An Additional Trematode from Tortugas, Florida, and a New Name for Opisthoporus Manter, 1947, Preoccupied

Abstract

Professor Jose M. Ruiz of Sao Paulo, Brazil, has kindly called my attention to the fact that the generic name Opisthoporus Manter, 1947 had been used several times previously, a condition which I had indeed checked but thoughtlessly forgot. For Opisthoporus Manter, 1947 (nec Opisthoporus Benson, 1851; Opisthoporus Minot, 1877; Opisthoporus Fukui, 1929), the name Postporus is proposed. The two species become Postporus epinepheli (Manter, 1947) and Postporus mycteropercae (Manter, 1947). The combination Pleurogonus candidulus (Linton, 1910) (misspelled candibulus in my paper) had been made in 1946 by Ruiz (1946: 295) where, however, it was first printed candulus. Its correct name is, therefore, Pleurogonius candidulus (Linton, 1910) Ruiz, 1946. The author's report on trematodes of marine fishes of Tortugas, Florida (Manter, 1947) refers (p. 258) to a few species not described because they were represented by single specimens deemed inadequate for satisfactory identification. One of these has since been studied in the light of Dollfus' (1946) description of some interesting trematodes from Kyphosus sectatrix from Dakar, Africa. It is a spiny distome from a related host (Kyphosus incisor) and is closely related to Cadentella ccdenati (Dollfus, 1946) Nagaty, 1948. As Nagaty (1948) has noted, Enenterum pseudaureum Dollfus, 1946 from Kyphosus sectatrix at Dakar, Africa is a synonym of Enenterum pimelepteri Nagaty, 1942 from tahmel in the Red Sea. The host genus Pimelepterus Lacapede, 1802 is listed as a synonym of Kyphosus by Jordan, Evermann and Clark (1930). Nagaty's spelling pimelopteri seems to be from Pimelopterus of Schinz, 1822 apparently a misspelling of lPimelepterus. Cadenatella americana n. sp.
