Open encyclopedia reference
Lynchius simmonsi, also known as Simmons' big-headed frog, is a frog species in the family Strabomantidae. It is endemic to southern Ecuador where it is known from the type locality in the Cordillera del Cóndor, Morona-Santiago Province as well as from the adjacent Zamora-Chinchipe Province. Its natural habitat is subtropical old-growth forest. The type series was collected by day on the forest floor. The area was mined during the Cenepa War in 1995, and has consequently seen little human activity, although this may change through a proposed road.
