The taxonomic and nomenclatural history of Lobivia chrysochete (Werdermann) Wessner is reviewed and a lectotype established. Biogeographic, morphological and genetic information is provided to support the assertion that one member of the group, Lobivia chrysochete var. minutiflora Rausch, should be considered a distinct species.

Context 1
... L. chrysochete and L. minutiflora are ap- planate plants with umbilicate centres and can grow to quite sizable specimens of 25-40cm diam- eter (Figures 1 & 2) They both have 20-40 spi- ralling ribs broken into hatchet-shaped tubercles with the areoles placed in the depressions. Each areole carries 8-30 pale yellow to dark brown Table 1. ...
Context 2
... biggest differences are seen in the flowers; those of L. chrysochete are large, flamboyant and campanulate (Figures 3, 5, 7 & 9), with many dark hairs on the receptacle, whilst those of L. minuti- flora are much smaller, almost tubular and carry only a few white hairs (Figure 12). In contrast to L. chrysochete, the exterior of the floral tube of L. minutiflora is bright red (brownish to greenish in L. chrysochete Figure 10, 11 & 12). ...

In contrast to L. chrysochete, the exterior of the floral tube of L. minutiflora is bright red (brownish to greenish in L. chrysochete Figure 10, 11 & 12). These floral characteristics may be consistent with a differ- ence in pollinator preference between the two species, with L. chrysochete flowers being more at- tractive to insects (entomophilous), specifically bees, and those of L. minutiflora potentially better adapted to hummingbirds (ornithophilous). ...
