Leucania incognita (Barnes and McDunnough)

Cirphis incognita Barnes and McDunnough 1918 (Type)


Texas Population: Male forewing dirty light brown. A dark streak runs from the base of the wing to the discal dot and just beyond. Discal dot a black spot accented with white. Postmedial line represented by a curved line of indistinct dark brown dots. A series of black spots along the apical (outer) margin of the wing. Hindwing white with a series of black dots around the outer margin. Female similar to the male, but more washed out and with the markings typically more vague, particularly the dark line from the base to the discal dot.

Florida and Antillies Populations: Forewing a rich, dark brown. A dark, prominent dash runs from the base of the wing to the discal dot and between the discal dot and the postmedial line. Discal dot a short white line. Postmedial line consisting of prominent dark dots, sometimes connected into a dentate line. Dots along apical (outer) margin of the wing present, but vague. Hindwing white with a series of dark dots along the outer margin.

Distribution (See maps below): Leucania incognita is primarily known from southern and central Texas, but the species has been collected from as far west and southern Arizona. In the east this species occurs in Florida. The species is also known to occur in Mexico, Central America, and the Antilles.

Identification Quality: Excellent. However the two principal North American populations are significantly different in superficial appearance, although there are no significant differences between the male genitalia of the two populations. The relationship between these two populations must be sought in the tropical distribution of the species.

Similar Species: This species is easily separated from all other North American species by its brown coloration with the dark streak through the center of the wing and the white hindwing with the small black dots along the outer margin.
