(Percidae: Etheostoma), with Descriptions of Five New Species

Bulletin 30 NOVEMBER 1, 2012developing tubercles on ventral body scales (vs. lacking);and breeding females having a long tubular genital papilla(vs. rugose, spatulate in Vaillantia and flat, bifurcatein Boleosoma). Species of Doration differ further in developinga pair of small dark spots on the base of the caudalfin (may be obscured in breeding males), a character alsorecognized by Douglas (1974) in E. stigmaeum. This pairof spots is a highly useful field character in distinguishingjuveniles and small adults of Doration from sympatric E.nigrum or E. chlorosoma, which develop a single irregularblotch. However, it is not useful in separating E. stigmaeumfrom E. davisoni, a species that also possesses two smallbasicaudal spots.Species of Doration differ further from those of Vaillantiaand Boleosoma in consistently having two anal spines(vs. 1 in some species). They differ further from speciesof Boleosoma in breeding males developing tubercles onpelvic and anal fin rays. They differ further from speciesof Vaillantia in preorbital bars not meeting at midline.Key to Species of Doration1. Premaxillary frenum present ...........................
