The southern lesser yellow bored bat ( Vampyressa pusilla ) is a bat from the leaf-nosed family (Phyllostomidae) that is native to Central and South America.
The genus name Vampyressa is derived from the Serbian wampira (= little vampire) and comes from times when all neotropical bats were considered vampires. The species name pusilla comes from Latin ( pusillus ) and means something like small or pretty.
description
The southern lesser bored bat is a relatively small bat with an average weight of 8.2 g and a forearm length of 31.4 mm. Like most members of the leaf - nose family, it has a pronounced nasal blade . Apart from the two light stripes above and below the eyes, the fur is uniformly brown.
In contrast to the two-toothed bored bat ( Vampyressa bidens ), the species has four instead of two lower incisors. In addition, the third lower molar tooth, which is present in the Melissa's bored bat ( Vampyressa melissa ) and the two-tooth bored bat. In Vampyressa pusilla , as in the Melissa yellow bored bat, the light stripe on the back is missing, which is present in the other three species of the genus. The fur on the back is paler and the light stripes on the face less pronounced than in other vampyressa species. In addition, Vampyressa pusilla is smaller than the Melissa's common drilled bat and the striped drilled bat ( Vampyressa nymphaea ).
Until 2003, the species complex of the Northern Lesser Yellow Boring Bat ( Vampyressa thyone ) consisting of at least three species was still counted as Vampyressa pusilla .
Way of life
Like most bats, the southern lesser capillary bat is nocturnal. It feeds on various fruits, with figs being preferred. Fruits of Ficus yoponensis can be up to 92% of the food make up. The species is relatively rare, but can occur locally in cluster. During the day it probably hangs under leaves, which the animals modify by gnawing the ribs so that the leaf collapses like a tent.
The females are bimodal polyestrial and give birth to a young twice a year.
distribution
The southern lesser yellow boreal bat occurs in eastern South America in southern Brazil , eastern Paraguay and in the province of Misiones in Argentina . The IUCN cannot currently assess their endangerment due to the poor data situation and various taxonomic uncertainties.
