The long-snouted bat (''Platalina genovensium'') is a species of bat in the family Phyllostomidae. It is monotypic within the genus ''Platalina''.〔〔Sahley, C.T., & Baraybar, L. 1996. Natural History of the Long-Snouted Bat, Platalina genovensium (Phyllostomidae: Glossophaginae) in Southwestern Peru. Vida Silvestre Neotropical 5(2). http://www.conatura.org/files/platalina.pdf. Accessed October 29, 2014〕 It is endemic to Peru.〔http://www.conatura.org/files/AJBWeberbauerocereus.pdf〕 It feeds almost exclusively on the nectar and fruit of the columnar cactus .〔Wildscreen Arkive. Long-snouted bat (Platalina genovensium). http://www.arkive.org/long-snouted-bat/platalina-genovensium/ . Accessed 18 November 2014.〕 There are only seven known populations and despite little research having been done on this species, they are listed as near-threatened due to habitat loss causing the removal of their primary food source.〔http://www.iucnredlist.org/details/17487/0〕 == Description ==
〔 Captured long snouted bats range in length from 7.2 to 8.9 cm with a tail length of 0.5 to 1.1 cm and forearm length of 12.8 to 26.5 cm. Weights range from 12.8 to 26.5 g with the upper weight range including a pregnant female.〔http://www.bmap.com.pe/?Peruvian-long-snouted-bat,64〕 More typical measurements are total length around 81 mm, wing extension of 341 mm, and weights of 19.5 to 19.9 grams. Wing area is the largest of any known glossophagine with wing loading the lowest. This may be due to the high altitude.〔http://www.researchgate.net/publication/260084471_The_Peruvian_Long-Snouted_Bat_Platalina_genovensium_Thomas_1928_%28Phyllostomidae_Lonchophyllinae%29_in_the_Area_of_Influence_of_the_PERU_LNG_Gas_Pipeline_Population_Status_and_Recommendations_for_Conservation〕 It is the largest bat within the Lonchophyllinae subfamily. This size could be an adaptation for night temperatures approaching 0c. The bat is known for its extremely elongated muzzle which could indicate increased specialization.〔Wildscreen Arkive. Long-snouted bat (Platalina genovensium). http://www.arkive.org/long-snouted-bat/platalina-genovensium/ . Accessed 18 November 2014〕 In addition, the tongue is long, extendable and covered in papillae. The upper incisors are broad and spoon shaped with a diamond-shaped noseleaf. The interfemoral membrane is long and sparsely haired with the tail extending 1/3 of the way into the membrane. The body is pale brown with the base of each hair being lighter than the tip. The underside is also lighter than the back.
