Despite being one of the most conspicuous African opilionids, the members of Lacurbsinae remain one of the least known groups of harvestmen species. All eight previously-known species of Lacurbsinae are inadequately described and poorly illustrated, leaving the morphological characteristics of this subfamily obscure. After more than half a century, we describe a new species of Lacurbsinae. Metalacurbs foordisp. nov. is described, based on a male specimen collected in Ankasa National Park, Ghana, with a detailed description and illustration of its external and genital morphology. This marks the first modern taxonomic description of a species within Lacurbsinae, including an illustration and description of the male genital morphology, a crucial modern taxonomic characteristic for Opiliones and represents a starting point for the taxonomic revision of the subfamily.
