dagger-shaped stylet with reinforced walls; coma-shaped
virgula organ; muscular pharynx; short, narrow oesophagus;
three pairs of penetration glands; bean-shaped excretory
bladder and 12 pairs of flame cells. Cercaria sp.
XXVII Malabar n. sp. recovered from Thiara tuberculata
collected from Wayanad district of Kerala has a round to
elongate-oval, spinose body; a highly contractile, spinose
tail; dagger-shaped stylet; muscular pharynx; short
oesophagus; narrow caeca extending up to ventral sucker;

elongate-oval, spinose body; contractile and spinose tail;
dagger-shaped, inwardly curved stylet; virgula organ with
elongated lobes; globular pharynx; three pairs of penetration
glands; bicornuate, transversely elongate excretory
