A new species of cypriniform fish has been described from the Irrawaddy River drainage in Myanmar.
Named Psilorhynchus breviminor by Kevin Conway and Richard Mayden in the latest issue of Ichthyological Exploration of Freshwaters, the new species is distinguished from congeners by a combination of fin-ray and scale counts, proportional measurements and differences in the sensory canals in the head.
The species is named for its short, stout appearance (Latin brevis, meaning short and minor, meaning small) and was collected from a cool, fast flowing stream that was about 30 cm deep.
The stream has a substrate of sand and gravel, and the pH of the water was 8.4.
