The Intermediate Horseshoe Bat (Rhinolophus affinis) is a bat species of the family Rhinolophidae (“nose crest”) that is very widespread throughout much of the Indian subcontinent, southern and central China and Southeast Asia.

It is listed by IUCN as Least Concern as it is considered common where it occurs, without any known major threats.

Rhinolophus affinis is divided into the following nine subspecies:

• R. a. affinis

• R. a. andamanensis

• R. a. hainanus

• R. a. himalayanus

• R. a. macrurus

• R. a. nesites

• R. a. princes

• R. a. superans

• R. a. tener

It varies in appearance and echolocation characteristics throughout its range, suggesting that this taxon may represent a species complex of closely related species.

The intermediate horseshoe bat has a total length of 58–63 mm (2.3–2.5 in), with a forearm length of 46–56 mm (1.8–2.2 in). Individuals weigh approximately 12–15 g (0.42–0.53 oz).

The intermediate horseshoe bat is widely distributed throughout Asia, occurring from India and China throughout Southeast Asia. It is found in Bangladesh, Bhutan, Brunei, Cambodia, China, India, Indonesia, Malaysia, Myanmar, Nepal, Thailand, and Vietnam. The easternmost extent of its range are the Indonesian Lesser Sunda Islands and Java. It is found at elevations from 290–2,000 m (950–6,560 ft) above sea level.

The Lesser woolly horseshoe bat (Rhinolophus beddomei), also called Beddome's horseshoe bat, is a species of bat in the family Rhinolophidae. It is found in India and Sri Lanka. Its natural habitats are subtropical or tropical moist lowland forests, caves, and urban areas. It is threatened by habitat loss.

It was described as a new species in 1905 by Danish mammalogist Knud Andersen. The eponym for the species name "beddomei" is Colonel Richard Henry Beddome, a British officer and naturalist who spent a good deal of his career in India. Beddome was the collector of the holotype for this species. The holotype was collected in the Wayanad district of India. As Rhinolophus is quite speciose, it is divided into closely related "species groups." Andersen placed the lesser woolly horseshoe bat in the philippensis species group, but Simmons includes it in the trifoliatus species group. Some authors have considered it a subspecies of the woolly horseshoe bat; since 1992, it has usually been accorded full species status.

Head and body length is 7 cm. Forearm 6 cm. Wingspan 33 cm.

Females are larger than males. Pelage is rough-textured and woolly. Body completely dark grayish brown, upper side grizzled. Wing membrane blackish brown. The ears are prominent, well-fluted, and pointy. Complex nose-leaf with distinctive shape.

The Mediterranean horseshoe bat (Rhinolophus euryale) is a species of insectivorous bat in the family Rhinolophidae. It is found in the Mediterranean region and balkan peninsula, as well as parts of Italy.

The head and body are normally between 43 and 58 mm, with a 22–30 mm tail. The wingspan of R. euryale is between 300 and 320 mm, with a standard weight between 8 and 17.5 grams. The upper connecting process is pointed and slightly bent downwards, and is distinctly longer than the lower connecting process, which is broadly rounded when seen from below.

The fur is fluffy, with a light grey base. The dorsal side is grey-brown, with sometimes a slight reddish tinge, while the ventral side is grey-white or yellow-white.

R. euryale tends to live in warm, wooded areas in foothills and mountains, preferring limestone areas with numerous caves and nearby water. Summer roosts and nurseries are in caves, although sometimes in warm attics in the north. Roosts are frequently shared with other horseshoe bat species, although without any kind of intermingling.

The Greater Horseshoe Bat (Rhinolophus ferrumequinum) is an insectivorous bat of the genus Rhinolophus. Its distribution covers Europe, Northern Africa, Central Asia and Eastern Asia. It is the largest of the horseshoe bats in Europe and is thus easily distinguished from other species. The species is sedentary, typically travelling up to 30 kilometres (19 mi) between the winter and summer roosts, with the longest recorded movement being 180 km (110 mi). The frequencies used by this bat species for echolocation lie between 69–83 kHz, have most energy at 81 kHz and have an average duration of 37.4 ms.

The greater horseshoe bat is the largest horseshoe bat in Europe. It has a distinctive noseleaf, which has a pointed upper part and a horseshoe-shaped lower part. Its horseshoe noseleaf helps to focus the ultrasound it uses to 'see'. The greater horseshoe bat also has tooth and bone structures that are distinct from that of other rhinolophids. Its first premolar on the upper jaw protrudes from the row of teeth. For other horseshoe bats, this premolar is very small or non-existent. Also in comparison to its relatives, the greater horseshoe bat has relatively short third and fourth metacarpal bones in its wings. It also lacks a tragus. The Greater Horseshoe Bat is, on average, between 57–71 millimetres (2.2–2.8 in) long, with a 35–43 mm tail (1.4–1.7 in) and a 350–400 mm wingspan (14–16 in); Rhinolophus ferrumequinum also exhibits slight sexual dimorphism, with females being a bit larger than males. The fur of the species is soft and fluffy, with the base of hairs being light grey, the dorsal side hair grey brown and the ventral side grey-white, with juvenile bats having more of an ash-grey tint to their fur. Wing membranes and ears are light grey-brown. The greater horseshoe bat weighs up to 30 grams (1.1 oz) and can live up to 30 years.

The greater horseshoe bat ranges from North Africa and southern Europe through south-west Asia, the Caucasus, Iran, Afghanistan, Pakistan and the Himalayas to south-eastern China, Korea, and Japan. The northernmost occurrence is in Wales. Reaches to the southern parts of the Netherlands, Germany, Poland and Ukraine. Generally the bats live below 800 m asl (above sea level), but it also lives, depending on roost availability and humidity, 3,000 m asl in the Caucasus.

The Big-eared Horseshoe Bat (Rhinolophus macrotis) is a bat species within the Rhinolophidae native to China, India, Indonesia, Laos, Malaysia, Nepal, Pakistan, the Philippines, Thailand, and Vietnam.

The big-eared horseshoe bat was described as a new species in 1844 by English zoologist Edward Blyth. The holotype had been collected by Brian Houghton Hodgson in Nepal. The species name "macrotis" is from Ancient Greek makrós meaning "long" and oûs meaning "ear". It contains many subspecies; a 2008 paper listed seven such subspecies:

• R. m. macrotis Blyth, 1844

• R. m. episcopus Allen, 1923

• R. m. caldwelli Allen, 1923

• R. m. siamensis Gyldenstolpe, 1917

• R. m. dohrni Andersen, 1907

• R. m. hirsutus Andersen, 1905

• R. m. topali Csorba & Bates, 1995

R. m. hirsutus, R. m. episcopus were originally described as full species, but George Henry Hamilton Tate included them as subspecies of R. macrotis in a 1943 publication. In the same publication, Tate included R. m. caldwelli as a subspecies; previously, it was considered a subspecies of R. episcopus.[5][6] Most recently, R. m. siamensis has been considered a full species rather than a subspecies, known as the Thai horseshoe bat.

The big-eared horseshoe bat can be differentiated from other horseshoe bats by its very long ears and a tongue-shaped sella that is long and broad.

The big-eared horseshoe bat is found in several countries in South and Southeast Asia including Bangladesh, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Pakistan, Philippines, Thailand, and Vietnam. As of 2008, its presence was possible but not confirmed in Bhutan. It has been documented at a range of elevations from 200–1,692 m (656–5,551 ft) above sea level.

Mehely's Horseshoe Bat (Rhinolophus mehelyi) is a species of insectivorous bat in the family Rhinolophidae found in Southern Europe and parts of the Middle East. It is distributed in a narrow band around the Mediterranean Sea from North-Western Africa across Portugal, Spain, the Balearics, southern France, Sardinia, Sicily and the Balkan Peninsula to Asia Minor.

The bat is medium-sized for a member of the genus Rhinolophus, with pale lips and grey-brown ears and flight membranes. The fur is relatively thick, with the base of hairs grey-white. Ventral fur is almost white, while dorsal fur is grey-brown; the line between the dorsal and ventral sides is relatively sharp.

The bat is cave-dwelling, preferring areas of limestone with nearby water. It has been known to roost in caves with other horseshoe bats such as Rhinolophus hipposideros, as well as Myotis myotis and Miniopterus schreibersi. It prefers to roost in warmer cave cavities, such as those found in the Cova de Sa Guitarreta (Mallorca), while hanging free on the cave roof.

The Lesser Woolly Horseshoe Bat (Rhinolophus sedulus) is a species of bat in the family Rhinolophidae. It is found in Brunei, Indonesia, and Malaysia. It is assessed as near-threatened by the IUCN.

It belongs to the trifoliatus species group.

The bat is relatively small, with long, woolly, blackish fur. It has a dark and complicated noseleaf with pointed lancet located between the eyes, and a pair of lappets on either side of the sella. It also has large and forward pointing ears.

The bat weighs up to 11 g (0.39 oz) and has a forearm length of 38–48 mm (1.5–1.9 in) .

The species is suspected to be monogamous.

The species is found across Peninsular Malaysia and Borneo, and also suspected to inhabit Singapore.

The species is mostly found in lowland primary forest. It roosts singly or in pairs in caves, hollows formed by trees, and also man-made places like culverts. These were photographed along the Kinabatangan River, Sabah Malaysian Borneo.
