S: Saibal Senguptas Collection, Guwahati, Assam RESULTS Statistics Visual inspection of the data suggested a striking differ- entiation between specimens from Assam (NE India) and Northwest Myanmar on the one hand and specimens from the remainder of Myanmar on the other hand. One phe- notype was characterized by a high number of ventral counts, an undivided anal shield and usually two anteri- or temporal shields whereas the other was characterized by a low number of ventrals, a divided anal shield and usu- ally one anterior temporal shield. These characters were included in a PCA. The first component explained 92% of the total variance. This demonstrates that these char- acters covary strongly and thus form a suite of characters that sharply differentiates between the two phenotypes. The individual scores on this component were plotted U 0- 45' 16 94 Situde 93 92 28 Fig. 1.
