SOME NOMENCLATURAL CHANGES FOR BLATTODEA AND DICTYONEURIDA (=PALAEODICTOPTERA)Abstract : Three junior homonyms were detected among the genus group names of Blattodea (1) and Dictyoneurida (2) and the following replacement names are proposed: Hongoblatta nom. nov. for Latiblatta Hong, 2002; Hongius nom. nov. for Palaeoneura Hong, 1985 and Mongolianus nom. nov. for Mongolodictya Sinitshenkova, 1992. Accordingly, new combinations are herein proposed for the species currently included in these genus group names respectively: Hongoblatta orientalis (Hong, 2002) comb. nov. and Hongoblatta spinosa (Hong, 2002) comb. nov. from Latiblatta Hong, 2002; Hongius giligonensis (Hong, 1985) comb. nov. from Palaeoneura Hong, 1985 and Mongolianus callidus (Sinitshenkova, 1992) comb. nov. from Mongolodictya Sinitshenkova, 1992. As a result of these nomenclatural changes, a family group name Mongolianidae nom. nov. is also proposed for Mongolodictyidae Sinitshenkova, 1992.
