Revision of the species of Thopeutica Schaum, 1861 from Mindanao (Philippines) (Coleoptera: Cicindelidae)

A revision of all the species of the genus Thopeutica described or cited from the island of Mindanao (Philippines) is presented. Four species are described as new: T. (s. str.) cassolai sp. nov., T. (s. str.) intermedia sp. nov., T. (s. str.) maindai sp. nov. and T. (s. str.) abdita sp. nov. Two new synonymies are established: T. (s. str.) microcephala (Horn, 1924) = T. (s. str.) milanae Wiesner, 1992 syn. nov., and T. (s. str.) davaoensis Cassola & Ward, 2004 = T. (s. str.) anichtchenkoi Wiesner, 2015 syn. nov. In total, 12 species are confirmed for the fauna of this island; the previous citations of 4 other species from Mindanao are discussed and considered erroneous. A key to the species is provided. Color photographs of the habitus, the main diagnostic characters, and the variability of all species are presented.
