Theope Revisited: A Synopsis of New Discoveries, with the Description of Three New Species (Lepidoptera: Riodinidae: Nymphidiini)

Since the last revision of the Neotropical riodinid genus Theope Doubleday in 1999, several new Amazonian species have been discovered. These discoveries are summarized here. Two new species were described between 2002 and 2006, T. fayneli Gallard (nycteis group) and T. minialba Gallard (miscellaneous group), and an additional three new species are described here, T. tetrastigmoides Hall (tetrastigma group), T. harrisi Hall (hypoleuca group), and T. euselasina Hall (eurygonina group). The genus Theope now contains 73 species and, with the proposal of the eurygonina group for T. eurygonina Bates and T. euselasina, fifteen species groups. The recently proposed subspecies name minimus Gallard is here synonymized with T. fayneli (n. syn.).
