Summary information of 17 populations of L. longiclavatum, including sampling locations and time, host origin, N (sample size), He (genetic diversity), allelic diversity, % polymorphic loci, and IA (index of association).

The null hypothesis of random association of alleles in random mating (IA = 0) was tested by comparing the observed value of the statistic with that obtained after 500 randomization to simulate distribution (* p value *used in manuscript text and figures.
