Based on these records, distribution of M. megalophylla was more extensive in the late Quaternary than it is today. Four subspecies recognized.	M. m. megalophylla Peters, 1864 — from SW Arizona and Texas , USA , and Baja California , Mexico , S to W Nicaragua . M. m. carteri J. D. Smith, 1972 — Carchi and Pichincha provinces, N Ecuador , and Lambayeque Department, NW Peru . M. m. intermedia G. S. Miller, 1900 — Netherlands Antilles ( Aruba , Curacao , and Bonaire ). M. m. tumidiceps G. S. Miller, 1902 — coastal and inland localities between C & E Andes ranges of Colombia , Caribbean coast of Venezuela including Margarita I, and Trinidad I.	Head—body ¢.56-73 mm, tail 18-31 mm, ear 13-16 mm, hindfoot 9-14 mm, forearm 50-61 mm; weight 11-22 g.; individuals of subspecies intermedia are smallest (forearm 50-54 mm) and those of subspecies carteri are largest (forearm 56— 61 mm ). Pelage is long and lax. Fur color varies from pale brown to deep cinnamonred; hairs usually have four color bands. Individuals from South American subspecies have cape of long hairs over shoulders, contrasting in color with dorsal fur. Ears are short and rounded. Peters’s Ghostfaced Bat is externally and cranially similar to the Antillean Ghostfaced Bat ( M. blainvillei ) but larger. Skull rostrum is proportionally broader. Braincase is squared in profile, with parietals inflated. Condylo-basal lengths are 13-1-15-1 mm.	Temperate coniferous forest and lowland tropical rainforest to xerophytic scrub. In Ecuador , Peters’s Ghostfaced Bat occurs in cloud forest at elevations of 2350-2700 m. It seems to be more common in hot lowland areas in its northern distribution and in forested areas in tropical regions.	Peters’s Ghostfaced Bat feeds mostly on large moths, usually with body lengths of 5-6 mm; other prey items include beetles and flies.	Female Peters’s Ghost-faced Bats select areas of caves that minimize ventilation and maximize temperature to establish maternity roosts. Male Peters’s Ghostfaced Bats select cooler caves outside mating season. There is evidence that reproductive cycle differs throughout the distribution. Mating season in Venezuela reportedly occurs in March-April. Pregnant females were observed in May and November in Ecuador and February—June in North America. Lactating females were reported in January, March, and October in Ecuador , March on Trinidad Island , and June-August in North America.	Peters’s Ghost-faced Bats usually roost in large and deep cave systems or in abandoned mine shafts. Although they have been observed in roosts with wide ranges of temperatures (over 15°C) and humidity (over 50%), females only use hot caves as maternity roosts. Peters’s Ghost-faced Bats fly higher and faster than other mormoopids, usually foraging in open spaces along canyons and over streams. They are more commonly caught in caves or in other day roosts than in mist nets. They usually become active later than other species of mormoopids, emerging from day roosts after dark. In Ecuador , two activity peaks have been reported. Echolocation calls during search phase consist of steep FM downsweep pulses of ¢.3-5-5 milliseconds, with three harmonics; second harmonic of 48-54 kHz is usually of high intensity.	Peters’s Ghost-faced Bats are found roosting with other bat species, including mormoopids, but spatially separated from them. Large clusters of hundreds of thousands have been observed in some localities, but small groups are more commonly reported. Individuals usually maintain a distance of ¢. 15 cm from each other within the colony. There are seasonal fluctuations in sizes of colonies, with higher numbers of individuals usually observed in the dry season. In Ecuador , populations occupying caves in different geographical regions might maintain gene flow, suggesting high dispersal abilities. There is sexual segregation in roosts at least during part of the reproductive cycle.	Classified as Least Concern on The IUCN Red List. Peters’s Ghost-faced Bats are classified as vulnerable in Ecuador and critically endangered in Curacao due to size of declines and threats faced by populations known in these areas. Peters’s Ghost-faced Bat has a large but discontinuous distribution.	Avila & Medellin (2004) | Bateman & Vaughan (1974) | Birney et al. (1974) | Boada et al. (2003) | Bonaccorso et al.

New Red List assessments will be made after this taxonomic split occurs. Three subspecies are currently recognized.	20000000	Mormoops megalophylla	Least Concern		2019	2016-07-09 00:00:00 UTC	3.1	English	The species is very sensitive to all types of disturbance in the specialist caves in which it occurs. A minimum population size is required to maintain high cave temperature, which once reduced offspring do not survive. Besides that, it is listed as Least Concern because of its wide distribution, presumed large population, and occurrence in protected areas.	Mormoops megalophylla occurs in specialized roosts in deep caves of karstic regions, this habitat is very rare (J. Molinari, pers. comm.). Also found in hot caves (A. Rodríguez-Durán, pers. comm.). A minimum population is required to maintain the temperature of the cave at around 40 C, once the minimum threshold of individuals required to maintain the temperature. If the temperature is reduced, offspring do not survive (J. Molinari pers. comm.). In Ecuador it occurs in caves near cloud forests, at around 2700 m in the Andes (Boada et al . 2003). This bat feeds on insects, chiefly moths, its prey usually has body lengths of 5 to 6 mm. It often forages over water, on forest edges, gaps, or open spaces. It roosts in deep caves, where it hangs singly, separated from their neighbors, in colonies of up to several thousand, but usually of only a few individuals. In north Amerca, large concentrations are found in caves in October and November, but disappear by January - such movements are not always seasonal. Females produce one young per year, between April to June. Nursing females roost separately for males and non-reproductive females (Ceballos and Galindo 1984, Emmons and Feer 1997, Reid 2009, Rezsutek and Cameron 1993, Villa-R. 1966).	Cave collapse can cause localized extinctions, cave vandalism occurs in many regions and countries, and roosting bats they are very sensitive to disturbance (L. Davalos and J. Molinari pers. comm.). In Belize non-regulated tourism in caves is causing problems (B. Miller pers. comm.). In Guatemala there are problems with fire in caves (J. Cajas pers. comm.).	It is locally common, especially when they occupy large caves, and it is rarely in large groups (Emmons and Feer 1997, Reid 2009). The population of Venezuela is likely to occur in only ten caves (J. Molinari, pers. comm.). In caves of southwestern Texas, Easterla (1970) found a predominance of females, Bateman and Vaughan (1974) found a cave with only females, but also obtained evidence of males occupying specific places within the cave for most of the year. Rezsutek and Cameron (1991) found males and non-reproductive females roosting at caveencuentran machos y hembras no reproductivas refugiándose en cuevas diferentes de las usadas por hembras en lactancia.	Decreasing	This species is found throughout south Texas, south Arizona (USA), and Baja California (Mexico) south to northwest Peru and north Venezuela, Aruba, Curacao, and Bonaire (Netherlands Antilles), it is also found on Trinidad and Margarita Island, Venezuela (Simmons 2005). It is discontinuous throughout its range in localized colonies (J. Molinari pers. comm.). ;As a species complex was previously much more widespread, local extinctions have occurred throughout most of its range (L. Davalos pers. comm.). Its area of occupancy is relatively small (J. Molinari pers. comm.).		Terrestrial	Conservation and protection of cave habitat is highly recommended, although this will not guarantee protection of the species (L. Davalos pers. comm.). Through its wide geographic distribution it is found in several protected areas of different levels.	Nearctic|Neotropical		FALSE	FALSE	Global	Simmons, N. B., & Cirranello, A. L. (2023).
