The Marovaza yellow bat or Marovaza house bat (Scotophilus marovaza) is a species of bat found in Madagascar.
It was described as a new species in 2006. The holotype was collected in Marovaza, Madagascar, which inspired its species name.
It is relatively small for its genus. Its forearm is approximately long.
It has been found roosting in the palm-leave thatching of small huts. It roosts singly or in small colonies of up to five individuals. It navigates and locates prey via echolocation; its calls have a frequency of maximum energy of 43.8–48 kHz and a maximum frequency of 58–72.6 kHz. Echolocation pulses last 6–8 seconds. Individuals can be infected with Leptospira.
The Marovaza house bat is endemic to western Madagascar. It is currently known from lowland areas of above sea level.
As of 2017, it is evaluated as a least-concern species by the IUCN.
