Monogeneans from Pangasiidae (Siluriformes) in Southeast Asia: IV. Five new species ofThaparocleidusJain, 1952 (Ancylodiscoididae) fromPangasius krempfi,P. kunyit,P. mekongensisandP. sabahensis

A description of two new species of Ligophorus Euzet & Suriano, (Monogenea: Ancyrocephalidae) from Malaysian mugilid fish using principal component analysis and numerical taxonomy

“…14. Fenestration in anchors is not limited to these Ligophorus species or to any particular group of monogeneans and can be found in species from different genera, such as in most Thaparocleidus species from pangassids (single fenestrum in ventral anchors) (see Pariselle et al , 2001a, b, 2002, 2003, 2004, 2005a, b, 2006) and in Haliotrema banana Lim & Justine, 2007 (single fenestrum in dorsal and ventral anchors) (see Lim & Justine, 2007). The occurrences of fenestrated anchors in a few species of unrelated genera seem to suggest that fenestration in anchors is of specific importance rather than generic importance in monogeneans.…”

Monogeneans from Pangasiidae (Siluriformes) in Southeast Asia: X. Six new species of Thaparocleidus Jain, 1952 (Ancylodiscoididae) fromPangasius micronema

“…As all the parasitic species from P. micronema quoted in this paper were recorded from all the locations (North and South Borneo, Central Sumatra) without evidence of morphometrical differences; we may conclude that the isolation of host populations is not ancient (Isolation of host populations is effective as P. micronema is strictly from freshwater and as rivers from North and South Borneo are not connected). Otherwise, we would probably have found differences among parasitic populations (see "Conclusions" in Pariselle et al, 2002b). The present six new species bring the number of monogenean parasitic species described on 19 species of pangasiids (P. bocourti, P. djambal, P. elongatus, P. gigas, P. humeralis, P. hypophthalmus, P. kinabatanganensis, P. krempfi, P. kunyit, P. lithostoma, P. mahakamensis, P. mekongensis, P. micronema, P. nasutus, P. nieuwenhuisii, P. pangasius, P. polyuranodon, P. rheophilus and P. sabahensis) to 46.…”

Monogenoidea en Serrasalmus rhombeus (Linnaeus, 1766) de la Cuenca Amazónica Boliviana

“…Ya que existen especies de parásitos que se encuentran solamente en «poblaciones» del huésped, y como lo demuestran Pariselle et al (2002), podría deberse a la existencia de un complejo de especies o de poblaciones aisladas identifi cadas como de S. rhombeus. Aún mas la diversidad de estas especies de parásitos es tan elevada entre las poblaciones de huésped, por lo que la existencia de un complejo de especies es muy probable.…”
