These specimens are deposited in Marine Biology Laboratory,Science Center, Shantou University. All measurements are in millimetres,unless otherwise noted. 1 Stephanostomum carangi sp. nov (Fig. 1) Host: Caranx ( Caranx ) ignobilis ;Locality:Intestine;Location:Dongshan Island,Fujian Province;Date:Dec. 25,1996;Infection:2 specimens from 1 host. Description:Body 2 08～3 04 long,0 47～0 56 wide in acetabular region. Cuticle spinoes to the level of testicular region,body spines up to 24～40μm. Oral sucker approximately funnel shaped,(0 144～0 169)×(0 204～0 232). Circumoral spines 36 in number,in two alternating,uninterrupted rows. Ventral median aboral spine 28μm×6μm;ventral median oral spine (46～50)μm×8μm;dorsal median aboral spine 84μm×11μm;dorsal oral spine 84μm×11μm. Acetabulum (0 144～0 204)×(0 168～0 188),sucker length ratio 1∶1 00～1 275. Prepharynx 0 336～0 624 long. Pharynx barrel shaped,(0 196～0 216)×(0 096～0 124). Esophagus 0 056～0 080 long. Ceca opening into excretory vesicle near posterior end of body. Testes nearly elliptical,contiguous,diagonal. Anterior testis 0 296×0 244,and posterior one 0 416×0 224. Posttesticular space 0 208mm long. Cirrus pouch (0 504～0 640)×0 112. Seminal vesicle (0 176～0 224)×(0 048～0 096). Ejaculatory duct 0 28～0 384 long,with fine spines. Genital pore immediately preacetabular. Ovary (0 144～0 208)×(0 184～0 196),immediately pretesticular or slightly overlapping anterior testis. Vitellaria commencing 0 16～0 20 postacetabular,extending along ceca and conflent in posttesticular area. Egg (65～70)μm×(40～46)μm in life. This species resembles with S. ghanensis Fishthal et Thomas, 1968 in the arrangement of organs,but differs from S ghanensis in the size of body,circumoral spines,eggs,sucker length ratio and the posttesticular
