ABSTRACT
Callitetrarhynchus and Floriceps [Lacistorhynchidae Trypanorhyncha] belong to the less host specific genera with a wide host range. The present study reported plerocerci of Callitetrarhynchus speciosus Linton, 1897 from Conger cinereus, Longfine African Conger [Family Congridae] and C. gracilis Pintner, 1931 [Family Lacistorhynchidae] from five new teleost hosts of 2 different families Lethrinus mehsena, Sky emperor and L. variegatus, Variegated Emperor [Lethrinidae]; Cephalopholis miniata, Coral grouper, Epinephe-us polyphekadion, Small toothed grouper or camouflage grouper and Epinephelus summana, Summana grouper [Serranidae]. C. gracilis is characterized by an elongated scolex, 2 bothria, lacking a pars post bulbosa, elongated bulbs, a poeciloacanthous atypical metabasal armature with 7 principal hooks, and a chainette. Tegumental surface is covered with polymorphic microtriches palmate [tetra, penta, hexadigitate], tricuspidate, bifurcate and filiform. For the first time, tufts of filamentous microtriches surrounding a cilium are recorded from C. gracilis proximal bothrial surface obtained from L. variegatus. Seven new host are recorded for the related lacistorhynchid Floriceps minacanthus, Lethrinus nebulosus Spangled Emperor, Lutjanus bohar 2 red spots Snapper, Lutjanus fulviflamma Dory snapper, Epinephelus polyphekadion Small toothed grouper, E. summana Summana grouper, Variola louti Lunartail grouper, and Spharaena qenie Blackfine Barracuda
