Lymanbensonia in Cact. Succ. J. (Los Angeles) 56: 101. 1984 sec. Korotkova & al. (2010)
- Type: Lymanbensonia micrantha
Segregated from Acanthorhipsalis (Kimnach 1984), but otherwise either assigned to Lepismium (Barthlott 1987; Barthlott & Taylor 1995; Anderson 2001, 2005) or to Pfeiffera (Hunt 2006). The molecular phylogenetic study of Korotkova & al. (2010) unexpectedly found the three species now assigned to Lymanbensonia to represent a highly supported isolated clade distant from either Lepismium or Pfeiffera. As this new clade contained the nomenclatural type of Lymanbensonia, this generic name was reinstated.
