Ergenstrema Labrosi sp.nov. (Monogenea) on The Gills of The Thick-Lipped Grey Mullet Chelon Labrosus at Plymouth

Abstract

Ergenstrema mugilis Paperna, 1964, the only member of the genus, has been collected in the Mediterranean from the gill rakers of the thin-lipped grey mullet Liza ramada (Risso, 1810) by Paperna (1964) and Lambert & Sanfilippo (1977); this parasite, under the name of ‘Dactylogyridea sp.’, was collected also from the same microhabitat of the same host from the coast of Albania by Ergens (1960). At Plymouth, parasites clearly belonging to the genus Ergenstrema have been collected from both the gill rakers and lamellae of a different host, the thick-lipped grey mullet Chelon labrosus (Risso, 1826).
