“…Most of the taxonomic descriptions of the cymothoids are based primarily on ovigerous females; the various life cycle stages (excepting perhaps the premanca/manca of few Cymothoa sp.) have not received much attention thus far (Richardson 1905;Sartor and Pires 1988;Thatcher et al 2003Thatcher et al , 2007Trilles and Bariche 2006;Hadfield et al 2011). Keeping these in view, the present paper addresses the question of precise identification of the cymothoid C. frontalis infesting the belonid fish inhabiting the Malabar Coast.…”

Background: Cymothoa frontalis Milne Edward, 1840 is a very poorly described cymothoid, notwithstanding the previous redescription of the female. Pertinently, to date, the host of C. frontalis has not been identified with adequate precision. Most of the descriptions of cymothoids carried out hitherto were based primarily on females, but practically ignoring other life cycle stages. The present paper redescribes the female and describes other life cycle stages of the species C. frontalis to get better precision in their identification. Results:The female phase of C. frontalis is redescribed according to type specimens extant in the NMNH, Paris, and also by the data obtained from live specimens collected during the present study. The general morphology and appendages of various life cycle stages of the species are described. Among 80 fish species from 35 families examined, C. frontalis was recovered only from Strongylura strongylura signifying its oligoxenous host specificity, the prevalence and intensity being 68.65% and 1.9, respectively. Each host fish in more than 85% of the population was infested with a pair of C. frontalis, in three combinations, predominantly with male-female pair (70.9%). C. frontalis exhibited strict site specificity attaching to the buccal cavity of the host fish. The study has also identified three major phases (marsupial, free living and infective) in the life cycle of C. frontalis. The zygotic-staged marsupiumites were developed through five sequential ontogenetic stages. The manca released from the marsupium become infective after a brief period of free swimming life. During the infective phase, C. frontalis completes remaining life cycle stages with successive moulting. Further, six successive stages of the ovigerous females have also been identified. Conclusions: The present redescription of the female and the description of transitional, male, juvenile and larvae of C. frontalis facilitate precise identification of the species at any stage of the life cycle. Further, the strict host and site specificities of the parasite, as borne out from the present study, and its high degree of prevalence in the host make C. frontalis as an ideal model organism to study the strategies to be adopted for the management of parasites infesting edible fishes.

“…Interest in eastern Mediterranean cymothoids has increased in the last decade and about 20 species have been confirmed along the Levantine basin to date (Horton 2000;Öktener and Trilles 2004;Bariche and Trilles 2005, 2008Horton et al 2005;Trilles and Bariche 2006). The situation is similar along the Mediterranean coasts of Africa, where various cymothoid species have recently been identified as well.…”

“…The cymothoid fauna of the entire area can be considered largely understudied, particularly along the southeastern Mediterranean coast where introduced species prosper. So far three exotic cymothoids, namely Cymothoa indica Schioedte et Meinert, 1884, and Anilocra pilchardi , both Lessepsian migrants, and Ceratothoa collaris Schioedte et Meinert, 1883, an exotic from the Atlantic Ocean, have been recorded from Lebanon Trilles 2006, 2008;Trilles and Bariche 2006).…”

This paper presents the first record of two native Mediterranean cymothoid species caught attached to introduced Lessepsian rabbitfishes. This is also the first record of cymothoids from the coastal waters of Libya. Anilocra physodes was collected from Siganus luridus while Nerocila bivittata was found on both Siganus rivulatus and S. luridus. Rabbitfishes in the southern central Mediterranean have acquired native Mediterranean cymothoids but do not seem to be infested along the Levantine coast.

Mothocya renardi (Bleeker, 1857), a protandrically hermaphroditic cymothoid, parasitising the banded needle fish Strongylura leiura (Bleeker) from the Malabar Coast, India is redescribed and morphological data for different life-cycle stages [male, transitional and ovigerous female, larvae (pre-manca and manca) and juvenile] are provided. Mothocya renardi exhibited strict oligoxenous host specificity by infesting only S. leiura and showed high prevalence levels (reaching up to 92%). The life-cycle of M. renardi comprises three major phases (marsupial phase, free living phase and infestive phase). The marsupial phase comprised one zygotic, three embryonic and two larval stages, all of which remained in the marsupium until the final staged manca is released into the surrounding water. After having led a short free- swimming life, the manca infested the branchial cavity of the host fish, S. leiura. Subsequently it was transformed successively into juvenile, male, transitional and finally functional female through biphasic moult which occurs in between each stage. Based on the presence (or absence) of a brood pouch and/or marsupiumites, six successive stages of the female population were also identified. These data will help precise identification of the female M. renardi irrespective of their stage. The present paper also discusses the host-parasite interactions between S. leiura and M. renardi.
