Subspecies
Common Names	E: Iven’s Water Skink, Meadow Skink, Iven’s skink
Synonym	Euprepes ivensii BOCAGE 1879 Mabuia ivensii — BOULENGER 1887: 197 Lygosoma ivensii — BOCAGE 1895 Mabuya ivensii — MANACAS 1963 Mabuya ivensi septemlineata LAURENT 1964 Lubuya ivensii — HORTON 1972 Mabuya ivensii — GREER et al. 2000 Euprepis ivensii — MAUSFELD et al. 2002 Trachylepis ivensii — BAUER 2003 Lubuya ivensii — CONRADIE et al. 2016 Labuya ivensii — WEINELL et al. 2019 (in error)
Distribution	Angola, NW Zambia, S Democratic Republic of the Congo (Zaire) Type locality: interior of Benguella, Angola; restricted to “Benguela” by BOULENGER 1887.
Reproduction	Ovoviviparous. Females ovulate tiny eggs and later supply the nutrients for development by placental means.
Types	Holotype: lost, was MB (Museu Bocage) (probably lost in fire 1978) Types: MD (Museu Dundo) [septemlineata]
Diagnosis	Diagnosis (genus): Related to Mabuya, from which it is readily distinguishable by the position of the nostrils on top of the snout, the elongation of the postnasal scale and the extreme elongation of the body (from Horton 1972).
Comment	Synonymy: partly after Horton 1972. Branch and Haagner (1993) synonymized Lubuya with Mabuya but Metallinou et al. 2016 revived it again. Type species: Euprepes ivensii BOCAGE 1879 is the type species of the genus Lubuya HORTON 1972.
Etymology	Named after the collector of the type specimens, Roberto Ivens (b. 12 June 1850, Ponta Delgada, Portugal, d. 28 January 1898, Cruz Quebrada - Dafundo, Portugal). (Glenn Shea, pers. comm., 2 Feb 2024)
