Study of the male of Photopsis galapagensis Williams confirms that this species should be placed in Sphaeropthalma Blake and is allied with the tropical species of this genus. This species is best placed in the S. anthophorae species-group sensu Schuster (1958). Important details concerning male morphology are discussed. The female is also described and illustrated for the first time. Fully winged males of Morsyma ashmeadii Fox, which is a species previously known from apterous individuals, are discussed. Caenotilla Pitts and Manley is a junior synonym of Morsyma and C. choreocarina Pitts and Manley is a junior synonym of Morsyma ashmeadii Fox.
