discussed using the method of Numerical Taxonomy by Sneath and Sokal (1902). It is found that the original genus can be split into two genera. The genus Apharyngostrigea comprises two subgenera; Apharyngostrigea (Apharyngostrigea) n. subgen. and A. (Brasiliana) n. subgen. made up of seven species groups. The generic diagnosis of Apharyngostrigea Ciurea, 1927 and Chaseostrigea n. gen. are given as well as a key for separating the species of the genus Apharyngostrigea.
