Saxicolella nana   is listed on http://www.iucnredlist.org as Vulnerable ( Ghogue 2010q). Onana and Cheek (2011) assessed this species as Critically Endangered, since at that time it had not been collected since the first collection many years ago. The taxon is endemic to Cameroon and is known from only Nyong River near Mbalmayo. The species was, however, collected again by Kato and associates in 2007. The area of occupancy of this species can be estimated to be less than 20 km2. The extent of occurrence -estimated to be less than 2 km2. The main threat is agricultural activity. The species is here reassessed as Endangered. IUCN Red List Category: Endangered ENB2ab (ii, iii).
