AbstractThe genus Pyrgodera is easily recognised amongst Old World genera of the subfamily Oedipodinae, to which it belongs. by its exceedingly high, arched, laminate pronotal crest with acute anterior angle, partly covering the occiput. There is only one species, Pyrgodera armata (F. W.), in the genus and there are no described subspecies or races. It is widely distributed over the plains of Western Asia, with the exception of the Arabian Peninsula. It inhabits alluvial plains and adjoining hills with clay or stony soils (Uvarov, 1927). There appears to be only one generation a year and there is an egg diapause in winter. The hoppers are normally of uniform green or buff colour and are easily distinguishable from most other Acridid nymphs by their enormous ,crests.
