Justification:
Although specimens have been collected from a number of locations in south-east Asia, the abundance of Taenaris horsfieldii is uncertain, with some reports stating that it is rare (D'Abrera 2001, D. Peggie pers. comm. 2008). However, it is sufficiently widespread to qualify as a species of Least Concern, particularly since it is currently not affected by any major known threats.
