Abstract
Small to medium sized, elongated, flat, delicate distomes with translucent tegument. Suckers weekly developed, and closely proximated. Oesophagus and pharynx present, intestinal caeca simple, may or may not reach posterior extremity. Genital pore median, just anterior to ventral sucker. Seminal vesicle tubular, coiled, cirrus sac absent. Testes usually in posterior body, diagonal or tandem, lobed or branched. Ovary pre-testicular, rarely post-testicular. Vitelline glands follicular, usually in lateral field, generally anterior to level of ovary. Uterus with numerous folds, mainly confined between ovary and genital pore, filled with numerous small and embryonated eggs. Excretory bladder with a long stem and short lateral branches.
