Yellow-bored bats ( Vampyressa ) are a genus in the subfamily fruit vampires (Stenodermatinae) with six species that occur in Central and South America .
features
The German name refers to the yellow edges of the rounded ears. The fur of these bats is light or dark brown to gray in color. Some species have conspicuous white facial stripes and some species have a different colored back stripe . The nasal blade is pointed upwards.
Yellow-bored bats reach a head-trunk length of 4.3 to 6.5 cm, the weight is between 9 and 12 g. The forearms, which determine the wingspan , are 3.0 to 3.8 cm long. No tail is externally visible.
Types and distribution
According to Wilson & Reeder (2005) there are six species in the genus.
- Two-toothed yellow bored bat ( Vampyressa bidens ), northern South America, in the Amazon basin and adjacent regions.
- Brock's borer's bat ( Vampyressa brocki ), from northeastern Peru to Suriname .
- Melissa Gelatinous Bat ( Vampyressa melissa ), narrow strip east of the Andes from Venezuela to Peru.
- Striped Yellow Boring Bat ( Vampyressa nymphaea ), southern Mexico to northern Ecuador .
- Southern lesser capillary bat ( Vampyressa pusilla ), eastern Paraguay , southern Brazil and the northeast tip of Argentina .
- Northern lesser yellow boreal bat ( Vampyressa thyone ), southern Mexico to northern Bolivia .
In 2014, Vampyressa elisabethae and Vampyressa sinchi, two more species from Colombia, were described.
Way of life
The behavior of these bats has not yet been adequately researched. At the resting place they form small groups of two to seven specimens, which use large leaves to build a kind of tent as protection. Presumably the group represents a harem . Only groups of one male, a few females and their offspring are known of Vampyressa nymphaea . The mating season depends on the distribution area. Like other fruit vampires, yellow bored bats primarily eat fruit.
status
The IUCN lists Vampyressa melissa as endangered (vulnerable), Vampyressa pusilla with insufficient data (data deficient) and all others as not endangered (Least Concern).
