Conservation status in Cameroon.

Lepidagathis alopecuroides   is not listed on http://www.iucnredlist.org nor in Onana and Cheek (2011). The extent of occurrence of this species is estimated at 124,600 km2 and has an area of occupancy of about 20 km2. The taxon is currently known from five localities. Construction of dams are in progress at two sites for this species: a hydroelectric dam at Natchigal on the Sanaga River; and another on the Dja River, and if fully operational the habitat of L. alopecuroides   may be destroyed. Based on these threats, and the fact that the species is only known from five localities, L. alopecuroides   is here assessed as Endangered. IUCN Red List Category: Endangered ENB2ab (ii, iii).
