Pendlebury’s Leaf-nosed Bat Hipposideros pendleburyi French: Phyllorhine de Pendlebury / German: Pendlebury-Rundblattnase / Spanish: Hiposidérido de Pendlebury Other common names: Pendlebury’s Roundleaf Bat Taxonomy. Hipposideros pendleburyi Chasen, 1936, “cave near the foot of Khao Ram, Nakon Sri Tamarat, Peninsular Siam [= Thailand].” Hipposideros pendleburyi is in the armiger species group. Monotypic. Distribution. Peninsular Thailand. Descriptive notes. Tail 48-70 mm, ear 30—35 mm, forearm 75—81 mm; weight 44-67 g. Males are usually larger than females. Ears of Pendlebury’s Leaf-nosed Bat re large with pointed tip. Hair is long and soft, and dark brown. Tail is long with tip free from interfemoral membrane. Noseleaf is rather small and does not cover muzzle. There are four supplementary leaflets, with outer one very small. Intermediate leaf is thick and swollen. Posterior leaf is thick but narrower than anterior leaf. Adult males have a thick, swollen structure behind posterior leaf. Skull is large with well-developed sagittal crest. Rostrum and supraorbital region are greatly inflated. C1 and j are heavily built. P2 small and extruded from tooth row, so that C1 and P4 are in contact. Habitat. Pendlebury’s Leaf-nosed Bat forages in primary and disturbed forests, seeking its food in the forest itself or in other vegetation near caves. It is also recorded in orchards and rubber plantations. Food and Feeding. Pendlebury’s Leaf-nosed Bat feeds on insects, mosdy Coleoptera and Hymenoptera, in the forest understory and around trees. It sometimes flies high and fest in open spaces, possibly commuting to and from foraging sites. Breeding. Females were found pregnant fromJanuary to early May. Young were sighted attached to females in the roost from February to June. Activity patterns. Pendlebury’s Leaf-nosed Bat roosts in caves, often in large numbers. Echolocation calls are typical F components terminating with a FM tail, with the frequency of the F part of 65-75 kHz. Movements, Home range and Social organization. Pendlebury’s Leaf-nosed Bat forms small to very large colonies in caves. Each individual usually has a roosting space of c.10-20 cm from other individuals. They are often found in mixed colonies with other large Hipposideros species such as Diadem Leaf-nosed Bats (Ä diadema), Large Asian Leaf-nosed Bats (H. lekaguli), or Shield-faced Leaf-nosed Bats (H. lylei). Status and Conservation. Not assessed on The IUCNRed List as a separate species from the Lesser Leaf-nosed Bat (H. turpis), which is classified as Near Threatened. Pendlebury’s Leaf-nosed Bat is widespread and rather common in cave habitats. It has been recorded from several protected areas throughout its range. Bibliography.
