Foster, G. A. and Mathis, Wayne Neilsen. 2008. "A review of the Tethininae (Diptera : Canacidae) from the Galapagos Islands." Proceedings of the Entomological Society of Washington, 110, (3) 743–752. https://doi.org/10.4289/07-078.1.
The three known species of the genus Tethina Haliday (T. albula (Loew), T. insulans Curran, and T spinulosa Coe) from the Galapagos Islands are reviewed with an emphasis on structures of the male terminalia, which are illustrated (no males are known for T insulans Curran). Tethina albula and T spinulosa are reported for the first time from the Islands.
