ward, 1996). Vincent's sillago, Sillago vincenti McKay, 1980: Kavanad, Kerala, India (Hayward, 1996). SPECIMENS STUDIED: 14 voucher specimens, USNPC 89007, 89008, HWML 15022. REMARKS: Diplectanum sillagonum was described by Tripathi (1957) from the gills of S. sihama from western coastal localities on the Bay of Bengal, India. His description of this species is of marginal value for species determination. Nonetheless, the original drawings of the copulatory complex, anchors, bars, and whole mount, while diagrammatic, strongly suggest conspecificity with our collection from the Persian Gulf. Persian Gulf specimens were obtained from the same host species as that of the type series, and respective measurements of specimens from the Persian Gulf and India are comparable. However, the types of D. sillagonum were not available for confirmation. General morphology of the sclerotized haptoral structures and copulatory complex generally corresponds to figures of this species offered by Hayward (1996). However, Hay ward (1996) did not mention the presence of the midventral pouch located anterior to the pharynx in his redescription of the species. Lepidotrema kuwaitensis sp. n. (Figs. 16-23) DESCRIPTION: Diplectaninae. Body 504 (452—603; n — 8) long, fusiform; greatest width 105 (90-121; n = 9) near body midlength. Tegument smooth. Cephalic margin tapered; 2 terminal, 2 bilateral cephalic lobes poorly developed; 3 bilateral pairs of head organs with anterior, posterior pairs associated with respective cephalic lobes; cephalic glands not observed. Eyes 4, equidistant; members of posterior pair larger than anterior members; anterior eyes frequently absent, 1 or both posterior eyes occasionally dissociated; granules small, ovate, numerous accessory granules at eye level. Mouth subterminal, ventral to pharynx; pharynx 23 (19-26; n = 9) wide, ovate to subspherical; esophagus short to absent; intestinal ceca blind. Peduncle short to elongate. Haptor 83 (65-100; n = 9) long, 139 (124-151; n = 9) wide, bilaterally lobed. Squamodiscs similar, each 37 (26- 43; n = 4) long, 40 (27-48; n = 6) wide, subcircular, with 8-10 concentric rows of dumbbellshaped rodlets becoming progressively more KRITSKY ET AL.—DIPLECTANIDS FROM KUWAIT 151 delicate in posterior rows; 2-4 rows (layers) of elongate delicate spinelets wrap around posterior margin of both squamodiscs, spinelets frequently absent. Ventral anchor 42 (39-45; n = 25) long, with elongate roots (deep root longest), evenly curved shaft with terminal indentation at articulation with recurved point; point extending slightly past level of tip of superficial anchor root; anchor base 9 (7-11; n = 13) wide. Dorsal anchor 37 (32-40; n = 23) long, with narrow base, long deep root, curved shaft, point extending past level of tip of superficial root of anchor base; anchor base 7 (6-9; n = 11) wide. Ventral bar 59 (52-66; n = 21) long, with tapered ends, ventral groove; paired dorsal bar 55 (47—60; n = 23) long, spatulate, with posteromedial spine. Hook 10 (9-12; n = 37) long, with protruding thumb with slightly depressed end, delicate point, shank dilated slightly in some specimens. Hook pair 1 lying medial to haptoral lobes, posterior to bars; pairs 2-4, 7 in lateral haptoral lobes; pair 5 associated with shaft of ventral anchor; pair 6 at level of or just anterior to dorsal bar. FH loop shank length. Male copulatory organ 68 (60-74; n =11) long, a sigmoid tube with wall of varying thickness along length, acute tip. Accessory piece absent. Testis subspherical, 54 (42-65; n = 9) in diameter; course of vas deferens not observed; seminal vesicle a simple dilation of vas deferens, lying along body midline dorsal to ootype; prostatic reservoirs 3, saccate; anterior prostatic vesicles bilateral to male copulatory organ, with prostatic ducts fused prior to entering base of male copulatory organ via common duct; posterior reservoir caudal to male copulatory organ, apparently emptying independently into base of male copulatory organ. Ovary 23 (19—25; n = 3) wide, pyriform, anterodorsal to testis, looping right intestinal cecum; oviduct elongate; ootype ventral, a small dilated portion of female duct; uterus delicate, extending anteriorly to left of prostatic reservoirs; seminal receptacle not observed; vaginal aperture sinistroventral, with circular muscular rim; vagina funnel-shaped, narrowing to short tube; vagina with proximally thickened walls; vitellaria throughout trunk, except absent in regions of major reproductive organs. Egg 83-84 (n = 1) long, 56-57 (n = 1) wide, ovate, with short proximal filament. TYPE HOST: Small-scaled terapon, Terapon puta (Cuvier, 1829) (Terapontidae).
