Etymology. This species was named in honor of Prof. Jeffrey Bell, the person who entrusted R. Gurney with the work with the South African crustacean collection. Type locality. “A water well in the Kroonstad savanna, O. R.C.” (Gurney 1904), Free State, now Republic of South Africa. “This water-hole was a collection of surface-water, quite dry in ordinary weather but field up thundershowers” (Gurney 1904). Type material. Lectotype and paralectotypes were selected by L. Forró and stored in the collection of Natural History Museum (London, United Kingdom), with the accession numbers NHM 1904.9.21.19, NHM 1904.9.21.20– 21 (Forró 1988). Other material examined.
