Diaphanogryllacris Karny, 1937

Type species: Gryllacris translucens Serville, 1838

Diagnosis. Tegmen and hind wings transparent without coloration or tegmen partly with a faint yellowish or greyish infumation; veins and veinlets more or less darkened, giving the wings a meshwork like pattern. Media running close to radius in basal fourth to third of tegmen, but never fused, after that both veins separate. Males are characterized by a pair of often long projections from ninth abdominal tergite pointing down and in between a pair of upward projections from tenth abdominal tergite. In few species the pair of projections from ninth tergite is however very short as in D. aequalis ( Walker, 1859) from Sri Lanka, or in D. translucens ( Serville, 1838) from Medan in NHMW, in the latter there is only a very small lobe instead of a projection as in most other species ( Figs 57G, K , arrows).
