Phylogenetic relationships in the “bicornatum” group of Steinernema based on analysis of D2D3 regions. Steinernema scapterisci and Steinernema nepalense were used as outgroup taxa. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (10,000 replicates) is shown next to the branches. Branch lengths indicate evolutionary distances and are expressed in the units of number of base differences per site
