Two new species of hillstream catfish in the Glyptothorax have been described from central Vietnam.
Heok Hee Ng and Jrg Freyhof name the two new species Glyptothorax filicatus and Glyptothorax strabonis in a recent issue of the journal Zootaxa.
Glyptothorax filicatus from the Mekong River drainage in central Vietnam, is distinguished from congeners by the pattern of grooves in its thoracic adhesive apparatus (a patch of skin folds on the chest of the fish) and a combination of proportional measurements of the head and body.
This species is named after the frond-like pattern on its adhesive apparatus (the name is the Latin for adorned with ferns).
Glyptothorax strabonis from the Giang River drainage in central Vietnam, is distinguished from congeners by its small eye, as well as the shape of its thoracic adhesive apparatus and proportional measurements of the head and body.
The species is named after its small eyes (from the Latin meaning one who squints).
