The form of the stridulating field of the male elytra is somewhat characteristic of 

 this genus. In the left elytron it has two transverse veins. In the right elytron it is 

 strongly reticulated, divided by a stout longitudinal vein, and has small hyaline cells. 

 In the females the dorsal field of the right elytron is partly membranaceous within, 

 divided by a strong vein (2nd axillary), which is pectinated with transverse venulse, 

 tomewhat as in Stilpnochlora.
