New subgenera and species of Agraeciini (Orthoptera, Tettigoniidae, Conocephalinae) from South Asia found in historical insect collections

Based on specimens collected in historical times and stored in the insect collections of the Natural History Museum London and the Zoological Museum Hamburg two new subgenera are established Robustacca subgen. nov. of the genus Peracca Griffini, 1897 and Indoliara subgen. nov. of the genus Liara Redtenbacher, 1891. Five new species are described: Peracca (Robustacca) nigrifrons sp. nov. from Sumatra, Liara (Acanthocoryphus) durata sp. nov. from Hongkong, Liara (Indoliara) dividata sp. nov. from South India, Pseudosubria assamensis sp. nov. from Assam and Depressacca kinabalu sp. nov. from Sabah. The species Odontoconus robustus Karny, 1923 is newly combined as Peracca (Robustacca) robustus (Karny, 1923) comb. nov. An extended and updated key to the subgenera of the genus Peracca Griffini, 1897 is provided. All specimens are deposited in the original collections.
