 different genus by Rondani and Becker, named Spathiophora. The colour is grey

 flattened. The head has the forehead nude, antennae short, with third joint 

 pointed, and pai-tly or wholly rufous ; palpi white, with ends dilated and smooth ; 

 oral setae of moderate size ; abdomen long, narrow, with small hypopygium ; wings
