Assessment rationale/justification
The species is known from only one locality in Bangladesh, but is likely to occur in other localities of the country. A group of about 50 were seen roosting during the day, for at least several days, in a crevice of a building in Jahangirnagar University, Savar, Dhaka, in January 1995. A specimen was collected on 27 January 1995 and was identified as a free-tailed Bat, but the species-level identification could not be done at that time. The preserved specimen was re-examined in 2015 and was identified as Chaerephon plicatus, which is a new species for Bangladesh (M.M.H. Khan pers. obs.). The roosting colony disappeared after January 1995, indicating that it is not a resident in the area. The species is likely to occur in other areas of Bangladesh. There is not enough data to assess its status in Bangladesh. Therefore, it is listed as Data Deficient.
