Thyrocopa leonina Walsingham, 1907b: 505 , plate 15, fig. 3.

Lectotype: UNITED STATES: HAWAII: Lanai: 2000’ [610 m]: 1 3 (slide 4078 BMNH), Feb 1894, Perkins (BMNH), designated by Zimmerman, 1978: figs. 660, 676 (as “ holotype ”).

Thyrocopa leonina Walsingham ; Zimmerman, 1978: 988, figs. 660, 676.

Diagnosis: Thyrocopa leonina can be separated from the other Lanai Thyrocopa by the absence of a dorsal ridge on the uncus (present in T. abusa ) and by the deeply cleft uncus (unlike T. epicapna ).

Description: Head: Scales rust-brown. Antenna ca. 0.7x forewing length; very dense, short, piliform cilia surrounding male flagellomere; female unknown. Labial palpus brown, third segment ca. 0.6x length of second. Thorax: Brown. Forewing length 9 mm; ground color brown. Hindwing very light brown; fringe very light brown. Abdomen: Mounted on microscope slide. Male genitalia with uncus deeply cleft apically; sacculus short, tapering to sharp apex. Female genitalia unknown.

Food plants: Unknown.

Flight period: The holotype was collected in February.

Distribution: Lanai. Possibly extinct.

Remarks: This species is known only from the holotype collected in 1894. This is (or was) the only Thyrocopa species endemic to Lanai.
