Discussion. TSD collected the Fuchs Hammock specimens, and H. Neunzig identified them as “ Cabotia sp. ” in 1987. They will be published in a forthcoming Moths of North America fascicle. More recently, a female was collected by a FDACS-DPI plant inspector at a residence in Miami in March 2013, and the next month, JEH collected a male and females at the University of Florida’s Tropical Research and Education Center in Homestead.

Cabotia Ragonot, 1888 is widespread in the Caribbean and South America; its type species, C. semidiscella Ragonot, 1888 , is Argentine. Heinrich (1956) notes that the differences among the species are slight and that some of the names may be conspecific. We identify ours as A. (C.) bonhoti based on proximity to the type locality in the Bahamas, and the genitalia of the single male are like those illustrated by Heinrich (1956). The New World species of Cabotia can be characterized by the fusion of some of the thumbtack-shaped signa into a line, but the distribution of the unfused signa seems to follow no consistent pattern.

Roesler (1973) revised Cabotia to a subgenus of Ancylosis Zeller, 1839 . We provisionally follow this classification because it reflects many shared characters of venation and genitalia, including stalked forewing Rs 2 and Rs 3, hind wing M 2 and M 3 fused entirely and stalked with CuA 1, the generally similar male genitalia, and the corpus bursae with numerous tack-shaped signa. However, Roesler’s description of Cabotia does not agree in certain key characters with Heinrich’s (1956) nor with our specimens, and it may be questioned whether the Palaearctic species placed in Ancylosis (Cabotia) are monophyletic with the New World ones. The male antennae of New World Cabotia do have a distinct sinus, the male maxillary palpi are brush-like and nest inside a groove in the labial palpi, which are porrect, and each valva has a clasper near the base. Roesler’s descriptions of Ancylosis and Cabotia accordingly need revision. Nevertheless, subgenera are useful for reflecting the unity of and divisions within the genus.
