The descriptions were based on shell morphology, anatomy as well as phylogenetic analysis using DNA sequence data of a fragment of the mitochondrial cytochrome oxidase I. All three suits of characters were included into the diagnoses. The new species formed a clade with two species from Lake Towuti, but separate from already known species from Lake Matano. The species were discovered between 2003 and 2005. However, not a single specimen of Sulawesidrobia was found when several sites were revisited in 2018 and 2019. This may be a consequence of the release of South American flowerhorn cichlid fish into the lake, in combination with heavy eutrophication of the once ultra-oligotrophic lake. It seems likely that several populations or even entire species of Sulawesidrobia in Lake Matano may be extinct. The species names given reflect this by acknowledging important conservationists.
