Diagnosis. Pyreferra slotteni is most closely related to Pyreferra pettiti (Grote) (BIN: BOLD:AAD2999) ( Fig. 54 View Figures 49–54 ). They can be distinguished from each other by the forewing of P. slotteni , which is slightly more pointed than that of P. pettiti , and by the medial and postmedial lines, which are slightly wavy in P. pettiti , but straight or slightly curved in P. slotteni . Internally, among many differences, the clasper of P. slotteni is about twice as wide as that of P. pettiti , and the apex of the left valve is evenly rounded in P. slotteni , but shorter with a jagged tip in that of P. pettiti ( Fig. 103 View Figures 100–104 versus 104). The DNA of P. slotteni was analyzed and the 658 COI base pairs compared with those of specimens of P. pettiti . The results showed a 5.77% difference between P. slotteni and P. pettiti .

Description. Antennae filiform, ciliate; head, vertex, thorax, and abdomen orange. Dorsal forewing (both sexes). Forewing length 14–15 mm. Ground color orange; antemedial, medial, and postmedial lines dark orange, straight or slightly curving, not wavy; thin terminal line dark orange brown; veins highlighted with scattered gray scales, becoming darker gray spots on postmedial line; scattered light-gray scales present between cubital cell and costa; orbicular and reniform spots delineated by light orange scales, reniform spot with dark-gray scales in posterior half; fringe orange. Dorsal hindwing. Ground color light orange yellow, lightly suffused with maroon scales between medial line and margin; medial line of scattered maroon scales, terminal line maroon; faint discal lunule light orange; fringe light orange yellow. Male genitalia ( Fig. 103 View Figures 100–104 ). Base of valves with dorsal processes arising from sacculus on either side of juxta; a low process arises from costa adjacent to tegumen; clasper relatively wide, bends ventrally at right angles below apex, (resembling a sock) extends to apex of left valve and beyond apex of right valve; a membranous area connects sacculus to sclerotized valve tip, where costa narrows and bends ventrally to form a finger-like apex on left valve; tip of right valve shorter than that of left valve and is divided into a short dorsal process and longer ventral process; juxta wide at base, with a narrow neck that widens toward aedeagus; sclerotized plates extend from ventral corners of tegumen to meet above aedeagus; uncus curves gently downward to blunt tip; vesica bends downward and backward, with a small diverticulum on left at point where vesica turns backward; a small diverticulum on right is present mid-way along vesica and covered with a dense field of fine cornuti, and a large, dorsal, subapical diverticulum is present above ductus seminalis. Female genitalia. ( Fig. 138 View Figures 132–138 ). Ovipositor lobes setose; ostium bursae and ductus bursae well sclerotized; ductus bursae folds to the left below ostium bursae and then bends to the right where it meets orbicular appendix bursae; appendix bursae arises from ductus bursae where ductus bursae meets globular corpus bursae; corpus bursae with three elogate signa.

Etymology. I take pleasure in naming this species for Dr. Jeffery Slotten, who collected the holotype.

Distribution. Pyreferra slotteni occurs from northern Florida, northward at least to North Carolina, where it flies with P. pettiti .
