*black horizontal stripes on sides *bulkier deep body compared to M. saxatilis
*black horizontal stripes on sides with lower stripes broken and shifted *second anal spine nearly as long as third *lower and upper jaws even
*black horizontal stripes on sides, usually continuous *body more elongate and less deep than M. chrysops
*5-7 spines in anal fin *dark mottling on body
*7-9 spines in anal fin *dark suborbital bar or tear drop
*extremely small *9-12 dark vertical bars
*opercular lobe black, fleshy, and lacking pale border *vermiculations on preorbital area and cheek
*opercular lobe black with pale margin and bony to edge *mouth large with the maxilla extending well beyond anterior rim of eye -vermiculation on head
*light bars radiating from the opercle *looks a lot like Ambloplites but has 3 anal fin spines
*long pectoral fins that are moderately to sharply pointed and will reach past anterior margin of the eye when depressed anteriorly *opercular lobe completely black and fleshy to its margin *dorsal fin with dusky spot in posterior base, but not always
*opercular lobe dark and fleshy with white margin on its tip *mouth small -vermiculations on the cheeks and opercles
*opercular lobe bony to margin with a white dot on posterior margin (often concave) that is red in life *long and sharply pointed pectoral fins that extend well past anterior margin of eye and over dorsum if depressed anteriorly or dorsally, respectively
*pale spots on body (red in life) and cheeks with dark colored spots opercular lobe stiff to its margin *no vermiculations on cheeks -pale spot at anterior end of lateral line
*bronze coloration with dark blotches or vertical bars on sides *dorsal spines nearly equal in height
*wide back lateral stripe or nearly confluent blotches *lines of dark pigment spots on the lower sides *dorsal spines nearly equal in height
*wide black lateral stripe or nearly confluent blotches *tallest dorsal spine more than twice height of the shortest *few scattered flecks of dark pigment on the lower sides
*vertical bars on the sides *anal fin with 6-7 spines *length of dorsal fin base is less than the distance from the origin of the dorsal fin to the middle of the eye
*lacks vertical bars on the sides *anal fin with 6-7 spines *length of dorsal fin base is equal to the distance from the origin of the dorsal fin to the middle of the eye
*body very slender *color pallid or translucent with little dark pigment *1 anal spine *belly lacking scales
*frog face *"W" or "U" shaped markings on sides *dorsum with 6-7 saddles
*frog face *4 distinct dorsal saddles diagonally oriented *first saddle distinctly before first dorsal fin
*8-10 dorsal saddles *about 10 midlateral dark blotches *lateral line incomplete -has red in the anal fin
*blunt, round nose *preorbital bar continuous around snout *suborbital bar typically present
*dusky streaks slanting posteriorly (looks like smeared graphite) *males with dorsal fins that are greatly elongated *horizontal rows of spots on the dorsum -one of the most distinct darters and probably of hybrid origin
*dark pigment at base of spinous dorsal fin *striations in caudal fin *gill membranes broadly joined where E. kennicotti has narrowly joined gill membranes
*very small *highly arches lateral line anteriorly with only 2-3 scales between lateral line and dorsal fin
*pair of fused blotches at the caudal fin base in the form of a "filled in B" *lots of dark pigment in blotches on the sides *6 dorsal saddles
*6 hourglass shaped dorsal saddles
*clear at base of dorsal fin with a median dark streak, no dark pigment at base of spinous dorsal fin, a lot like E. flabellare *dark humeral spot present *caudal fin with vertical stripes
*dorsum with 6 evenly spaces saddles *a series of "W" "M" or "X" shaped midlateral markings *preorbital bars present that are not continuous around snout *anal fin with 1 weak spine
*3 distinct basicaudal spots *narrowly connected gill membrane *dorsal rays in breeding males develop egg knobs
*short snout *pale lateral line scales *distinct vertical column of dots on caudal peduncle
*small *really long pelvic fins and a row of rectangular blotches along sides
*blunt nose *8-9 dorsal saddles with the first one touching the posterior of head
*6 dorsal saddles *obvious pale spot just posterior to head and anterior to first saddle
*gill membranes narrowly connected *sides also with 10-12 horizontal stripes *dark humeral spot present *oblique pale bar bordered by black is present on the cheek
*6 dorsal saddles *around 10 vertical bars on sides that extend onto belly
*all median fins with pale submarginal band and dark marginal band *no white basicaudal spots -sides with fine horizontal lines
*smallest Nothonotus with distinct saddles just posterior to head and anterior to caudal fin *no horizontal lines like other Nothonotus
*dark horizontal markings on cheek, often forming two spots *large pair of white basicaudal spots present, often in hourglass shape *all median fins with pale submarginal band and dark marginal band
*median fins with dark marginal bands and NO pale submarginal bands -fine horizontal lines on sides
*distinct dorsal fins *thick bands vertically -it looks like a perch
*dark midlateral band or row of blotches *rows of black spots along dorsum
*many dorsal saddles with larger blotches on sides than P. caprodes *circles on dorsum (look like cheerios) *pig-like snout
*many dorsal saddles *midlateral blotches smaller than in P. burtoni *pig-like snout
*suborbital bar usually prominent *midlateral blotches becoming shorter and wider posteriorly
*head long *sides with 8-14 fused blotches *suborbital bar in shape of sickle
