Chinese ichthyologists have described a new species of minnow belonging to the genus Metzia from the Pearl River drainage in southern China.
Xi Gan, Jia-Hu Lan and E Zhang name the new species Metzia longinasus after its long snout (Latin longus=long and nasus=nose).
The new species, whose description is published in the latest issue of the journal Ichthyological Research, differs from congeners by it upturned mouth, number of lateral-line scales and branched anal-fin rays, long snout and head, and the absence of a longitudinal black band extending along each side of body.
