By original designation. Diagnosis. Nemia can be readily separated from the genera Nemopterella , Siccanda and Afroptera by at least four key features: the apical antennal segment ends in a short sharp tooth-like point (not membranous); males lack abdominal pleuritocavae; the thorax and abdomen are characteristically striped, and the costal cells have dark marks on the membrane. For full description of the genus, see Tjeder 1967: 438 .
