Fursch, H. 1987 Neue afrikanische Scymnini-Arten (Coleoptera Coccinellidae) als FreBfeinde von Manihot-Schädlingen. [New African Scymnini-species (Coleoptera Coccinellidae) as predators of Manihot pests.].. Revue de Zoologie Africaine 100(4): 387-394.

Notes: Three new Scymnini-species are described as predators on manihot pests: Nephus phenacoccophagus, Diomus hennesseyi, and Clitostethus neuenschwanderi. Determination is made easier by differential diagnoses and numerous figures. Hosts include Phenacoccus manihoti, P. madeirensis. Chrysomphalus dictyospermi also mentioned.
