Population There have been no records since the original collection in the 1860s.
Habitat and Ecology If it is like other members of its genus, it probably occurs near forest waterbodies, and makes foam nests in temporary pools.
Threats If it is a forest-dependent species, then it is likely to be threatened by habitat loss due to agriculture, logging, livestock grazing and human settlement.
Conservation Measures No information is available. Surveys are urgently needed to determine whether or not this species still survives.

Heyer (2000) reviewed the nomenclatural and taxonomic history of the nominal species, re-described the lectotype, and posited that it represents a species of Leptodactylus currently known only from the type specimen. However, Heyer pointed out that this appears to be a juvenile individual, making it unreliable for identifying the species. In view of the lack of records despite surveys over the decades, it is likely that the specimen assigned this name is a misidentification of a syntopic species such as L. vastus or L. natalensis (E. Dias pers. comm. 2021).

Described from two individuals collected in the 1860s; one of which has been lost over the decades. Despite several targeted surveys back to the type locality, there have been no records. However, two congeners occur at and around the type locality: Leptodactylus vastus and L. natalensis, both of which are abundant in suitable habitat in the area (E. Dias pers. comm. 2021).
