Meadow Katydid
This appears to be a common katydid of highland agricultural settings in Kenya. I have found it in small gardens in Nairobi and Eldoret. The color may be brown or green. The males can make noise by stridulating - dragging a hardened ridge on one wing across pegs on the other wing. Females (example below) have a long, sword-like appendage for depositing eggs deep in soil, etc.
