Hi Andrew,
Thanks for bringing this to my attention. While I work on a fix so it doesn't crash Wallace, I recommend downloading your dataset directly from GBIF and using the User-specified module option. You can upload a dataset in .csv format with the first three columns/fields as "scientific_name", "longitude", and "latitude" (in that order). One of the entries for this species is causing the hiccup; it looks like it might not have info for all the qualified fields to be uploaded. From the error message, it looks like some data might have been downloaded to your machine.
