Results and discussion The community structure of the helminth parasites of the examined hosts is summarized in Table 1.

(1974) (based on the shape and measurements of the hamuli) the Kuwaiti specimens fall within this species. The intestinal stucture shows sometimes the typical arrangement, but the number of the transversal anastomoses may vary from two several ones. The measurements of the hamuli is smaller (1.6-1.8). This species is broadly distributed in the Palearctic realm, in the adjacent countries it was reported from Saudi Arabia (Nasher 1979, Fernando 1989). Sonsinotrema tacapense (Sonsino, 1894) (Figs. 1-3) The genus Sonsinotrema was set up by Balozet Callot (1938) for the species, Distomum tacapense Sonsino, 1894. Among the subsequent authors, Skarbilovich (1948), Dollfus (1951), Khotenovski (1970) have accepted the validity of this genus while others, Dawes (1946), Yamaguti (1971) regarded it to be a synonym of the genus Pleurogenoides Travassos, 1921. Khotenovski (1970) and Yamaguti (1971) applied different characters for the separation of the species-groups (genera) of the subfamily Pleurogeninae Looss, 1899. Yamaguti (1971) combined the oesophageal length with extracaecal ovary and V-shaped excretory vesicle (Pleurogenoides) and short oesophagus combined with intracaecal ovary and Y-shaped excretory vesicle (Pseudosonsinotrema Dollfus, 1951); while Khotenovski (1970) differentiated the genus Sonsinotrema from Pseudosonsinotrema on the basis of the form of excretory vesicle (Ushaped in Pseudosonsinotrema and Y-shaped in Sonsinotrema) and the presence {Pseudosonsinotrema) or absence (Sonsinotrema) of a muscular metraterm.
