Ligophorus hamulosus Pan & Zhang,sp.nov. (Figs. 1-4) Type specimens No.:HHK9605-15.Host: Liza macrolepis .Location:Gills.Localit y:Haikou (20 06°N ,110 38°E ) ,Hainan Island.Date:Nov.5,1996. Body of medium size,0 560-0 702×0 127-0 146?mm.Pharynx 0 015-0 018×0 015-0 020?mm.Opisthohaptor 0 075-0 118×0 068-0 070?mm in size.Marginal h ooklets 0 012-0 015?mm in length.Ventral central large anchors 0 027-0 029 ?mm in total length,basal portion 0 020-0 023?mm,point about 0 003?mm,i nner root 0 009-0 013?mm,outer root 0 004-0 050?mm.Ventral connective pla t e 0 007-0 009×0 033-0 038?mm.Dorsal central large anchors 0 020-0 023?m m in total length,basal portion 0 015-0 018?mm,point about 0 003?mm,inne r root 0 009-0 013?mm,outer root 0 004-0 005?mm Dorsal connective plate 0 004-0 005×0 038-0 040?mm in size. Copulatory organ 0 025-0 043?mm in total length.Copulatory tube thin,C shap ed curved,0 055-0 063?mm in length according to its curvature,diameter of m iddle part about 0 002?mm.Supporting apparatus 0 020-0 030?mm in length.Vag ina being funnel like and thin,0 020-0 023?mm in length.Eggs 0 065-0 098× 0 050-0 078?mm in size. Description is based on 10 specimens. This worm is similar to Ligophorus imitans Euzet & Suriano,1977,b ut differs from the latter by ①the shape and the structure of the central ancho rs,②the different size and the chitinous measurement between the ventral and t he dorsal central large anchors and ③the structure of the copulatory apparatus.
