Diagnosis. Doryodes fulva is most closely related to D. desoto Lafontaine and Sullivan ( Fig. 31 View Figures 26–31 ), which is known from salt marshes along the west coast of Florida and is sympatric with D. fulva in Dixie County. The BOLD database places D. desoto into BIN: BOLD:ACE7229 along with D. fulva . Externally, D. fulva is easily distinguished from D. desoto and the other Doryodes Guenée species with which it flies by the lower margin of the brown forewing line, which is not sharply delineated but blends more gradually into the lower half of the wing than in the other species. Additionally, the hindwing is yellowish beige with brown shading in the postmedial area, whereas it is off-white, light beige, or yellowish white in the other species.

Description. Male antennae bipectinate; head, vertex, and thorax, gray brown; abdomen light beige. Dorsal forewing (male). Forewing length 17–18 mm. Ground color light beige, heavy suffusion of dark brown scales on costa and below dark brown line; yellowish beige area between brown line and costa with very few dark brown scales; distal ⅓ of dark brown line edged ventrally with light beige line bending toward apex; brown line bordered dorsally with white line on proximal ⅔, below which the brown band gradually blends to ground color of wing; orbicular and reniform spots present as minute black dots; fringe light beige. Dorsal hindwing. Ground color light yellowish beige with concolorous fringe; postmedial area with scattered dark brown scales; vein Rs+M1 highlighted with dark brown scales basal to where they split; fringe concolorous with wing. Male genitalia ( Fig. 81 View Figures 79–84 ). Valve trifid apically with costal extension cut away dorsally to form a point on ventral margin; saccular extension drawn to a blunt point terminating short of costal extension; a rounded, fleshy, apical process is situated between costal and saccular extensions; uncus with narrow neck at tegumen, wide basally, arcs downward as it narrows toward pointed apex; vesica with a comb-like sub-basal diverticulum, and two bulbous, spine-like cornuti on right; at end of downward slope, vesica opens to form two small (one unarmed on left and one with apical cornutus on right) and three large diverticula, one on right, one longer one on left, and one elongate, distal diverticulum, each with large, bulbous, thorn-like terminal cornuti; a flat, ventral cornutus is present at junction of downward body of vesica and point where vesica splits into various diverticula. Female genitalia. Unknown.

Type material. Holotype male: USA: Florida: Dixie Co.: Highway 361, 29.564°N, 83.380°W, 16.Nov.2015, J. Troubridge, in the CNC GoogleMaps . Paratypes: 2♂: Dixie Co.: Highway 361, 29.564°N, 83.380°W, 5.Apr.2016, J. Troubridge, 2♂.

Etymology. From Latin, fulva refers to tawny color of this species.

Distribution. This species is known only from the remote Gulf of Mexico salt marshes of Dixie County, Florida.

Remarks. The DNA was analyzed and the 658 COI base pairs compared with those of specimens of D. desoto . The results showed a 0.3% difference between D. fulva and D. desoto , its sister species.
