standing out from the sides of the cephalothorax. Pedicle 

 short. Lip longer than wide. Sternum large, pointed in

Semora is near Sjaiageles and Keyserlingella, but the 

 cephalic part occupies less than half of the cephalothorax; 

 moreover, it is lower and flatter than Keyserlingella, and not 

 so long and narrow as Synageles, from which latter genus it 

 also differs in having the quadrangle of the eyes wider than 

 long.
