Abstract

The genera Rhammatopoda Redtenbacher, 1892 (Mecopodinae), Gnathoclita Hagenbach, 1841 (Pleminiinae), Theia Brunner-Wattenwyl, 1891, Viadana Walker, 1869, Tomeophera Brunner-Wattenwyl, 1878, Abrodiaeta Brunner-Wattenwyl, 1878, Aganacris Walker, 1871, Theudoria Stål, 1874, Ligocatinus Rehn, 1901, gen. resurr. (it is restored from synonym to Homotoicha Brunner-Wattenwyl, 1891), Ceraiaella Hebard, 1933, Enthephippion Bruner, 1915, Parableta Brunner-Wattenwyl, 1878, Chloroscirtus Saussure et Pictet, 1897 and Euthyrrachis Brunner-Wattenwyl, 1878 (Phaneropterinae), as well as Phlugiola Karny, 1907 (Meconematinae) are considered. The following new taxa are described from Peru, Ecuador, Brazil, Bolivia, Surinam, Paraguay and Colombia: Rhammatopoda calabaza sp. nov. from Peru; Rh. oxapampa sp. nov. from Peru; Gnathoclita (Gnathoclita) izerskyi sp. nov. from Peru; Theia (Oxyprorella) hetairomima sp. nov. from Peru; Viadana (Paraviadana) ashaninka sp. nov. from Peru; V. (Viadana) rostrata sp. nov. from Peru; V. (V.) parobliqua sp. nov. from Ecuador; Tomeophera cellulata sp. nov. from Peru; T. para­llela sp. nov. from Peru; Abrodiaeta (Abrodiaeta) macricula sp. nov. from Peru; A. (Sclerodiaeta) propinqua subgen. et sp. nov. from Brazil; A. (S.) fruhstorferi sp. nov. from Brazil; A. (Barodiaeta) minasgerais subgen. et sp. nov. from Brazil; Rostellula minutissima gen. et sp. nov. from Peru; R. santacruzi sp. nov. from Bolivia; Separatula adunca gen. et sp. nov. from Peru and Ecuador; Theudoria (Ctenophorema stat. nov.)pyrrhopterus surinam subsp. nov. from Surinam; Ligocatinus paraguay sp. nov. from Paraguay; Ceraiaellazebrina pudica subsp. nov. from Peru; Stylibleta subgen. nov. and Oscarbleta subgen. nov. in Parableta s. l.; P. (Parableta)cercata sp. nov. from Ecuador; P. (P.) nikolaii sp. nov. from Peru; P. (?P.) denticulata sp. nov. from Bolivia; Chloroscirtuscolumbianus sp. nov. from Colombia; Euthyrrhachis consobrina elsol subsp. nov. from Bolivia; Phlugiola paratushali sp. nov. from Peru. One former genus is reduced to the subgenus Homotoicha Brunner-Wattenwyl, 1891, stat. nov. of the genus Theudoria. Amaura olivacea Brunner-Wattenwyl, 1891, A. borelli Giglio-Tos, 1897, Ligocatinus sordidus Rehn, 1921, L. minutus Rehn, 1921 and Phaneroptera quadrivittata Piza, 1967, considered previously as belonging to three species of Homotoicha, as well as Phaneropterella infumata Piza, 1977 are transferred to the genus Enthephippion with establishing the following synonymy: Phaneropterella Piza, 1977, syn. nov. = Enthephippion; E. olivaceum comb. nov. = Ph. quadrivittata; E. borelli sp. resurr. et comb. nov. (it is restored from synonymy to E. olivaceum) = L. sordidus syn. nov.; E. minutum comb. nov. and E. infumatum comb. nov. are possible synonyms of each other. Homotoicha amazoniensis Cadena-Castañeda, 2015 is here included in the genus Euthyrrhachis (as E. amazoniensis comb. nov.). Some other new data on the above-mentioned genera are also given.
