Ushadi, So far as I understand, the basic difference between Senegalia and Vachellia is that in the former, there will be prickles scattered all over the branchlets while the stipules are modified into spines in the latter. Here, the spines that you mention in the link are the characters of Senegalia. Now coming back to the differences between S. catechu (formerly Acacia catechu) and S. polyacantha (formerly Acacia polyacantha), in my opinion, there is none but as per some sources, the main trunk should contain spines in case of polyacantha and this character of difference can be established and elucidated only through field observations on greater areas of distribution of the plants involved.
