WebI have linked a paper which suggests that 98.7 percent is the usual species cutoff. They do also note "These genetic criteria should always be accompanied by a discriminant phenotypic property". WebRight now there are three levels that you can set with the program, --cutoff_species, --cutoff_family, and --cutoff_phylum. The phylum level cutoff is also used as an ultimate filter for the blast hits percent identity. If you want to only keep sequences that are identified to the species level, just set all cutoffs to '97' or '99'.
