A new species of the genus Hilethera Uvarov (Oedipodinae: Acrididae: Orthoptera) from Pakistan

The subfamily Oedipodinae has considerable economic importance in Pakistan. It poses constant threat to pastures, orchards and variety of crops in both irrigated and rain-fed areas. Amongst its members, the genus Hilethera has not been studied extensively and it was described by Uvarov in 1925. It comprised two species: Hilethera hierichonica Uvarov and Hilethera aeolopoides Uvarov, but at present, we have added one new species, Hilethera balucha to this genus. This new species is closely related to Trilophidia annulata Thunberg because it has a refined body form but can easily be separated from the same on the following bases: it has the structure of pronotum; its anterior projections are conical, extending outwardly. It has lateral plates with convex median process, has shorter ancorae placed angularly, and has hyaline wings that are transparent with a smoky marginal band, and slightly greenish at the base. This insect has been collected from rocky areas with scattered vegetation that consists of grasses and herbs. H. balocha new species is described from Balochistan Province of Pakistan.   Key words: Oedipodinae, new species, Hilethera Balocha, Balochistan.
