Rentz, D. C. F. (1975). Two new katydids of the genus Melanonotus from Costa Rica with Comments on their life history strategies (Tettigoniidae pseudophyllinae). Entomological News, 86(7&8): 129-140.
Two new katydids are described from Costa Rica extending the known range of Melanonotus northward. The contrast in life history and morphology between primary forest katydids and secondary growth or temperate species is discussed. The absence of regular nightly stridulation and morphological differences such as the extremely long antennae of the two Melanonotus species and other primary forest epiphyllic katydids are suggested as adaptations to bat predation.
