Taxonomy & Nomenclature
Synonym/s: Arthroleptides dutoiti Loveridge, 1935
Conservation Status
Missing
Last record: 17 May 1962
IUCN RedList status: Critically Endangered (Possibly Extinct)
Du Toit's torrent frog (Arthroleptides dutoiti) has not been recorded since 1962, and four attempts to relocate the species between 2001 and 2004 have failed. It is therefore listed as 'Critically Endangered' by the IUCN (Lötters et al. 2004). However, an unconfirmed record from the Ugandan side of Mount Elgon in 2003 exists (Pomeroy et al. 2006:3).
