Tuxedo Darter (Etheostoma lemniscatum)

Scientific name: Etheostoma lemniscatum Blanton, 2008

The Tuxedo Darter (Etheostoma lemniscatum) is a freshwater fish of the family Percidae.

Biology

Etheostoma lemniscatum is distinguished from all members of the complex by more posterior positioned anal fin (B6?B8, =332 vs. 317 or less); pectoral fin of nuptial males with dark, distal band confined to rays of the dorsal half or less of fin (vs. across all rays or all but 1?4 ventral rays); and nuptial males with dark and distinctly defined black bands on the distal margin of the caudal, anal, and second dorsal fins (bands more diffuse in other species). Etheostoma lemniscatum is further distinguished from all members of the complex except E. marmorpinnum by higher modal (44 vs. 43 or less) number of lateral scale rows; and intermediate number of pored lateral line scales (26 or 28 vs. 22 in E. percnurum, and 34 in E. sitikuense). From E. marmorpinnum and E. percnurum by intermediate percentage of the first dorsal base area covered by scales (60% vs. 100% in E. marmorpinnum and 20% in E. percnurum); and an intermediate number of scales around caudal peduncle (24 vs. 25 and 23, res
