OK Semitic Women: 
 Big breasts, longer throats (due to the longer jawline). I dont pay attenion to race alot but I confirm those two. 

 Semitic Men: 
 Bigger head to body ratio, longer legs. The hair is average, the Medietterianean Arabized population/city dwellers are more hairier than the desert evolved Bedouins (except nose/ear hair which is a necessity in the desert). Ofcourse this applies more to the minority of the isolated semites.
