On the taxonomy of the genus Rosacris Bolívar, 1931 (Orthoptera: Tetrigidae)

The genus Rosacris Bolívar, 1931 is a pygmy grasshopper (Orthoptera: Tetrigidae) genus hitherto known only from a holotype male of its type species Rosacris antennata Bolívar, 1931 from Makiling Mt. (Luzon island, the Philippines) and originally assigned to the Discotettiginae. Redescription of the genus and its type species are based on the holotype and a new photographic record of the species (Isarog Mt.) found in Flickr (www.fl ickr.com). The holotype is found to be male nymph rather than an adult animal. The species is morphologically similar to members of the genus Metamazarredia Günther, 1939 from the Philippines. Therefore the genus is transferred from the subfamily Discotettiginae to Metrodorinae. Assumption exists that the specimens hitherto identified as R. antennata represent nymphs of Metamazarredia fuscipes (Stål, 1877).
