the three variable loci. The slightly greater differentiation observed 
among tellkampfi populations may be due to the fact that this sub- 
species has a somewhat larger geographic range than any of the 
other three subspecies, or simply to the fact that more populations 
(8) were examined for nominate tellkampfi than for any of the other 
three subspecies. 
Whereas genetic differentiation between infrasubspecific popula- 
tions is slight to moderate, differentiation between subspecies is very 
great (Table 5). At the level of subspecies, variation is observed at 
the EST and PGI loci in addition to the three loci discussed above. 
Significant heterogeneity in allele frequency between subspecies was 
observed at all five loci (Table 5) and overall genetic differentiation 
is very great (Fst = 0.528), with the EST and PGI loci essentially 
fixed for alternative alleles in three of the four subspecies.
