Thomas's nectar bats, (Emmons, 1990), are found in Central and South America, in eastern Panama, Colombia, Venezuela, Guianas, Amazonian Brazil, Peru, and Bolivia.
These bats occupy lowland rainforests throughout Central and South America. Their distribution is strongly correlated with moist areas such as streams and rivers, and they often roost in caves and hollow trees. Lonchoplylla thomasi can survive in man-made clearings but prefer evergreen tropical forests, and have not been noted above elevations of 851 meters in Venezuela. (Eisenberg, 1989; Emmons, 1990)
This species can be identified by its moderately long and narrow muzzle with a lower jaw that is longer than the upper jaw. This long rostrum houses a long tongue with papillae present at the tip. Their cheekteeth are narrow and elongate, with a dental pattern 2/2:1/1:2/3:3/3 = 34. Combined head and body length ranges from 45 to 60 mm, and the tail from 8 to 10 mm. Weight is usually between 6 and 14 grams. (Eisenberg, 1989; Emmons, 1990)
Thomas's nectar bats have a well-developed spear-shaped noseleaf that is high and narrow. Their tails are short, barely reaching the middle of the interfemoral membrane, and uropatagia are well-developed. The dorsal surface of these bats is usually a dark brown or rusty color, with the underside lighter. They have relavtively short ears with small traguses. (Eisenberg, 1989; Emmons, 1990; Nowak, 1994)

While very little has been discovered regarding the reproductive behavior of Phyllostomidae is a large and variable group, this information may not be applicable to this particular species., some information is available about Phyllostomids in general. However, as
Phyllostomids usually produce a single young, with parturtion occuring in times of maximum food availability. These bats are often highly seasonal breeders. Many species exhibit size dimorphism with females larger than males, probably due to the requirements of bearing young; however, this does not seem to be the case among (Eisenberg, 1989).
Parental investment in reproduction of Thomas's nectar bats is unknown. Like all mammals, femalemust nurse their young.
The lifespan of this species is unknown.
Very little is known regarding the behavior of this species. (Emmons, 1990)have often been discovered roosting in small groups in hollow trees or small caves, suggesting some social behavior.
While researchers do not know much about communication among Thomas's nectar bats, other phyllostomids use echolocation to communicate and percevive their environments, and it is assumed that does so as well. While some bats can see relatively well, their primary sensory ability is through echolocation, in which they emit high-pitched sounds from their noses or mouths and allow them to echo off objects in the environment, giving them a detailed sense of the world around them. Echolocation allows bats to avoid hitting objects when flying at night or in the darkness of caves, and to locate food. Microchiropterans like probably emit sounds having only about one-thousandth the sound energy of bats that hunt moving prey, since they feed on stationary plants. Phyllostomids specifically emit sounds with a low amplitude pulse and a brief, highly modulated frequency. Bats cannot receive information about their environments when their ears are plugged, reinforcing the idea that they perceive their surroundings primarily with echolocation. (Eisenberg and Redford, 1989; Nowak, 1994)
In addition to using calls of lower frequency for communication, some Chiropterans generate a vibration throughout their entire bodies when resting and contented. However, it is unknown if (Nowak, 1994)uses these specific techniques.
The predators ofare unknown.
Positive economic importance is unmentioned in current literature.
While negative impact of Thomas's nectar bats is not mentioned in current literature, other bat species often carry rabies, which can be transmitted to humans if bitten.
