Holotype: ISER (no reference number) female 84.9mm SL. Paratype: ISSB 3119 female 66.3mm SL.
Type locality: Grieta Punta de Guana, Matanzas Province, Cuba (23o04’N, 81o35’W). It may coexist at this site with Lucifuga dentatus (Nalbant 1981:189). Known also from Cueva de la Pluma, Matanzas Province and Cueva del Tunel, Habana Province (Diaz Perez, Lima and Machado 1987). See also Garcia Debras, Gonzalez and Yager (1999).

See the discussion of the phylogenetics and distribution of the genus Lucifuga under Lucifuga subterranea.
Lucifuga simile has a highly restricted distribution. It is only known to occur in two closely located caves in the Northwest Matanzas province of Cuba. Caves are frequently connected underground by water, and both of these caves are exposed to similar threats, therefore, a single location is suspected for this species. Although data are limited, the population size of L. simile is potentially small and it may have a long generation length. The characteristic low levels of oxygen within these caves is another significant limiting factor.
Threats to cave-dwelling species in the Caribbean include habitat degradation through rock removal or siltation, hydrological manipulations caused by water removal, environmental pollution, and the introduction of alien species. Typically, a cave that is near high densities of human populations is more threatened. The main threat to L. simile is habitat degradation by human activities (continuing decline in habitat quality for this species is suspected). In particular, the Grieta Punta de Guana, which has historically had a larger abundance of L. simile, is at risk due to negative impacts from an oil well operation that is blocking its entrance.
The widespread introduction of alien species into these cave systems are likely negatively impacting the populations of L. simile through competition or predation. Both Cueva La Pluma and Grieta Punta de Guana are located within Ecological Reserve Bacunayagua, which is listed by the IUCN as a National Park (category II). Additionally, Cueva La Pluma is a Relevan Natural Site and is listed as a natural outstanding element. The level of protection these conservation measures specifically offer L. simile is questionable.
The Cuban Red List (2012) listed L. simile as Critically Endangered (CR A2ce; B1+B2ab), based on its low reproductive rate, possible longevity, declines in habitat quality, effects from introduced species, and small EOO and AOO. Further research on population size is needed. Lucifuga simile is assessed for The IUCN Red List as Critically Endangered under criterion B (CR B2ab(iii)). (Dooley, J., Collette, B., Aiken, K.A., Marechal, J. & Pina Amargos, F. 2015. Lucifuga simile.

Alfredo Garcia Debras (pers. comm.) reports that some historical locations for this species have been partially or totally destroyed, some are affected by pollution from industrial and /or domestic sources and others by various engineering works. He also states that some marine fish species have been introduced into the habitat of Lucifuga species, where they not only compete for resources (mainly food), but also actively prey on the cave fishes.
