 In the subsequent literature, M. audreyae has seldom been mentioned and never been further described. In a 1999 review of recent extinctions in mammals, Ross MacPhee and C. Flemming reported that M. audreyae had been recovered from a locality on Barbuda known as Darby Sink, which had been radiocarbon dated to around 1200 CE. They also stated that M. audreyae and "Ekbletomys" may in fact be identical. However, in 2009 Samuel Turvey suggested that two different rice rats were in fact present in material from Barbuda, which would imply that M. audreyae is a valid species.
