Thryssatrema hanumantharaoi n. sp., representing a new genus of fellodistomid digenean, is described from a clupeoid
fish, the longjaw thryssa, Thryssa setirostris, collected from the coast of Visakhapatnam, Bay of Bengal. The new genus
is characterized by possessing a combination of the following features: An elongate body; poorly developed suckers; two
oval, symmetrical testes situated in the posterior half of the hindbody; a cirrus sac that extends posterior to the ventral
sucker; a bipartite seminal vesicle; a median genital pore situated immediately anterior to the ventral sucker; a lobed,
pretesticular ovary; uterine coils that fill the entire hindbody; small eggs, elliptical vitelline follicles forming two zones
anterolateral to the ovary; and a V-shaped excretory bladder. The new genus shows affinities to Prudhoeus and Elopsium
but differs from the former in the body shape (elliptical versus oval), and by having poorly developed suckers, more
posteriorly located gonads and elliptical vitelline follicles arranged in two lateral zones in front of ovary. It differs from
Elopsium mainly in the body shape (elliptical versus rounded) and distribution of vitelline follicles and in the V-shaped
excretory bladder.
