American ichthyologists John Switzer and Robert Wood have described a new species of darter from the Meramec River drainage in Missouri.
Naming the new species the Meramec Saddled Darter (Etheostoma erythrozonum) in a recent issue of the journal Zootaxa, the authors assign it to the subgenus Poecilichthys and distinguish it from other members of the subgenus by the presence of 4 dark saddles on back and upper sides, scales on breast, the absence of blue on the body, and prominent red-orange blotches on the body.
This speies is named for the red-orange stripe and blotches on the body (Greek erythros=red and zona=girdle).
