On the Morphology of Mekong Blind Sole Typhlachirus elongatus (Soleidae) with Notes on the Taxonomy of the Genus Typhlachirus


The morphological description of a rare species, Mekong blind sole Typhlachirus elongatus, from the Mekong River delta is described. Three species—T. lipophthalmus, T. caecus, and T. elongates—are considered as species included in the genus Typhlachirus. Unfoundedness of placing T. elongatus in the genus of Brachirus is shown.
