Host: Lagocephalus lunaris (Tetraodontidae) Site: intestine Distribution: Kuwait Bay (near Towers) Prevalence: 89.5% Mean intensity: 7.5 Abundance: 8.5 This description was based upon the examination of 36 gravid whole-mounted worms and specimens examined under scanning electron microscope (Fig. 1). Description: Body elongate and uniform, rounded at both ends. Body 650-1,025 in length, 300-380 in width, widest just beyond the ventral sucker. Along the lateral sides of body longitudinal folds present, bending ventrally and ending at posterior extremity (Fig. L). Tegumental spines minute, seen on ventral side of body anterior to ventral sucker. Numerous parenchymal gland cells found in anterior part of body, extending to ventral sucker. Oral sucker subterminal 70-104 by 65-113. Pharynx 65-95 by 65-78, prepharynx and oesophagus very short, often unrecognizable. Caeca bifurcate in front of ventral sucker. Intestine thick, opening outside through separate ani one on each side of excretory pore (Fig. 1). Ventral sucker smaller than the oral one, measuring 67-90 by 65-90. Testes almost entire, tandem, in posterior half of body; anterior one 85-104 by 88-130; posterior one 104-130 by 85-130. Cirrus pouch club-shaped, 120-128 by 40-50, cirrus thick, protrusible; internal seminal vesicle ellipsoidal, pars prostatica claviform; external seminal vesile curved, lying free in parenchyma. Genital atrium small; genital opening sinistral at level of bifurcation. Ovary deeply lobed, median, pre-testicular, composed of 7 to 10 lobuli; measuring 80-100 by 45-60. Metraterm simple, along left side of cirrus pouch, opening separately in genital atrium. Vitellaria strongly developed, vitelline follicles big filling all available place in hindbody extending to anterior part of ventral sucker, some follicles confluent medially. Uterus arranged in a few intercaecal coils. Eggs few, thin shelled, operculated and not embryonated; measuring 59-65 by 34-36. DISCUSSION Bianium arabicum sp. n. belongs to the species group the members of which are allocated to the subfamily Diploproctodaeinae Park, 1939. This subfamily comprises the following 11 genera: Diploproctodaeum La Rue, 1926; Bianium Stunkard, 1930; Diploporus Ozaki, 1928; Diplocreadium Park, 1939; Amarocotyle Travassos, Freitas et Bührnheim, 1965; Cotylocreadium Madhavi, 1972; Diploproctodaeoides Reimer, 1981;
