Remarks. Eukerria saltensis is the second most common earthworm collected in semiaquatic environments, with the native Sparganophilus spp. dominating the communities (Carrera-Martínez, R. unpublished data). As both groups inhabit the same habitats (sandbars, mud, and stream shorelines), it is likely that some competition might be occurring between the native Sparganophilus and the invasive E. saltensis . Furthermore, the presence of E. saltensis raises concern for more rare semiaquatic species, such as those undescribed Sparganophilus species, some members of Diplocardia, and the elusive Lutodrilus in Louisiana. Therefore, there is a need to study and monitor these traditionally neglected semiaquatic earthworm taxa.
