First collection thought to be by Thys in 1964 at Ebogo on the Nyong River.

Collected again by Thys in 1973 from Endom & Zoulabot II in the Dja River basin, east Cameroon.

Heinemann & Lenz collected in December 1978/January 1979 in the village of Essangmvout, 35km southeast of Sangmélima & 2kms west of Emvieng (48km southeast of Samgmélima.)

Collected by Grell & Kohler in 1990 3 km east of Minta on the road to Diang. Passaro & Eberl collected in 1994 at Azabiloné. Huijgevoort et al collected in 2000 from 7 km west of Ebebiyin.
Breeding Notes

Reportedly not one of the easier lampeyes. Permanent breeding set ups are considered best. Water incubation of eggs takes 10-14 days. Fry are small & do best on Paramecium as a first food. Growth rate is slow with maturity taking 10 months.
Young are sensitive to water pollution & also sudden changes in pH. Changes should be done very gradually.
