Callorhynchocotyle Suriano & Incorvaia, 1982 View in CoL

Amended diagnosis. Body elongate, robust with smooth tegument. Haptor asymmetrical containing 3 suckersclerite complex pairs (sensu Boeger & Kritsky 1989). Complex 1 sucker sclerites smaller than or similar to those of complex 2 and 3. Haptoral longitudinal axis at an angle to that of body proper. Oral and haptoral suckers papillate or non-papillate. Pair of hamuli present between pair of terminal suckers of the dorsal appendix. Hamulus root base angle obtuse. Branched intestinal caeca unite posterior to testes; extends into haptor. Testes numerous, irregular in shape. Vas deferens dorsal to uterus, sinuous, glandular for the majority of its length. Single loop of vas deferens proximal to base of cirrus complex, present or absent. Unarmed cirrus muscular with or without bulbous distal region, without prostatic region. Genital pore at level of or immediately posterior to initial intestinal bifurcation. Ovary anteriorly lobate or branched, situated sinistral or dextral to body proper midpoint. Descending ovarian branch coiled or sinuous, narrowing proximally to form oviduct. Oviduct branches to form reduced sac-like seminal receptacle before receiving thin descending branch of vitelline duct, thereafter expands to form smooth ootype. Uterus dorsal to ovary, initially narrow, widening anteriorly. Ovate eggs connected by elongate tendril forming at each end. Vaginal pores muscular, opening ventrally, lateral to cirrus. Parallel vaginal ducts with glandulo-muscular distal region, narrowing thin-walled proximal region running with intestinal caeca but often obscured by vitellarium. Follicular vitellarium extending from region immediately level with or posterior to vaginal pores, forming bi-lateral bands up to but not including the haptor. Excretory pores anterior to vaginal pores, opening laterally at margin of body proper. Parasites of members of the subclass Holocephali including the Callorhynchidae and Chimaeridae .
