Etymology
The first letters of the generic name Tenui- are derived from the Latin word “tenuis”, meaning “thin” or “sharp”. The last letters -cornus of the generic name are derived from the Latin word “cornus”, meaning “horn”. The generic name is male in gender and refers to the thin inner antennal process.
