Gotocotyla travassosi sp. n., gastrocotilideo de brânquias de enchova (Polistomata)

Abstract

<abstract language="eng">In this paper a new species of the genus Gotocotyla Ishii, 1936, is described. It differs from the known ones by the form of the ovary

Revision of the monogenean family Gotocotylidae (Polyopisthocotylea)

“…However, this upper limit of copulatory organ length is undoubtedly a typographical error, as two paratype specimens collected by Kohn et al (and examined in this paper) had copulatory organs 180 and 140 long; furthermore, the scale bars in all three of their illustrations of the male copulatory organ indicate that the true size was less than 200. Kohn et al (1971) also recorded copulatory spines 3036 long; but again, their illustrations and our measurements indicate that the length of the spines fall within the range noted in the present study, 1022. Kohn and Cohen (1998) recently considered S. travassosi to be a synonym of G. acanthophallus, but did not formally synonymise the two names.…”

“…However, these authors identified these worms and their clamps as being from G. bivaginalis, and also identified material comprising mostly Cathucotyle cathuaui (and some true G. acanthura) as G. secunda. Kohn et al (1971) recorded male copulatory organs longer than in the present studyup to 275 µmfor worms from Pomatomus saltatrix in the Atlantic. This was despite the fact that these worms were relatively small (maximum size 4170).…”

New data on some species of Monogenea and Digenea parasites of marine fish from the coast of the State of Rio de Janeiro, Brazil

“…Remarks: Kohn et al (1971) described Gotocotyla travassosi in Pomatomus saltator, from Brazil. Subsequently, Lebedev (1984) placed this species in the genus Swakopella.…”
